• Quality Control: Understanding Its Importance, Benefits, Approaches and Key Strategies

** Unlock Your Full Potential **

Maintaining high-quality products and services is crucial for success in today's competitive business environment. Quality control (QC) plays a critical role in ensuring that your company consistently meets customer expectations and regulatory requirements. This comprehensive guide will explore the importance of quality control, its benefits, and key strategies, with industry examples to illustrate its practical applications.

What is Quality Control?

Quality control refers to the systematic process of identifying, monitoring and correcting potential defects or deviations in products or services. This process ensures that the final output meets the established quality standards and customer requirements. QC is an essential part of the overall quality management system ( QMS ) and involves regular inspections, testing, and monitoring of various production stages.

ISO 9001:2015 defines Quality Control as “a part of quality management focused on fulfilling quality requirements.” It includes activities such as the inspection and testing of incoming raw materials, in-process products, and finished goods.

History of Quality Control

Quality control has evolved over time to keep pace with the increasing complexity and scale of production processes. Let's take a brief look at the key milestones in the history of quality control:

Craftsmanship Era (Pre-Industrial Revolution): Before the Industrial Revolution, craftsmen were responsible for producing goods and often had a personal relationship with their customers. Quality was maintained by the craftsman's reputation, skill, and pride in their work.

Industrial Revolution (Late 18th Century to Mid-19th Century): With the advent of mass production, the responsibility for quality control shifted from individual craftsmen to factory managers. Inspectors were employed to identify and segregate defective products, but the focus was on finding and fixing defects rather than preventing them.

Scientific Management (Early 20th Century): The introduction of scientific management principles by Frederick Winslow Taylor marked a significant shift in quality control. Taylor's ideas laid the groundwork for more systematic and data-driven approaches to managing production processes, paving the way for modern quality control methods.

Statistical Quality Control (Mid-20th Century): Walter A. Shewhart introduced the concept of statistical process control (SPC) in the 1920s. SPC allowed manufacturers to monitor and control production processes using statistical methods, enabling them to detect and correct defects more efficiently. During World War II, the U.S. military adopted statistical quality control techniques to improve the production of munitions and other equipment.

Total Quality Management (Post-WWII): After World War II, quality management pioneers such as W. Edwards Deming and Joseph M. Juran helped spread the concept of Total Quality Management ( TQM ). TQM emphasized continuous improvement, customer satisfaction, and employee involvement, transforming how companies approached quality control.

ISO 9001 and Modern Quality Control (Late 20th Century to Present): In 1987, the International Organization for Standardization (ISO) introduced the ISO 9000 quality management standards, including ISO 9001. These standards provided a global framework for implementing effective quality management systems. Today, quality has evolved to encompass a wide range of methodologies and tools, such as Six Sigma and Lean Manufacturing, helping businesses achieve higher levels of quality and efficiency.

The history of quality control shows how the concept has evolved and adapted to the changing needs of production processes and market demands. Understanding this history can help businesses appreciate the value of quality control and implement more effective systems to ensure long-term success.

These standards serve as the guiding principles and benchmarks that shape the practices and processes of quality control. Understanding these standards and the certification processes associated with them is pivotal for any business striving for excellence in product quality and reliability.

A. ISO 2859 – Sampling Procedures for Inspection by Attributes

A cornerstone in the realm of Quality Control Inspections, ISO 2859 is pivotal for its role in providing sampling procedures. This standard outlines methods for inspecting a sample batch of products to determine if the entire batch meets the specified quality criteria. It’s particularly relevant in situations where inspecting every single item is not feasible due to time or cost constraints. ISO 2859 helps in determining the sample size, inspection levels, and acceptable quality levels (AQLs) – crucial factors in deciding whether a batch passes or fails the inspection.

B. ANSI/ASQ Z1.4 – Sampling Procedures and Tables for Inspection

Similar to ISO 2859, the ANSI/ASQ Z1.4 standard is widely used for determining sample sizes and setting quality levels. This standard is essential for Quality Control Inspectors in deciding the number of units to inspect from a large batch and in assessing the maximum number of defects acceptable. It plays a significant role in ensuring that the inspection process is both efficient and effective.

C. ISO 9000 Series – Quality Management Principles

While ISO 9000 is typically associated with Quality Management, its principles are directly applicable to Quality Control Inspections. This series provides a set of standards that help organizations ensure they meet customer and other stakeholder needs within statutory and regulatory requirements related to a product or service. Although not specifically a Quality Control standard, ISO 9000 provides the foundational principles that guide the overall quality ethos, influencing the approach and methodology of quality control inspections.

D. AQL (Acceptable Quality Limit) Standards

AQL Standards are critical in Pre-Shipment Inspections. They define the quality threshold level that is considered acceptable. In simple terms, AQL is the maximum number of defective items that could be considered acceptable during the random sampling of an inspection. These standards are vital in decision-making processes during pre-shipment inspections, aiding inspectors in determining whether a product batch should be accepted or rejected.

V. Challenges in Quality Control Inspection

The challenges are as diverse and complex as the processes and products they aim to perfect. For professionals in this field, understanding and overcoming these hurdles is not just part of the job; it’s essential for ensuring the consistent delivery of high-quality products.

This calls for a robust quality management system that can integrate and standardize inspection practices across diverse geographical locations.

C. Balancing quality with cost and efficiency

QCI, by nature, are detailed and time-consuming. In a market where time is money, striking the right balance between thorough inspections and efficient production is crucial. Companies must invest in efficient quality control processes that do not compromise the thoroughness of inspections. This often requires leveraging advanced technologies and methodologies to streamline inspection processes without diluting their effectiveness.

D. Regulatory changes and standards

Regulations and standards are continually evolving, driven by technological advancements, changing market demands, and emerging safety and environmental concerns. Companies must ensure that their Quality Control Inspections are not just compliant with current regulations but are also forward-thinking, anticipating future changes and trends.

E. Human factors

The reliance on human judgment and skill means that there is always a risk of human error. Training and maintaining a skilled workforce, ensuring consistency in inspections, and managing human factors like fatigue and motivation are ongoing challenges in this field.

VI. Conclusion – Quality Control Inspection

As we draw the curtains on our exploration of Quality Control Inspection, it becomes evident that this process is much more than a mere checkpoint in the production cycle. It is a vital cog in the machinery of manufacturing and service industries, ensuring that the wheels of quality and excellence keep turning smoothly.

QCI stands as a testament to a company’s commitment to excellence. It is a promise of reliability and safety to customers, a pledge that every product that leaves the production line is not just good enough, but the best it can be. Through rigorous inspections, adherence to standards, and overcoming challenges, Quality Inspection plays a pivotal role in building and maintaining the trust that customers place in products and services.

This journey through the various facets of inspections – from its objectives and types to the standards, certification processes, and challenges – reveals its complexity and significance. It’s a process that requires precision, expertise, and an unwavering dedication to quality. It’s a process that, though often behind the scenes, is fundamental in shaping the face of a product and, by extension, the reputation of a company.

The Importance of Quality Control in the Industrial Sector

The comprehensive inventory management system has become a part of technological advancement. If you work on the production part, of course, it is familiar with the term quality control (QC). What’s quality control? Quality control (QC) is an important process that any company or business must undertake, especially if the production is in the form of products or services.

Running a QC can be easier with the help of inventory management software. A fully integrated inventory management system enables businesses to monitor stock transfers and quality control. Not doing a thorough QC will cause errors that could later harm the business.

Many companies are implementing the best inventory management software to automate the QC process. Therefore quality control has an important role, as all goods will go through the inspection process before delivery to know whether they meet the company’s standard or not.

What is Quality Control?

Quality control or QC is very necessary for the industrial sector, ranging from manufacturing, and production activities to the results of production. Quality control is a process of checking and testing conducted by a business or a company. Measuring and ensuring that the quality of the product meets the standard.

This process can make an entity in quality assessment of various factors involved in production activities. Generally, those doing QC duty are training personnel who make product quality benchmarks and check visuals in the tests of products that can last before, during, and after production.

Even so, this process is the responsibility of all employees. These tests can be done manually or with the assistance of technology. Moreover, this process could make the quality of the product better before its release to the public.

One of the few experts Dr. K. Ishikawa claims that quality control is an activity to research, develop, design, satisfy consumer satisfaction, and provide good service.

This procedure is vital because it helps improve and control product quality before it is sold, and it helps a corporation reach its goals. The main purpose of QC is to ensure that products are sent to clients in good condition and meet quality standards.

Difference between Quality Control and Quality Assurance

After learning what quality control is, then what is quality assurance and what is the difference? The fundamental difference between the two is that the QA checks into every system and the software needs to run properly.

Quality assurance also focuses more s on disability prevention. QC leads to software testing to increase product quality and meet requirements, thus the emphasis on spotting errors.

Quality assurance (QA) is a proactive process, unlike QC, which is a reactive process. From a different standpoint, if quality assurance has a cost-based approach, quality control is a by-product.

QA involves the process of handling quality issues, while QC verifies the quality of the product itself. Quality assurance is the quality of the audit and for example, the quality control in the inspection process and testing of a product.

The Quality Control Elements

The first element is controlled in management which should be present at QC. Such control is like the management of a job, defined and well-managed processes, integrity and performance criteria, and a record identification.

Competition

In maintaining the quality of the product there must be competition such as qualification, experience, and skill.

The purpose of this closeness is the existence of quality relationships such as staffing, HR management , integrity, trust, organizational culture, motivation, and team spirit. 

How Quality Control Works

There must be some internal methods or procedures put in place when performing quality control. In general, the QC supervisor will ensure the product meets the company’s standards.

They will test, examine, research, and analyze a product’s quality according to company standards and consumer worthiness. Here’s how the quality control process works:

Set a standards

The first procedure is to define the standard. Need to consider what standards should be met before the product is at the release stage.

Does the examination have to be one at a time? Or can you check just a few percent of the production in one batch? Doing this is very important at the beginning, for it will determine the effectiveness of the production and preparation of a product or service.

Aligning the company’s vision and mission

Next is to align the vision and mission of the company with its employees. This is important when running quality control because the main goal is to maintain the quality of the product or service offered.

To achieve optimal results, management and employees must agree on maintaining product quality and standards. To align that vision and mission, the company can train its employees and set standards as in the previous points.

Improve the products offered

After determining the company’s standards (benchmarks) and aligning the vision of the mission of management and employees, the next step is to run the QC. In this quality control procedure, finding out how many products fail is one of the things you should do. Then, the responsible team can fix the product to fit the standards. 

By doing QC, the percentage of products that fail can continue to decrease. So what if that hope is not achieved? What if too many products fail or services that don’t satisfy customers? If it is already at that point, the company must make a plan to improve the production process.

In essence, this process will continue to rotate, to ensure there are no errors or at least minimize errors.

Benefits of Quality Control

Not only about the quality of the product, but quality control also has other benefits that can support the sustainability of the company and survive the market competition. Among others, as follows:

1. Product consistency

For products that go through the QC process, of course, the consistency will be maintained, even starting from raw materials before production. This is the final quality of the product. When running quality control, you must have set the standard at the beginning.

As a result, every individual ensures that the product meets quality standards, — in other words, that there are no defects before the product or service is on the release stage.

2. Increase efficiency

The purpose of this efficiency is in terms of the production process, power, and time. Because, if you do not do a QC, there could be errors or defects in the product after release. Of course, you have to fix it, and it will take time, cost, and effort.

Therefore, it is better to check it from the beginning to avoid damage, so that costs, time, and energy can focus more on other things such as quality development or maybe business expansion.

3. Maintaining customer satisfaction

Implementing QC can reduce and avoid fatal undetected errors. Because if you ignore this process, it can make customers not want to buy products or use your services again.

Of course, there will be customer expectations when producing a product that is already in use. By building good standards that previously customer satisfaction will be maintained because it is one aspect that can affect customer loyalty.

Quality Control Responsibility

• Document inspections and tests on a company’s products or services.
• Monitor, analyze, and also test, and research all products.
• You can recommend reprocessing for any low-quality products to the company.
• Monitoring the process in the manufacture of products and monitoring their development.
• Verify the quality of the product.
• Ensuring all goods produced have a quality that meets the standards that the company has set.

That’s the complete explanation of quality control ranging from understanding, differences with quality assurance, elements, how it works, benefits, to responsibility.

So the conclusion is that QC is an important aspect of producing products or services, in order to ensure quality in accordance with company standards so that it can meet consumer expectations.

The difference between QC and QA lies in their focus. QA focuses on disability prevention, while QC focuses on identifying or finding defects.

In addition, there are also other elements in the QC that are also important for you to know such as control, competition, and proximity. Quality control is closely related to inventory control that can optimize storage in your business goods inventory.

When buying products, customers expect quality all the time. Therefore as a business, it’s your responsibility to deliver products without defects. However, this is not the case in most companies, thanks to the absence of standardized procedures.

Lacking a proper quality control process affects the company’s output and puts your consumer at risk. If your products and services are of poor quality, you’ll spend more time and money reworking them, which eats into your profits in the long run. In addition, your customers won’t be satisfied with your products and will stop doing business with you. As word spreads about your products and services, your reputation will be affected.

This is why quality control procedures are a crucial function in any organization. Implementing a standardized process in your operations is the only way your company will deliver consistent and quality products and services to your customers.

Quality control comes in handy because it spots and removes the sub-standard output at three separate stages:

• When you receive raw materials for production.
• When products are going through the production process.
• Before finished products are dispatched to the customers.

If you are looking to implement a quality control process in your organization or improve the existing procedure, this article will cover all the steps you can use to create and enhance the process, the requirements, benefits, and methods to use as a guide. By the end of the article, you’ll have a clear understanding of why quality control is a must-have in your company.

Definition and Overview

Quality control (QC) is an approach of quality management that businesses use to ensure that the manufactured product or service adheres to a standardized quality criteria and meets the client’s requirements.

Organizations use a set of procedures and benchmarks to ensure that the quality of a product is maintained or improved and errors are reduced or eliminated. Quality control requires inspection and sampling to test whether the final product adheres to the set specifications.

Quality control testing is done at the various steps of manufacturing to identify the problems and help prevent them in the future.

Quality control is a core process in industries that rely on products. For instance, the food and drug manufacturing industries are quite sensitive because the products can cause the consumers to get sick. Companies in this sector perform chemical testing of samples to ensure the final product is free from contaminants to avoid such issues.

Other industries such as automotive and electrical companies also use quality control on their products. The procedures are essential because they help in boosting the safety of the manufactured parts.

Quality control was introduced following the industrial revolution in the 19th century. The rise of mass production prompted the establishment of processes to create parts with identical designs and dimensions. However, the consumers were not satisfied with the results because the processes were not uniform; therefore, quality control was introduced.

During this period, quality control involved using a sketch of the desired product. However, this process became too costly and challenging for most manufacturers. In 1840, companies introduced tolerance limits, and with this method, a design would pass the testing if the parts aligned with the set limits. Manufacturers used devices such as ring gauges and plug gauges to define quality.

The method did not address the issue with defective items; therefore, several methods of quality control were introduced. Here are the different approaches that have been developed over the years.

• Statistical quality control: 1930s
• Total quality control: 1956
• Statistical process control: 1960s
• Company-wide quality control: 1968
• Total quality management: 1985
• Six Sigma: 1986
• Lean Six Sigma: 2001

Once you introduce quality control in your organization, you need to measure its performance. Each company will adopt different standard operating procedures depending on their industry, business size, and nature of business. Here are the common methods used by most corporations.

Six Sigma is a set of quality control tools created by a scientist in the 1980s. This method is a data-driven process that was developed to reduce the defects and variations from set specifications. In statistics, Sigma is the standard deviation from the mean.

With this method, a process needs to have no more than 3.4 defects for every one million events or units. Originally Six Sigma was developed as a management method to enable companies to work faster with fewer mistakes, and has grown to become an industry standard that provides certifications. Companies use this model to boost their profits.

Over the years, Six Sigma has evolved to become a part of business management. Organizations use this method to meet customer requirements, improve customer retention, and sustain the business products and services.

Lean, or lean Six Sigma, is one of the latest quality control methods. This team-focused managerial approach identifies and eliminates waste in the production process to improve efficiency in the organization. In this case, “waste” is the tasks or steps that are deemed unnecessary in the company; therefore, they need to be discontinued.

Companies that use the lean model are focused on eliminating the following:

• Inefficient transportation of materials
• Overproduction that exceeds customer demands
• Too much waiting
• Inefficient processing standards
• Excess inventory levels
• Inefficient work execution by workers and machines
• Work spent fixing production defects

Kaizen in Japanese means change for good; however, it’s loosely translated to “continuous improvement.” This quality control process is quite different because it includes the entire organization, from the top management to the rank and file. If you implement this method in your company, it means that every employee has the opportunity to improve daily.

Organizations that use the Kaizen model also use these implementation tools.

• Gemba Walk: Management and top executives walk around the production floor or manufacturing plant to observe the work, ask questions, and identify areas of opportunity. This model enables the management to know exactly what’s happening.
• SIPOC: Supplies, inputs, process, outputs, and customers (SIPOC) is a process mapping tool that provides clarity in the process workflows. With this tool, the overall process gets optimized, and unnecessary tasks are discontinued.
• 8D Report: Also known as the eight disciplines model, this problem-solving tool resolves and prevents issues identified by quality control personnel. This method identifies and eliminates the root cause of the problem to improve the quality.

X-Bar Chart

Organizations also use quality control charts to measure whether the sampled processes or products are meeting the set specifications. With the X-bar chart method, randomly selected products are tested for the attributes the chart is tracking. On this chart, the Y-axis tracks the variation, while the X-axis monitors the sample tested.

You can use the pattern of variance from the chart to determine whether the facts are systematic or random. Using the results, you can plan on how to improve your quality control processes.

100 Percent Inspection

This quality control method involves examining and assessing all parts of a product. Companies use this method to rule out defects on a product; therefore, it’s common in organizations that deal in produce and metals. Quality control inspectors will need the data on the entire manufacturing process and an inventory analysis.

However, this method comes with some disadvantages. Checking every item that makes up the product is expensive and time-consuming. In addition, if the product is delicate, such as fruits, the inspection process could render it unusable, leading to massive company losses.

Unlike other quality control methods, the Taguchi model focuses on product design, development, and research. Developed by Genichi Taguchi, a Japanese statistician, it seeks to eliminate variances during production before they happen. Companies that use this method aim to reduce the occurrence of defects in their products.

This Taguchi method considers product design to be more important than the manufacturing process. Therefore, the focus is on using research and design to ensure every product will match the set specifications.

For your products to be of high quality, you have to have a strategy in place. A successful and efficient business has effective quality control techniques and procedures to help maintain the consistency of the products across all their locations. If you are unsure about where to start, here are some of the key things you need to build an efficient process.

Create a Dedicated Team for Quality Control

The first step is hiring a dedicated quality control team for the company. According to statistics, more than 122,528 quality control managers are employed in the U.S. Therefore, when searching for personnel, you need to recruit the most qualified candidate and with the right credentials to handle the job.

If your business is a startup with limited capital, it’s still advisable to hire a quality control team to help track and monitor your products’ quality. While you may need to source for extra funds to pay their salaries, the returns are worth it. If your products maintain the quality, you’ll generate more sales and revenue.

When putting together a team, consider their knowledge about the specific product or service they’ll be handling. In addition, you should confirm whether they have worked in this industry before coming to your company.

Consider recruits who understand what the customer wants and the product you are offering so that the quality control process is efficient. You should also recruit top performers who are diligent in their work. Having the right team will streamline your quality analysis procedures and maintain and improve the quality of your products in the long run.

Have a Specific Performance Goal

While this might sound obvious, some quality control teams work without a plan. This is counterproductive and will not meet the company objectives. To build efficient procedures, define success, and take all the steps necessary to improve the quality of your products and services.

During the initial phase, quality control teams need to track the existing procedures and identify any problems that affect the quality of processes. Once this step is complete, the next step is to eliminate all the tasks and steps that interfere with the ultimate goals.

For instance, if you identify some defects in your product, you need to develop a roadmap detailing the root cause of the problem and how to eliminate it. With this type of strategy, you’ll improve the consistency of your services and products while meeting customer needs.

Select the Best Quality Control Method for Your Organization

We have identified the different types of quality control methods above. Depending on your business and the industry you are in, you can choose between Six Sigma, lean, Kaizen, Taguchi, X-bar chart, or 100 percent inspection as the method for your organization.

Each of these procedures can be used to improve the overall quality, but you need to use the right tools to boost their effectiveness. If you select one and it doesn’t give you the expected results, you can choose another option until you find the most ideal for your organization.

Implementing a quality control procedure in your organization comes with the following benefits.

Earn More Money

Quality control ensures that your company delivers high-quality products without defects. This process in turn contributes to customer satisfaction and more sales. If your clients are assured of quality products and services, they will shop from your business which earns your company money in the long run.

Increased Customer Loyalty and Referrals

Customers are more likely to refer you to their friends and family members if your products are of a high quality. Statistics show that 82 percent of small businesses say referrals are their main source of revenue; therefore, it’s important to build that reputation. In addition, your customers become loyal to your brand because of consistency. For this reason, you should have an efficient quality control procedure in place.

Enjoy a Better Brand Image

When you have a quality control procedure for your company, all your products will be uniform and meet the same high standard. This plays a big role in building public confidence in your product. Consumers who have tried your products will have positive reviews about your brand, significantly boosting your image.

Reduce Liability Risks

Quality control is implemented to identify defects in your products and services. If you don’t test your finished products, you’ll be putting your consumers at risk. In addition, your company might get into legal trouble in case the products harm your customers. For instance, the company Takata Corporation had an airbag recall because of increased cases of airbag explosions during deployment leading to injuries and death. These types of liabilities can be costly to your organization if you don’t have quality control.

Meet Regulatory Requirements

Quality control is also critical for your business because it keeps your operations within the regulatory requirements. Organizations are checked against the ISO 9000 set of standards, ensuring that their operation meets stakeholder and customer needs under the statutory regulations. ISO 9000 standards are fundamentals of quality management systems; therefore, they are used by organizations globally to document the quality elements. Quality control is a part of these standards—they play a big role in ensuring that the company is not breaking the law.

Boost Organizational Safety

One of the benefits of introducing quality control in your company is its impact on your employees. Since they know that quality is important, they become keener and monitor all the procedures carefully. This effect will also trickle down to all the areas of business. Employees will become efficient during production to reduce the chances of error and accidents on the production floor.

Gain Competitive Advantage

If your customers are happy with your products, you’ll get more sales. As they become more loyal, you’ll gain a competitive advantage over the other companies in the same industry. Consumers tend to source products and services from organizations with a good reputation. Therefore, if you want to outsmart your competitors, invest in quality control protocols for your products.

Some of the most successful brands in the world have incorporated quality control procedures in their operations. Let’s look at some of the best examples.

How Toyota Used Kaizen

Kaizen, or “continuous improvement,” is one of the major principles in The Toyota Production System . The company uses this philosophy to ensure that its products are of high quality while eliminating waste and improving efficiency in their work procedures.

By following the principles of Kaizen, they have improvements in their standardized work. These standards involve following the set procedures consistently, making it easier for employees to identify defects.

Since this method involves all the employees, from the management to assembly line workers, the Toyota Production System is humanized. Every member of staff can identify areas that need improvement and suggest solutions. According to the company, every staff member has the responsibility to adopt the standard procedures and eliminate waste.

Motorola’s Use of Six Sigma

Six Sigma was introduced in 1986 by a scientist working at Motorola. This methodology was incorporated into the company procedures to reduce mistakes while documenting the manufacturing procedures.

Motorola introduced this quality control method during this period because they faced fierce competition from similar organizations overseas, especially in the Japanese market. Additionally, at this time, the customer complaints about their products were pretty high due to product defects and customer support; therefore, they had to take action.

To deal with this problem, the company introduced Six Sigma, which improved the company’s performance significantly. Between 1986 and 1991, Motorola had hit every target for improvement in different business functions.

Microsoft Using Six Sigma

As one of the largest software producers in the world, Microsoft has tons of customers. To improve the reliability of their network, the company had to use Six Sigma techniques. This method also helped them eradicate defects in their data centers and systems and reduce the failure incidences in their infrastructure.

Microsoft collected data based on past high-priority incidents, server issues, and customer recommendations. This historical data was used to develop a road map on addressing these problems and improving the quality of their services.

Once the company had all the data, they identified the defects and solutions for each of them. The company prioritized all the issues depending on how severe the disruption was. Using the Six Sigma method, the organization had improved the defects by about 40% within the first year. Furthermore, the server failure period improved from 18 days to 125 days. Thanks to these procedures, Microsoft improved the performance of their services, increasing customer satisfaction.

Lean Six Sigma at Dell

Lean Six Sigma had a significant role in Dell’s success. In the early 2000s, the company adopted this technique of quality control to improve its product.

Dell enjoyed massive success between 1997–1999 and increased its revenue from $7.8 billion to $18.2 billion. Once the company implemented the lean Six Sigma model, it saved up to $1.55 billion and achieved the highest profitability by 2004.

With this process in place, the organization increased its efficiency; therefore, customers enjoyed better service and received their computers much faster. At the same time, Dell cut down wastage and turn-around time and started listening to their customers. This quality control tool boosted Dell to become one of the most profitable companies globally.

Kaizen in TOTO Ltd

Just like with Toyota, Kaizen was also implemented at TOTO Ltd. TOTO is a Japanese manufacturer that specializes in plumbing fixtures. The company adopted the Kaizen philosophy to create a comfortable environment for employees and people with disabilities.

Thanks to this quality control technique, the company rearranged supplies for easier handling and better transportation. In addition, the executives introduced new procedures, including using flexible cords to stabilize hanging screwdrivers, which eliminated more than three working hours per month. This saved the company money on salaries.

Quality control (QC) and quality assurance (QA) are mostly used interchangeably. However, that should not be the case since they are quite distinct. Here are the major differences between the two.

Quality Control

Quality control is the process of inspecting products to ensure that they meet the required standards. Quality control is based on inspection and aims to take the defects out.

Quality control was introduced during the industrial revolution in the 20th century following the rise of mass production. Businesses needed a system to check the quality of their products.

Quality Assurance

On the other hand, QA is based on processes and aims to build in the quality without inspecting. These are the processes that a company puts in place to ensure the production quality aligns with the customer’s needs.

Businesses perform quality assurance to design how a product or service will be delivered and eliminate the chances that it will be sub-standard. The focus of QA is during the product development phase, making it easier to build in the quality. Therefore, if the production process is done well, there will be no need to inspect or do quality control on the finished product.

Quality assurance was first introduced in the Middle Ages. Guilds were formed to ensure a standard of quality was maintained. QA continued during the industrial revolution. Over the years, the process has evolved and led to the introduction of statistical control, total quality management, and ISO standards.

List of Differences

Here are the differences between quality control and quality assurance that you need to know.

• Quality control is a process that fulfills the quality request.
• Quality control aims to identify and improve defects.
• It verifies quality.
• The testing team is responsible for quality control.
• It involves executing the planned process.
• It ensures the results align with your expectations.
• This process verifies the deliverables.
• It ensures that the standards are followed when developing a product.
• The statistical technique on quality control is referred to as statistical quality control (SQC).
• QA is a process that aims to provide confidence that quality requirements will be fulfilled.
• QA aims to prevent product defects.
• This technique manages quality.
• All the team members are responsible for quality assurance.
• QA is not involved in executing the program.
• The process ensures the company is doing the right thing.
• QA creates the deliverables.
• QA defines the methodologies and standards to be followed to meet customer needs.
• The statistical technique used on QA is referred to as statistical process control (SPC).

How They Work Together

Quality control and quality assurance work together in an organization as part of the quality management system (QMS). QMS incorporates policies, planning, improvement initiatives, and quality control and QA procedures to boost business efficiency.

These two procedures work together in the following areas.

Customer Focus

Both quality control and QA are essential in meeting customer needs and are implemented to exceed expectations. Once your team understands customers’ current and future needs, it becomes easier to succeed. This strategy leads to increased customer value, loyalty, and satisfaction.

Employee Engagement

To deliver value to your customers, you need to engage all the employees at all organization levels. Quality control and QA techniques can be used to involve all the people in the company. This leads to increased motivation, enhanced personal development, and encourages more involvement in company activities.

When QA and quality control procedures are in place, leaders provide direction and create conditions for all employees to be engaged.

Organization Improvement

Organizations with an efficient QA and quality control process focus on improving all the business functions. This allows the business to maintain its high performance, prevent errors, and take corrective actions.

Relationship Management

Quality management processes in an organization help manage relationships with other parties such as suppliers. With proper relationship management, your company will enhance its performance and create a common understanding of the goals and values.

Process Approach

Companies need efficient QA and quality control techniques to produce consistent and predictable products and services. These processes come in handy in the company to help optimize the system and its performance.

If you are looking to create a quality control process in your company, here are the steps you can use as a guide.

Decide on Your Quality Standards and What You’ll Focus On

You need to set quality standards that you plan to follow in each department. Fortunately, some industries have guidelines created by an external organization or regulatory body. In this case, you have to follow these standards. However, if your industry does not have any external procedures, you’ll need to create your own.

When developing these standards, ensure that every department has quality control procedures that are measurable. This will help you track and monitor any issues and areas for improvement.

In addition, you can choose to focus on the important measures that have a significant effect on customer experience and your profits. This way, your business can get results quickly without overwhelming your team. Focusing on quality standards that are needed by your customers is the best way to improve their experience and ensure satisfaction.

Create Processes That Will Ensure You Deliver Quality

You’ll deliver high-quality products and services if you have a well-designed quality control process. You’ll need to continually measure the success of your quality control procedure and implement improvements to make your products and services better. For instance, you can start with the critical operations in the business and create a guide with benchmarks.

Additionally, these processes should be incorporated in every department. If you deliver quality, your customers will keep coming back because of the high-quality products and services.

Evaluate Results

The only way to know how your quality control process is performing is by reviewing the results. Use your business software, customer relationship management (CRM) tools, financial apps, and customer service tools to customize your information and collect data. These reviews will provide information on whether the company is meeting its standards.

Failure to evaluate your results will lead to poor quality products and services. If a quality control process is not working properly, you might miss the indicators that something needs to be improved.

Ask for Further Feedback

Apart from your company tools, you should also get external feedback from online ratings and reviews and customer surveys. This form of feedback is critical because it provides real-time information from the consumers on the quality of your products and services. You can use this information to improve your products.

Customer feedback provides first-hand information on the effectiveness of your quality control system. Always pay attention to these reviews to help you improve your operations.

Improve Your Processes Based on the Results

Even if you are meeting your quality standards, you should strive to do better. Once you get feedback on your quality standards, you should not stop there. Find ways to improve your quality and delivery of services to keep the customers satisfied.

When your processes are improved, your quality of products and services will become better. Otherwise, if you are stagnant, your bottomline will be affected.

Quality control processes are important because they help your business meet customer expectations. If you consistently improve your company processes, you’ll enjoy continued success and deliver quality products that align with the industry standards. Here are some tips you can use to enhance your company procedures.

Involve All Employees

For the quality control procedure to be effective, you need to engage all employees. This encourages them to adhere and commit to the set standards. You can enforce these procedures easily by training new hires during the onboarding period. Additionally, you can conduct refresher training every year to remind the employees that quality control is everyone’s responsibility.

If your company has a top-down approach, you need to transform it into a bottom-up approach to reach employees in all levels. Your quality control system will become better when everyone is working on a common goal.

Be Flexible and Proactive

During audits, ensure that you reinforce quality procedures and have regular checks to identify non-conforming employees. Typically, a company will have one external audit every year. However, others have several internal audits to keep track of company performance, either quarterly or twice a year.

After these audits, keep employees updated on the new quality control processes. Encourage them to share their feedback and suggestions on how the quality can be improved further.

Automate Records as Much as Possible

Paper-based record-keeping can be tiresome and time-consuming for any business. Ensure that you automate most of your records to make it easier to monitor and track quality standards and procedures. Digital recordkeeping saves time and helps in consistently recording internal checks.

In addition, you should automate all reporting systems from the employees. This way, they can send suggestions and comments in real-time about the progress of the quality control processes.

Take Advantage of All Improvement Tools and Opportunities

During reviews, use all the information you get from surveys, past mistakes, incident reports, and customer reviews to improve your quality control procedures. It would be best if you also stayed up to date with the latest industry best practices that can be used to improve your processes.

You can use internal and external tools to improve your systems. Ensure that every employee understands how the tools work to make system improvement much easier.

Maximize the Use of Technology

New technologies save time spent inspecting products and services. Invest in digital tools that make it easier to automate monitoring. You can find new ways to improve your quality control processes with these resources. Research the current industry trends and incorporate some of the technologies being used by your competitors.

What is quality control (qc), key components of quality control, types of quality control, why is quality control important what are the benefits, quality control roles and responsibilities, quality control vs. quality assurance, quality control careers, what does quality control mean, what are 3 examples of quality control, train to assess quality with lean today.

In today’s world, it’s not uncommon that we take the reliability and quality of products and services for granted. At the start of the 20th century, however, quality control in manufacturing was not exactly a reliable process.

Now, decades after early pioneers created business problem-solving processes and analysis frameworks to determine and control consistency and value, it’s possible more than ever for a business to implement and scale best practices. 

Quality does not have a singular definition. Despite the relative meaning of “value,” quality control is the process by which products/services are tested and measured to ensure they meet a standard. Through this process, a business can evaluate, maintain, and improve product quality. The primary objective of Quality Control is to identify and correct any deviations from the established quality standards. This process involves monitoring and inspecting products or services at various stages of production or delivery to ensure that they meet the desired level of quality. QC is also concerned with preventing defects or errors from occurring in the first place by implementing measures to control and improve the production or service delivery processes.

Ultimately, there are two crucial goals of quality control: (1) to ensure that products are as uniform as possible and (2), to minimize errors and inconsistencies within them.

Key components of Quality Control may include:

Inspection: Regularly examining products, materials, or services to identify defects, non-compliance, or deviations from quality standards.

Testing: Conducting various tests and measurements to assess the performance, functionality, or characteristics of products or services.

Statistical Process Control (SPC): Employing statistical techniques to monitor and control the production processes, ensuring that they remain within acceptable quality limits.

Documentation and Records: Keeping detailed records of inspections, tests, and corrective actions taken to maintain traceability and accountability.

Corrective Action: Implementing appropriate measures to address any identified quality issues and prevent their recurrence.

Training and Education: Providing employees with the necessary skills and knowledge to maintain quality standards effectively.

Continuous Improvement: Constantly analyzing data and feedback to identify areas for improvement and enhancing the overall quality management system.

Quality Control is closely related to another quality management concept called Quality Assurance (QA). While QC focuses on detecting and correcting defects, QA concentrates on preventing them from occurring in the first place by setting up robust processes and procedures.

Together, QC and QA form the backbone of an organization's quality management system, helping to ensure that products and services consistently meet or exceed customer expectations and regulatory requirements.

Quality Control Process

Normally, quality testing is part of every stage of a manufacturing or business process. Employees frequently begin testing using samples collected from the production line, finished products, and raw materials. Testing during various production phases can help identify the cause of a production problem and the necessary corrective actions to prevent it from happening again.

Customer service reviews, questionnaires, surveys, inspections, and audits are a few examples of quality testing procedures that can be used in non-manufacturing businesses. A company can use any procedure or technique to ensure that the final product or service is safe, compliant, and meets consumer demands.

QC Is Different by Industry

Quality Control (QC) is an indispensable aspect of various industries, ensuring that products and services adhere to predefined standards. In the manufacturing sector, QC involves rigorous inspection and testing of raw materials, intermediate components, and final products to maintain consistent quality and minimize defects. In the food industry, QC guarantees the safety and integrity of consumables through thorough testing for contaminants and adherence to health regulations. In the pharmaceutical sector, QC plays a critical role in verifying the potency and purity of drugs, ensuring they are safe for consumption. Additionally, in the software industry, QC involves extensive testing of applications and programs to identify bugs and errors before release, guaranteeing a smooth user experience. Across all industries, QC is a fundamental process that enhances customer satisfaction, boosts efficiency, and fosters a reputation for reliability.

Just as quality is a relative word with many interpretations, quality control itself doesn’t have a uniform, universal process. Some methods depend on the industry. Take food and drug products, for instance, where errors can put people at risk and create significant liability. These industries may rely more heavily on scientific measures, whereas others (such as education or coaching) may require a more holistic, qualitative method. 

At its core, quality control requires attention to detail and research methodology. 

So, what is quality control? There are a wide range of quality control methods , including: 

Control Charts:

A graph or chart is used to study how processes are changing over time. Using statistics, the business and manufacturing processes are analyzed for being “in control.” 

Process Control:

Processes are monitored and adjusted to ensure quality and improve performance. This is typically a technical process using feedback loops, industrial-level controls, and chemical processes to achieve consistency. 

Acceptance Sampling:

A statistical measure is used to determine if a batch or sample of products meets the overall manufacturing standard. 

Process Protocol:

A mapping methodology that improves the design and implementation processes by creating evaluative indicators for each step. 

There are other quality control factors to consider when selecting a method in addition to types of processes. 

Some companies establish internal quality control divisions when defining what is quality control. They do this to monitor products and services, while others rely on external bodies to track products and performance. These controls may be largely dependent on the industry of the business. Due to the strict nature of food inspections, for example, it may be in a company’s best interest to sample products internally and verify these results in a third-party lab.

Quality Control (QC) is essential for various reasons, and its importance lies in the numerous benefits it brings to both businesses and consumers. Here are some key reasons why QC is crucial:

Customer Satisfaction: QC ensures that products and services meet or exceed customer expectations, leading to higher satisfaction levels and increased customer loyalty.

Defect Prevention: By identifying and correcting issues early in the production or service delivery process, QC helps prevent defects, reducing the likelihood of expensive recalls or rework.

Cost Reduction: Implementing QC measures can lead to reduced waste, lower production costs, and improved operational efficiency, contributing to overall cost savings.

Compliance and Regulations: QC ensures that products and services adhere to industry standards and regulatory requirements, avoiding legal issues and penalties.

Brand Reputation: Consistent high-quality products or services build a positive brand image, enhancing the company's reputation and competitiveness in the market.

Increased Efficiency: QC optimizes processes and identifies areas for improvement, leading to increased productivity and streamlined operations.

Risk Mitigation: Through rigorous testing and inspections, QC helps identify potential risks and hazards, enabling businesses to address them proactively.

Continuous Improvement: QC encourages a culture of continuous improvement, where organizations strive to enhance their products, services, and processes constantly.

International Competitiveness: High-quality products can open doors to global markets, increasing a company's competitiveness on an international scale.

Customer Retention and Loyalty: Satisfied customers are more likely to remain loyal and recommend the brand to others, contributing to long-term business success.

Overall, Quality Control is crucial for maintaining high standards, minimizing risks, and fostering a competitive advantage in today's dynamic and demanding business environment. It serves as the foundation for delivering superior products and services while ensuring customer satisfaction and loyalty.

When answering what is quality control, it is critical to understand that it consists of multifaceted responsibilities and roles. Moreover, it shouldn’t be confused with quality assurance. Whereas quality assurance looks at the processes used to prevent defects, quality control is focused specifically on the measurement and analysis processes involved with determining product quality. 

Quality control uses specific research tools to accomplish fact-finding processes and conduct analyses. A quality control professional is tasked with analyzing these measurements against some sort of standard determined by the quality management department, company policies, and industries or regulatory bodies. Based on this evidence-gathering, quality control will recommend changes. 

We can see from this roadmap, too, how quality assurance and quality control differ. Quality assurance looks at the holistic picture to prevent a product from becoming defective. Quality control, on the other hand, later determines if a product is, in fact, defective or not. Both roles fit under the broad umbrella of quality management. 

Thus, an individual in quality control is tasked with communicating results to stakeholders and significant parties. A good quality control specialist will be able to disseminate scientific and research-based thinking to a business community and assist with the problem-solving process. These specialists are a key component of a product’s design process, as they determine whether a company’s creation is truly acceptable for the market.

Even though the terms quality control and quality assurance are sometimes used interchangeably, they have some key differences. Quality criteria, such as ensuring an item complies with specifications, are the main emphasis of quality control. Quality assurance is the sum of all processes and actions necessary to demonstrate that the requirements for quality are satisfied.

Quality control can be a fulfilling job if you enjoy dealing with people, talking, presenting results, and trying to make things better and safer. Depending on the sector, you may need the following qualifications to work as a quality control inspector:

• Entry-level positions require a high school diploma.
• Depending on the business, a bachelor's degree
• A background in the industry
• Certain businesses and sectors require licenses and certifications.

Additional characteristics required by quality control specialists include:

• Observation of details
• Talents in math and mechanics
• Physical prowess and power
• Technical expertise
• Pressured performance

Career Path

There may be discrepancies because the path to quality assurance and control job varies by industry. However, you'll typically require a number of years of professional expertise in your field. After completing the necessary educational qualifications and gaining the necessary work experience, you are often hired as a quality assurance or control associate.

As you gain job experience, you can advance to the position of senior specialist and start leading groups of quality control specialists.

Your employer may require you to take professional development classes or obtain certifications like Six Sigma . A professional designation like Certified Quality Inspector may also be required.

Quality Control Salaries

Depending on the role, expertise, and industry, quality control specialists make a variety of salaries. As you get more expertise and advance into management positions, your pay rises. The average wage, as reported by the Bureau of Labor Statistics, is:

• Services rendered by experts in science and technology: $46,280
• Production: $40,020
• Trade in bulk: $37,800
• $30,070 for office supplies and support services

Quality control refers to a company's methods for assessing product quality and, if necessary, improving it. There are various ways to perform quality control, including benchmarking, examining manufacturing procedures, and testing products. All of this is done to keep track of significant product differences.

Three examples of quality control in the food sector are monitoring ingredient standards, verifying supplier lists, and making sure the manufacturing facility is hygienic.

This course focuses on two important management methodologies — Lean practices and Six Sigma — that will enable you to accelerate business improvement.

1. What is Quality Control (QC)?

Quality control is the process by which services/products are measured and tested to ensure they are as uniform as possible and meet a standard. It helps businesses minimize inconsistencies and improve product quality. 

2. What are the four types of Quality Control?

The four types of quality control are process control, control charts, acceptance sampling, and product quality control. While a control chart helps study changing processes over time, process control and product quality control help monitor and adjust products as per the standards. Acceptance sampling is a unique type that involves a statistical measure to determine whether a batch or sample of products satisfies the standards. 

3. Why is Quality Control important?

Quality control is important to safeguard the company’s reputation, prevent products from being unreliable, and increase trust on the side of consumers. It ensures that the company looks at evidence-based data and research rather than anecdotal observations to ensure that the services/products live up to the standards. It reduces cost and maximizes profit, operational efficiency, and customer satisfaction.

4. What are three examples of Quality Control?

Some examples of quality control are: a high-speed car manufacturer runs thorough tests for every component, including manual and automated verifications; websites study the average response time per page for customer interactions and generate tickets when the service gets unacceptably slow; retail store owners employ secret shoppers to test the customer service of their stores. 

5. What are the four steps of Quality Control?

The first step for quality control is to set your quality standards and decide which ones to focus on. Secondly, you must establish operational processes to deliver optimal quality and implement them. The third step is to review your results and identify gaps. Lastly, get feedback and make improvisations.

6. What are quality control techniques?

Inspection and Statistical quality control (SQC) are the two major techniques of Quality Control. Inspection checks the performance of items as per the pre-decided specifications. It involves periodic checking before, during and on completion of the process. It can be categorized into two types: Centralized and Floor Inspection. Statistical Quality Control relies on laws of probability. It controls the production quality within tolerance limits via sample procedure.  

7. What is the difference QA and QC?

Quality Assurance (QA) focuses on preventing defects and maintaining the overall quality management system through process implementation and improvement. It ensures that proper processes are in place to avoid issues. On the other hand, Quality Control (QC) involves detecting and correcting defects through inspections and testing. QC ensures that products or services meet specific quality standards. While QA is proactive, emphasizing prevention, QC is reactive, emphasizing identification and correction of issues after they occur.

Quality Control Process: Definition, Approaches, and Steps

When it comes to retaining loyal customers, companies have just one tool that’s powerful enough to appeal to every type of customer/audience they’re targeting. Yes, we’re talking about quality.

A product or service that meets the quality expectations of buyers will always keep them happy and coming back for more. But how can companies manage quality and keep it consistently high at all times? The answer lies in the quality control process.

What is Quality Control?

“Quality” refers to the degree of excellence or superiority that something possesses compared to things of a similar nature.

“Quality control ” refers to the set of activities, processes, and operations that companies have in place to maintain and improve the quality of the product/service they are offering.

Factors that Determine Quality

Quality is a subjective experience and differs based on industry and the type of product/service purchased. But ultimately, the following factors work together to increase quality in the eyes of the customer:

Type of Raw Materials Used

The type of raw materials used to create the product/service should be more long-lasting, functional, aesthetic, sustainable, and easy to obtain in the long run.

Functionality/Usefulness

This defines how useful the product/service is to the buyer after the purchase. Does the product/service offer additional value to their life by either solving an existing problem or filling a gap they have?

The type of features and their sophistication, device optimization, accessibility, variety, etc., all affect how useful a product/service can be to a buyer.

These features will determine whether the company’s offering is a better investment compared to other similar products.

Affordability is one of the key determinants of quality, especially in terms of the price buyers pay for the features they receive.

Adherence to Benchmarked Standards and Quality Compliances

Products/services that hold labels such as ISO, ISI, AGMARK, BIS, GI, GDPR, ADA, etc., indicate that the product/service conforms to stringent global compliance regulations, automatically improving their quality.

These days, companies must focus on creating products and experiences that have the least ecological impact and can meet Governments’ measures for anti-pollution and climate change reversal.

Variety and Accessibility

Even within one target group, there are often differences in tastes between customers. More variations of the product/service can make it more accessible and enjoyable to all your customers.

In the eyes of buyers, the safer a product/service is to use or experience, the better its quality. Similarly, safety also refers to protection against tampering by unauthorized individuals.

Reliability and Longevity

The longer the uninterrupted, seamless service a product/service offers and the higher its shelf life, the better it is considered by buyers.

Approaches to the Quality Control Process

In order to maintain high quality always and to consistently keep improving the quality of the product/service being provided, companies need to have a powerful quality control process in place.

Depending on their needs, a company might use one of these approaches to quality control:

Random Selection

Here, a random sample of the product/service is taken to measure select attributes (such as product durability, accessibility, or safety) to identify the item’s quality.

This approach helps the company determine if defects exist across the board or if they are isolated to specific attributes/batches/production cycles.

Taguchi Method

In this method, the focus is on the role of R&D and product design and development in product quality.

The foundational operations such as research, methodology design, and technology selection are made with greater care to reduce failures/errors in the later stages of product/service production.

100% Inspection

This approach is a comprehensive, 360-degree quality check process. Here, every stage of production is monitored and controlled to meet quality requirements. This takes a lot of time, but it is an approach that offers excellent quality results.

Quality assurance takes quality control a step further. It is a mindset adopted by the entire company, which aligns every activity, thought, and decision towards always striving for the best quality possible.

Here, quality is built into every single action, process, and technology that is related to the product/service in any way (including functions outside R&D and production).

Steps Involved in Quality Control 

The fact is companies often lose 10%-15% of their operations cost or 15%-20% of their sales revenue due to poor quality .

A responsive and customized quality control and assurance process can help companies create products/services that always adhere to their benchmarked standards.

The quality control process typically looks like this:

Incoming Materials Quality Control

The first step is monitoring the quality of incoming materials. These materials could be physical materials to make a physical product/service or digital materials to offer an online experience.

The materials are inspected to make sure they meet the firm’s quality standards and requirements. Those that don’t are either discarded or returned for modification.

In-Production/Process Quality Control

This second step oversees quality management during the production/processing of the product/service. This could be testing the tool/technology being used to produce the physical item.

Alternatively, it could be testing the safety and accessibility of the digital environment in which the online product/service will operate.

At this stage, the company also checks its adherence to global compliance requirements. Additionally, any client-given specification becomes one of the main points for quality management.

Final/Outgoing Quality Control

In this third stage, the quality of the finished product/service is checked to ensure no defects or deficits exist. The product/service is implemented, and it is examined to make sure it operates seamlessly.

How the product/service looks, whether all features are operational, and if it can be easily used (i.e., downloaded, consumed, shared, etc.) are checked. If there’s something wrong, it is sent back to the production stage for revisions .

Adherence to client specifications is again checked, any necessary labels/marks/tags are added, and the product/service is sent to the desired location. This could be a physical distributor’s warehouse or uploading onto a digital platform.

Even after sale/distribution, the product/service is continually monitored and improved upon as time passes. The best quality control tool gives the company the flexibility to keep improving the quality offered through responsive changes.

Quality control in manufacturing: a guide to quality management in production.

Welcome to our blog, where we dive into the world of manufacturing and explore the critical aspect of quality control. In today’s fast-paced and competitive market, ensuring that your products meet or exceed customer expectations is essential for success. That’s where quality control in manufacturing comes into play – a process that ensures every product leaving your production line is flawless.

In this comprehensive guide, we will take you through the ins and outs of quality management in production. We’ll discuss its importance, the key principles behind it, essential tools and techniques to implement, as well as common challenges faced by manufacturers. So if you’re ready to enhance your manufacturing process and deliver top-notch products consistently, let’s get started!

The Importance of Quality Control in Manufacturing

In the manufacturing world, quality control is like a superhero that swoops in to save the day. It ensures that every product rolling off the assembly line meets stringent standards and satisfies customer expectations. Without proper quality control measures in place, manufacturers risk delivering defective products that can tarnish their reputation and lead to financial losses.

Quality control plays a crucial role in maintaining consistency. By closely monitoring each step of the production process, manufacturers can identify any deviations or defects early on and rectify them promptly. This helps ensure that every unit produced adheres to established specifications, leading to uniformity across batches.

Implementing robust quality control practices enhances customer satisfaction. When consumers purchase a product with confidence knowing it has been thoroughly checked for flaws or defects, they are more likely to become loyal customers who endorse your brand through word-of-mouth recommendations.

Moreover, effective quality control contributes significantly to cost reduction. Detecting and resolving issues early prevents costly recalls or warranty claims down the line. By minimizing rework and waste while maximizing efficiency during production, companies can optimize their resources effectively.

Quality management is an essential aspect of manufacturing that ensures products meet or exceed customer expectations. It involves a systematic approach to monitoring and improving all processes involved in production, from raw material sourcing to final product inspection. By implementing effective quality management practices, manufacturers can enhance customer satisfaction, reduce waste and rework, and ultimately increase profitability.

One key component of quality management is establishing clear quality objectives and standards. This helps set the benchmark for product performance and guides the entire manufacturing process. Manufacturers must also implement robust quality control measures at each stage of production to identify any defects or deviations from the established standards.

Another important aspect of quality management is employee involvement. Engaging employees in the continuous improvement process fosters a sense of ownership and responsibility for product quality. Training programs should be provided to ensure that employees understand their roles in maintaining high-quality standards.

Effective communication within the organization is crucial for successful quality management. This includes sharing information about customer feedback, production issues, and improvement initiatives across different departments. Collaboration between teams allows for timely identification and resolution of potential quality problems.

Continuous monitoring through data collection and analysis plays a vital role in quality management. Various tools such as statistical process control charts can help identify trends or patterns indicating potential issues before they become significant problems.

In addition to internal controls, manufacturers may also implement external audits or certifications to validate their adherence to international standards such as ISO 9001:2015. These external evaluations provide customers with confidence in the manufacturer’s commitment to producing high-quality products.

Understanding quality management in production requires a comprehensive approach that encompasses clear objectives, employee involvement, effective communication channels, continuous monitoring through data analysis, and external validation through audits or certifications.

By embracing these principles of quality management, manufacturers can consistently deliver products that meet or exceed customer expectations while enhancing their competitiveness within the industry.

The 6 Key Principles of Quality Control

When it comes to quality control in manufacturing, there are six key principles that serve as the foundation for effective quality management. These principles guide manufacturers in ensuring that their products meet the highest standards and consistently deliver customer satisfaction.

1. Customer Focus: The first principle emphasizes the importance of understanding and meeting customer requirements. By putting the customer at the center of all decision-making processes, manufacturers can ensure that their products not only meet but exceed expectations.

2. Leadership: Strong leadership is crucial for driving a culture of quality within an organization. Leaders must set clear goals, provide resources, and empower employees to take ownership of quality control initiatives.

3. Involvement of People: Quality control is not solely the responsibility of a designated team or department; it is a collaborative effort involving every individual within an organization. Engaging employees at all levels ensures that everyone understands their role in maintaining high-quality standards.

4. Process Approach: Adopting a process-driven approach helps identify potential bottlenecks or areas for improvement in production workflows. By continuously monitoring and analyzing processes, manufacturers can make data-driven decisions to enhance efficiency and eliminate defects.

5. Continuous Improvement: Quality control should be an ongoing journey rather than a one-time event. Manufacturers must constantly seek ways to refine their practices through continuous improvement methodologies such as Six Sigma or Lean Manufacturing.

6. Evidence-based Decision Making: Data plays a vital role in effective quality control management by providing objective insights into product performance and identifying trends or patterns over time. Using data analytics tools allows manufacturers to make informed decisions based on evidence rather than intuition alone.

By adhering to these six key principles, manufacturers can establish robust quality management systems that drive organizational success and build trust with customers.

Tools and Techniques for Quality Management

Tools and techniques play a crucial role in ensuring effective quality management in manufacturing. By utilizing the right tools and employing appropriate techniques, manufacturers can identify and address potential quality issues before they impact the final product.

One commonly used tool is statistical process control (SPC). SPC involves monitoring key variables during production to detect any variations that may indicate an issue. This allows manufacturers to take corrective actions promptly, preventing defects from arising.

Another important technique is failure mode and effects analysis (FMEA). FMEA helps manufacturers proactively identify potential failures or defects in their processes or products. By analyzing possible failure modes and their impacts, manufacturers can implement preventive measures to mitigate these risks.

Other tools include Six Sigma methodologies, which focus on reducing variability and improving process efficiency, as well as lean manufacturing techniques that aim to eliminate waste throughout the production process.

Furthermore, technology plays a significant role in quality management. Manufacturers can use advanced software systems for data collection, analysis, and tracking of quality metrics. Automation technologies such as robotics can also enhance precision and reduce human error.

In addition to these tools and techniques, it is essential for manufacturers to establish clear documentation procedures outlining standard operating procedures (SOPs) for each stage of production. Regular audits should be conducted to ensure compliance with these SOPs.

By implementing robust tools and techniques along with proper documentation practices, manufacturers can achieve consistent quality levels while minimizing defects and improving overall customer satisfaction.

Quality Control & Quality Assurance

Introduction.

Quality is an important factor when it comes to any product or service. With the high market competition, quality has become the market differentiator for almost all products and services.

Therefore, all manufacturers and service providers out there constantly look for enhancing their product or the service quality.

In order to maintain or enhance the quality of the offerings, manufacturers use two techniques, quality control and quality assurance. These two practices make sure that the end product or the service meets the quality requirements and standards defined for the product or the service.

There are many methods followed by organizations to achieve and maintain required level of quality. Some organizations believe in the concepts of Total Quality Management (TQM) and some others believe in internal and external standards.

The standards usually define the processes and procedures for organizational activities and assist to maintain the quality in every aspect of organizational functioning.

When it comes to standards for quality, there are many. ISO (International Standards Organization) is one of the prominent bodies for defining quality standards for different industries.

Therefore, many organizations try to adhere to the quality requirements of ISO. In addition to that, there are many other standards that are specific to various industries.

As an example, SEI-CMMi is one such standard followed in the field of software development.

Since standards have become a symbol for products and service quality, the customers are now keen on buying their product or the service from a certified manufacturer or a service provider.

Therefore, complying with standards such as ISO has become a necessity when it comes to attracting the customers.

Quality Control

Many people get confused between quality control (QC) and quality assurance (QA). Let's take a look at quality control function in high-level.

As we have already discussed, organizations can define their own internal quality standards, processes and procedures; the organization will develop these over time and then relevant stakeholders will be required to adhere by them.

The process of making sure that the stakeholders are adhered to the defined standards and procedures is called quality control. In quality control, a verification process takes place.

Certain activities and products are verified against a defined set of rules or standards.

Every organization that practices QC needs to have a Quality Manual. The quality manual outlines the quality focus and the objectives in the organization.

The quality manual gives the quality guidance to different departments and functions. Therefore, everyone in the organization needs to be aware of his or her responsibilities mentioned in the quality manual.

Quality Assurance

Quality Assurance is a broad practice used for assuring the quality of products or services. There are many differences between quality control and quality assurance.

In quality assurance, a constant effort is made to enhance the quality practices in the organization.

Therefore, continuous improvements are expected in quality functions in the company. For this, there is a dedicated quality assurance team commissioned.

Sometimes, in larger organizations, a 'Process' team is also allocated for enhancing the processes and procedures in addition to the quality assurance team.

Quality assurance team of the organization has many responsibilities. First and foremost responsibility is to define a process for achieving and improving quality.

Some organizations come up with their own process and others adopt a standard processes such as ISO or CMMi. Processes such as CMMi allow the organizations to define their own internal processes and adhere by them.

Quality assurance function of an organization uses a number of tools for enhancing the quality practices. These tools vary from simple techniques to sophisticated software systems.

The quality assurance professionals also should go through formal industrial trainings and get them certified. This is especially applicable for quality assurance functions in software development houses.

Since quality is a relative term, there is plenty of opportunity to enhance the quality of products and services.

The quality assurance teams of organizations constantly work to enhance the existing quality of products and services by optimizing the existing production processes and introducing new processes.

When it comes to our focus, we understand that quality control is a product-oriented process. When it comes to quality assurance, it is a process-oriented practice.

When quality control makes sure the end product meets the quality requirements, quality assurance makes sure that the process of manufacturing the product does adhere to standards.

Therefore, quality assurance can be identified as a proactive process, while quality control can be noted as a reactive process.

Enterprises usually adopt some quality practices to control the product quality during the manufacturing process in order to assure the delivery of qualitative good products to customers. The quality practices or quality management systems adopted by industries will further evolve due to the changes of quality concepts as time goes by. This chapter discusses the change of quality concepts and the related revolution of quality management systems in the past century. The quality concepts were gradually changed from the achievement of quality standards, satisfaction of customer needs, and expectations to customer delight. Since merely satisfying customers is not enough to ensure customer loyalty, the enterprises gradually focus on customers’ emotional responses and their delight in order to pursue their loyalty. The emotion of “delight” is composed of “joy” and “surprise,” which can be achieved as the customers’ latent requirements are satisfied. Thus, the concept of “customer delight” and the means to provide the innovative quality so as to meet the unsatisfied customers’ latent needs are elaborated on. Finally, a framework of innovation creation is developed that is based on the mining of customer's latent requirements. This outline will manifest the essential elements of the related operation steps.

1. Introduction

It is widely recognized that consumers only buy the goods with good quality, desired functions, and accepted price [ 1 ]. Therefore, industries always adopt several management practices, or even develop some management systems to design and produce the products so as to meet customers’ needs and expectations showcasing good quality and lower costs. But the management practices or systems adopted by the industries are always changed due to the changes of the quality concepts as time goes by. This occurs as several quality gurus give the pragmatic definitions of “quality” over different time periods, thus causing industries to implement different practices or systems to control overall product quality [ 2 ].

In the first three decades of the last century, quality was defined as “conforming to the standards and specifications of a product” [ 3 ]. Thus, the commonly adopted quality practices by industries were the standardization of quality, inspection, and rework. Deming emphasized that “quality is to fulfill the requirements of customers and satisfy them” [ 4 ]. Hence, the meaning of quality was gradually changed to a “customer‐focused” perspective. Enterprises, therefore, committed themselves to satisfy customers’ needs and expectations. Their aim was to pursue customer's satisfaction and loyalty [ 5 , 6 ]. Companies also developed a number of methods to find out customers’ needs and expectations. To this end, in‐depth interviews with customers were performed, customer surveys conducted, and market research was done. But, when Apple announced several innovative products, and their sales were increasing, it became apparent that only satisfying customers’ requirements are not enough [ 7 ]. As a matter thereof the identification and fulfillment of customers’ unsatisfied latent needs was gauged in conjunction with their emotional responses [ 8 ].

Entering the new century, several studies have suggested that merely satisfying customers is not enough to ensure their loyalty [ 9 – 11 ]. The industries need to focus on the customer's emotional responses and provide the products with attractive quality in order to pursue customers’ delight [ 11 ]. It is worth mentioning at this point that Apple is regarded as a future trend setter, as it successfully created several innovative products such as iPod, iPhone, and iPad, triggering increased sales. A strong customer service department equally assisted in causing customers’ delight experiences [ 12 ].

In view of the above, quality concepts have changed. Terms such as “customer delight” are deemed as forming the crucial elements of quality concepts, which are coined as “attractive quality” and “innovative quality” [ 13 ]. The conceptualization of delight is that the emotion of “delight” is composed of “joy” and “surprise,” which can be achieved as the customers’ latent requirements are satisfied. The provision of innovative quality products is the strategic tool to meet the unsatisfied customers’ latent needs and their curiosity. These changes of quality concepts will lead the enterprises to reengineer their existing quality system, in order to develop the innovative quality attributes of products and services alike so as to retain and attract customers. This scenario causes the quality professionals and researchers to further develop and expand the new quality system beyond TQM. Based on performed research it is the author's view that research should focus on developing an effective new quality system.

During the past century, several quality gurus had led the changes of quality concepts. This chapter will discuss the changes of quality concepts during different time periods over the past century. To this end, it will also state the reflected revolutions of quality management systems with respect to the changing quality concepts. These are arranged in Sections 2 and 3, respectively. The development of “total quality management” (TQM) philosophy in the 1980s was an important landmark, which caused the change of new quality concepts and the reengineering of the quality management system, as introduced in Section 4. Based on the performance evaluation of the TQM implementation of TQM, it is worth noting at this point that the “business excellence model” had been proposed during the 1990s. This is elaborated in Section 5. This chapter also introduces the development of an integral model of a business excellence system beyond TQM, based on the realization of TQM.

Section 6 expands on the changes of new quality concepts pertaining to “customer delight” and “innovative quality” based on the investigation of customers’ latent needs in the new century. This chapter includes a system, which may assist and cater for identifying and foster upon customers’ undersatisfied latent needs and delights, enhancing innovative quality, which is addressed in Section 7. The conclusion of this chapter is listed in the final section.

2. The early quality concepts and the reflected quality management system

Since the early twentieth century, manufacturing processes and activities initiated the control practices to assure the product quality [ 14 ]. Manufacturing companies focused on the related productivity and manufacturing costs. As such, the quality concept and control were product‐focused.

2.1. The quality concept of “standard” and the “inspection” control

In 1913 Ford Motor Company, FMC, created the assembly line in their newly opened factory in Highland Park, Michigan due to the influence of the scientific management of Frederick W. Taylor. This resulted in Ford increasing its manufacturing volume [ 15 ]. Ford's assembly line was copied by many manufacturing companies. However, companies turned their attention to control product‐related quality issues. Since manufacturers were more “product‐focused” in that time, the quality concept was, therefore, aimed at “conforming to the standards and specifications of a product” [ 3 ]. This in turn, impelled quality engineers in manufacturing industries to implement the method of “inspection” so as to control the quality of a manufactured product.

Product designers and process engineers designed the standards and specifications of the products, which were based on their critical attributes. They also set up the standards of the manufacturing process and the standards of operations (SOPs). In doing so, the involved workforce was requested to perform the tasks according to the developed SOPs. The quality inspectors checked the dimensions and characteristics of products, detected the errors and failures, and took the necessary actions to improve the product quality.

2.2. The development of process quality control

In order to ensure product quality, companies needed to utilize the “full inspection” method. This was costly, since it required much time and labor efforts, and resulted in high internal quality costs [ 16 ]. Walter Shewhart, thus, created the control chart, a quality technique tool that he pioneered in Bell Laboratories working as a quality control engineer [ 17 ]. He proposed the use of a sampling inspection method instead of a 100% inspection to reduce the overall amount of inspection. The control chart was utilized to monitor the quality performance concerning the critical aspects of a process, whereas the attributes of the product were identified by means of sampling methods [ 18 ]. This enhanced overall effectiveness and also reduced the associated costs.

Sampling inspection and control charts use many statistic tools such as probability theory, the methods of random sample, analyses of sample mean and deviations to name but a few, as means for improving quality levels. Hence, the method of quality control suggested by Shewhart was called “statistical process control” (SPC) or “statistical quality control” (SQC). Sampling inspection may not always ensure product quality, as it might cause fewer defective products to be shipped to customers [ 19 ]. As a result, thereof, it leads to extra outside quality costs. Shewhart, however, had argued that if the missed number of defects was small, then the savings in inspection costs made it worthwhile [ 20 ].

3. The quality concepts and the reflected quality management system in the mid‐twentieth century

More often than not, quality and the associated price of the goods are primary factors that are considered by customers prior to them materializing a purchase [ 21 ]. As such, manufacturing companies mainly emphasis on the control of quality and costs during the manufacturing process, especially the ones that trigger poor quality.

3.1. The development of “quality costs”

In essence, Juran propounded the concept of “quality costs” in his book “ Quality Control Handbook ” in 1951 [ 22 ]. Juran subdivided the quality costs into prevention, appraisal, internal failure, and external failure costs. The performed literature review indicates that the losses due to the production of defects and manufacturing failures are more than the costs of quality control; in particular, the costs caused by internal and external failures. In view of the above, the implementation of SPC could not effectively control the quality costs.

3.2. The quality concept “quality assurance” and the related TQC‐system

After Juran and several quality experts emphasized the quality cost issue, the concept of quality costs was widely accepted by industry. Meanwhile, another quality concept appeared gradually, namely “quality assurance.” However, a large number of experts in the area of quality control, including Feigenbaum, asserted that implementing an SPC system on its own could not effectively control quality costs [ 23 ]. It is worth mentioning that the concept of “quality assurance” was “users‐oriented,” implying that “product possesses the fitness for purpose of use based on its functions” and hence “quality is zero defects and meeting the specifications 100%” [ 24 ].

incoming quality approval,

process quality control,

product reliability,

delivery, and

customer service.

Actually, Feigenbaum's quality concept and ideas were similar to those described by Deming, Juran, and Crosby [ 25 ].

The concepts and approaches of SPC, TQC, and “costs of quality” were introduced in Japan during 1960 by Deming and Juran. The Union of Japanese Scientists and Engineers (JUSE), which was formed in 1946, synthesized the concepts, principles, and approaches of statistical process control and total quality control [ 26 ]. JUSE promoted the practices of TQC and the quality concepts pursuing the zero defect culture and executing the task right first time.

4. The age of total quality management

While Japanese industries adopted the TQC practices, they emphasized the education and training of quality for all employees and the cultivation of a quality culture. Therefore, the implementation of TQC in Japanese industries was very different from the original TQC.

4.1. The emerging of the Japanese company‐wide quality control, CWQC

customer‐focused and quality‐first as the quality policies,

full participation and teamwork,

education and training of quality for all employees,

realization of “do the right thing first time,”

concept and materialization of a “zero defect” culture,

”continuous improvement” as the key quality activity,

everyone is responsible for achieving high quality levels,

emphasizing on the prevention activities and quality assurance,

cultivating a quality culture environment.

Based on aforementioned critical characteristics, the Japanese TQC was acknowledged as company‐wide quality control (CWQC).

The implication of CWQC in conjunction with Japanese industrial competitiveness and strategic advantages facilitated their entrance into western markets. Japanese enterprises enjoyed an increase in global market share by providing the customers with high‐quality products at lower prices [ 27 ]. This in turn, resulted in western companies facing an increased amount of competition from Japanese and other Asian manufacturers.

4.2. The development of total quality management

“customer‐focused” management,

“continuous improvement” as the key quality activity,

top management's promise persistence for pursuing quality,

education and training of quality for employees,

employees’ good quality concept,

quality leadership,

long‐term supplier relationship,

implementation of quality management system,

cultivation of quality culture.

It is the author's view that the TQM was well developed and suitable for western organizations, as depicted in Figure 2 . Thus, it was widely adopted by industries and nonprofit organizations around the world.

Figure 2.

The framework of TQM.

The development of TQM was also influenced by the western quality experts, namely Deming, Juran, and Crosby [ 28 ]. As already stated Deming's quality concept was that “quality is to fulfill the requirements of customers and satisfy them” [ 4 ]. Crosby's definition of quality was also similar, as he defined quality as “conformance to customers’ requirements.” Juran also defined quality as being “fitness for purpose of use, …, it is judged by the users, not the manufacturers, or the merchants” [ 22 ]. TQM was thus an integrated model of management philosophies, quality concepts, and a set of practices, which were also influenced by Deming's 14 points and Juran's quality trilogy. However, to implement the TQM successfully it is necessary to integrate the so‐called “hard side” elements (that is, statistical methods, quality control tools, process standardization, and improvement, etc.) with the “soft side” aspects (that is, quality concept, employees’ participation, education and training, and quality culture, etc.) [ 29 ].

From the mid‐1980s onward, several important quality programs were being launched. Besides the development of TQM, the ISO 9000 system and the Six‐Sigma program (which was initiated by Motorola) commenced in 1987. It is worth noting that up to date, the ISO system has had four revisions in 1994, 2000, 2008, and 2015, respectively. The Six‐Sigma quality scheme was being widely imitated by GE in 1995 [ 30 ]. The successful implementation of Six‐Sigma by Motorola, GE, and several other multinational companies caused the Six‐Sigma philosophy to be globally adopted by a number of industries and organizations [ 31 ].

5. From Malcolm Baldrige National Quality Award to the Business Excellence Model

From the late 1990s to present, the traditional quality concept has seen a number of changes. In the United States of America, the Department of Commerce introduced in 1987 the Malcolm Baldrige National Quality Award (MBNQA) by benchmarking the Japanese Deming Award [ 32 ] to promote the implementation of TQM in industries and nonprofit organizations.

5.1. The national quality award and TQM

The main aim of TQM implementation is to achieve customers’ satisfaction [ 33 ]. This is turn results in a company improving its financial performances [ 34 – 36 ]. The benefits may be seen in areas such as cost reduction, increased market share and profit, and enhanced business competitiveness [ 37 ]. As a result, MBNQA specifically emphasizes business excellence. Besides the implementation of TQM, MBNQA also considers the strategic management, and information management and analyses.

The European Foundation for Quality Management (EFQA) also launched in 1992 a European Quality Award (EQA) [ 38 ]. Based on the performed research, more than 80 countries have established National Quality Awards (NQAs). These NQAs are largely based on the MBNQA, EQA, and the Deming Prize [ 39 , 40 ], and are generally considered to be an effective way of pursuing business excellence, including customer loyalty and better long‐term financial performances. Most of these national quality awards may form part of the TQM system namely, strategic management, performance evaluation, human resource management, and even IT system and innovation.

Meanwhile, the concept of “sustainable development” was also widely adopted in industry [ 42 , 43 ]. Zairi asserted that “sustainable development is based on a perceived need to address environmental deterioration and to maintain the vital functions of natural systems for the well‐being of present and future generations” [ 44 ]. He thus, proposed an integrated model that incorporates the sustainable development into a TQM system. Yang et al. developed a framework of the system of environmental management, which constitutes of 30 activity items themselves belonging to 12 initiatives [ 45 ].

6. The concepts of “customer delight” and “innovative quality” in the new century

A critical strategy of pursuing business excellence is to raise customers’ loyalty, which cannot be assured by grossly satisfying customers. Indeed, even satisfied customers would defect at a significant rate in many industries. It is recognized that customers’ satisfaction is the result of the fulfillment of their explicit needs. As such, satisfaction only of their needs does not directly result in customer loyalty, since the competitors would also fulfill these explicit needs with better customer‐valued products [ 46 ].

Several studies have revealed that the degree of loyalty depends on whether the customers are “totally satisfied” or merely “satisfied” [ 47 , 48 ]. The totally satisfied customers are actually about five times more likely to repurchase a product or service than those who are merely “satisfied” [ 49 , 50 ]. This suggests that enterprises must strive for “total customer satisfaction,” or even “customer's delight” [ 51 ].

“Customer delight” is a new quality concept. A conceptualization of “delight” is the customer's emotional response, which is composed of “joy” and “surprise”—both encountered in the providing process of goods/services [ 52 ]. In order to delight customers, the enterprises need to provide the goods/services with attractive and innovative quality incentives. The strategic actions are to identify customers’ latent needs and to create customer value by developing the innovative products and attractive services in order to fulfill these.

application innovation,

product innovation,

process innovation,

experience innovation,

marketing innovation,

business model innovation,

structural innovation, and

disruptive innovation.

These kinds of innovations, especially the first four types, will result in significant effects on the fulfilment of the customers’ latent needs and their delight experiences.

7. The development of the innovation system

In order to raise the customers’ loyalty, the enterprises should develop the core capabilities with an innovation system. In view of the above, the prerequisite for developing such a system is been described. As such, this chapter proposes a systematic innovation development system based on the product/service value chain.

7.1. The framework of the innovation system

At first, the differences among improvement, reengineering, and innovation are established as shown in Figure 4 . Improvement is implemented on the existing processes, as some problems may have been encountered during the manufacturing process or the service delivery process. Continuous improvement is the key activity of the TQM system, its aim is to improve the quality of products/services and all the observed and or experienced bottlenecks on the processes. The final objective is to raise customer satisfaction [ 55 ].

Figure 4.

The framework of the innovation system.

Hammer and Champy asserted that improving solely the production system or service delivery processes may not result in significant business performance [ 56 ]. Sometimes it is needed to reengineer the critical processes, or to redevelop the provision systems based on customer voices. The latter applies in particular to key customer values which are difficult to fulfill by adopting the improvement actions, as shown in Figure 4 . Thus, the aim of reengineering is to create customers’ values, which are the critical factors of raising customer loyalty. Besides, reengineering also reaps the benefits including shorter delivery times of products/services (including lead time and production time), reduction of costs, and the effective utilization of resources.

Most companies develop and implement enterprise resources planning (ERP), customer relationship management (CRM), and supply chain management (SCM) simultaneously [ 57 ]. By integrating these systems, enterprises can exert excellent business’ performance and customer's loyalty. In order to effectively utilize these networks and their integrated systems, it is the author's view that companies should proceed with the necessary processes of reengineering. This in turn, may have an impact on the critical functional activities on a timely basis.

The utilization of high‐tech functions and the rapid application of the internet resulted in the change of customers’ purchasing behavior [ 58 , 59 ]. Customers now focus not only on the evaluations of price and functions; rather they also integrate quality with the perceived value [ 60 ]. It is the author's view that business systems ought to change and pursue innovation, speed, and quality if they want to satisfy the overall needs of customers and create new value.

Customer satisfaction may be termed as fulfilling their requirements and expectations. This, however, is not enough for delighting them and raising their loyalty. Performed research indicates that a number of customer's latent needs are never discovered and satisfied by enterprises [ 61 ]. Thus, the latter's competitive force is to probe the unmet customers’ latent needs. There are some new methodologies proposed by several researchers to pinpoint customers’ latent needs [ 62 ]. Once the latter are identified, companies ought to overcome bottlenecks and aim at developing and providing innovative products/services to satisfy customers’ latent needs and curiosity.

Eventually the customer will be set at the center of innovation. Thomke and von Hippel asserted that “tapping into customer innovation can certainly generate tremendous value, but capturing customer value is hardly a simple or straightforward work” [ 63 ]. The term “innovation” is usually considered as a process or a capability to create new ideas, and then develop the innovative products/services in order to meet customers’ unsatisfied latent needs [ 64 , 65 ]. In essence, the realization of “innovation” depends on the implementation of an innovation system, as shown in Figure 4 . This innovation system starts at the “mind” mining of the customer's latent needs and ends in the customer's value and response, and vice versa.

7.2. The transfer loop of innovation system

customer value, and

product functions.

integrated multifunctions,

curiosity satisfaction,

easy to use, and

good quality at an affordable price.

Each of the other three constructs also contains several items. These constructs and their involving items are shown in Figure 5 .

The features of “innovative products” will satisfy the “customer value” which is accentuated by good quality, delight, good experience, and extra value‐added features. In order for the companies to fulfill these characteristics, it is hereby suggested to use “mind mining” methods to identify customers’ unsatisfied and latent needs. They also ought to use methods and means to eliminate the inconvenient utilization, and to integrate product functions and quality. These findings and results may be hereby included into the quality functions. For realizing these quality functions, the drivers are the capability of “technology innovation.” As such, the four constructs form a “transfer loop of the innovation system,” as shown in Figure 5 .

8. Conclusion

In a highly globalized economy, it is widely recognized that “innovation” has become the key force for achieving business excellence, which in turn reflects as competitive advantages, growth, and development [ 66 ]. Only the pursuit of product quality and service quality is not enough to achieve the business objectives. The enterprises should alter their quality concepts from the narrow definition of quality to include customer value and innovation. In order to realize the innovation performance, this study has proposed a framework of the innovation system and the related transfer loop of the system. However, the proposed system is a conceptual model, empirical studies ought to be conducted to identify potential causalities among the critical constructs and their practices.

Quality control is like a silent hero in our daily lives . It’s all about making sure the stuff we use – like food , gadgets , or even the roads we drive on – are really good . It checks everything from how things are made to how they work , to be sure they meet super high standards . So, even though we might not always realize it, quality control is always working behind the scenes to make sure everything is top-notch .

To understand the essence of Quality Control, its significance, the various types of Quality Control, and the numerous career prospects within this field. Check out the article given below:

Table of Content

What is Quality Control?

Types of quality control, quality control tools, quality control: processes and principles, significance of quality control, quality control vs. quality assurance, quality control: careers.

In simple words, Quality control is a process that makes sure things are good enough to use . It involves checking products and services to make sure they meet certain standards . This could mean making sure a toy is safe for kids to play with, or checking that a car is built correctly and works properly . Quality control helps make sure things are made well and are safe for people to use. It’s like having a team of inspectors who make sure everything is up to scratch before it gets to you.

Imagine you make clothes . You want each piece to be really good – no holes , the right size , and the colors just right. So, you check them carefully before they’re sold. That’s Quality Control (QC) . It’s like a special check to make sure things are good enough before they’re sold.

There are several types of Quality Control (QC) methods used to ensure that products and services meet specific standards. Some common types include:

1. Statistical Quality Control (SQC)

Statistical Quality Control (SQC) is a way of keeping track of quality using numbers and stats . It helps businesses make sure their products or services are good by monitoring them with statistical tools . SQC helps to catch any problems early by watching how things are made and comparing them to set standards . It’s like having a team of detectives who use math to spot any issues in the production process before they become big problems .

2. Acceptance Sampling

Acceptance Sampling is a quality control method where random samples are inspected from a batch to determine its quality . Instead of checking every item, only a portion is tested. If the sampled items pass inspection , the entire batch is accepted ; otherwise, further action may be taken. It’s a practical way to ensure quality without examining every single item.

3. Total Quality Control (TQC)

Total Quality Control (TQC) means everyone in a company works together to make sure everything is really good . It’s about always trying to make things better and keeping customers happy . TQC involves everyone , from bosses to regular workers , in finding and fixing problems , making sure things work well , and making the company better overall. It’s like a team effort to make sure everything is top-notch .

These tools are essential for analyzing and improving processes, identifying potential issues, and ensuring high-quality standards are maintained throughout production

These processes and principles serve as essential frameworks for ensuring consistent quality, minimizing defects, and continuously improving operations to meet customer expectations effectively.

The significance of Quality Control lies in its ability to ensure that products and services meet high standards before reaching customers . By implementing Quality Control measures, businesses can:

• Ensure Customer Satisfaction : By delivering high-quality products, businesses can satisfy their customers, leading to customer loyalty and positive word-of-mouth .
• Maintain Reputation : Consistently delivering products that meet or exceed customer expectations helps businesses maintain a positive reputation in the market.
• Reduce Costs : Quality Control helps identify and correct defects early in the production process, reducing the need for rework or waste , which can ultimately save businesses money.
• Comply with Regulations : Many industries have regulatory requirements regarding product quality and safety. Quality Control ensures that businesses meet these standards and avoid penalties or legal issues.
• Drive Continuous Improvement : Quality Control processes provide valuable feedback that can be used to identify areas for improvement in production processes, leading to ongoing enhancements and efficiency gains.

Overall, Quality Control plays a crucial role in ensuring that businesses deliver products and services that meet or exceed customer expectations, ultimately contributing to their success and sustainability in the market.

Quality Control (QC) is like checking your homework to make sure all the answers are right before you hand it in. It’s about finding mistakes and fixing them.

Quality Assurance (QA) is like studying and practicing so you’re really good at your subjects and don’t make mistakes in your homework in the first place. It’s about making sure you’re doing things right from the start to avoid errors.

What is Quality Assurance?  

Quality Assurance (QA) is a systematic approach that ensures that the processes used to create and deliver a product or service are well-defined, consistent, and capable of meeting the specified requirements. It is like setting up a recipe for baking a cake and ensuring that you follow that recipe strictly every time. The goal of QA is to prevent mistakes or defects from occurring in the first place. Quality Assurance involves various elements, such as the following: 

a) Adhering to standardised processes and procedures  

b) Training employees to be skilled and knowledgeable  

c) Conducting regular audits and assessments  

These are done to ensure that everything is going as per the plan of the organisation. It helps to produce high-quality products or services consistently. As a result, it leads to happier customers and a strong reputation for the organisation.  

Quality Assurance process   

Discussed below are some of the key elements of the Quality Assurance process: 

a) Process standardisation: QA teams work to define, document, and standardise the procedures, workflows, and best practices involved in production or service delivery. Standardisation gives clarity and consistency, reducing the chances of errors and variations. 

b) Documentation and training: QA involves the creation and maintenance of comprehensive documentation that gives an idea of processes, guidelines, and quality standards. Employees are trained to read and follow these documented procedures. It ensures that all are on the same page when it comes to quality expectations.  

c) Auditing and assessment: Regular audits and assessments are conducted to evaluate the extent to which processes adhere to established standards. Auditors review the documentation, observe the execution of tasks, and collect data to assess process effectiveness and identify areas for improvement.  

d) Root cause analysis: When deviations from quality standards are identified, QA processes delve into root cause analysis. This means identifying the basic reasons for quality issues and taking necessary actions to address these issues at their source.  

e) Customer feedback integration: Customer feedback plays a vital role in QA processes. Customer complaints and suggestions are analysed and integrated into the process. 

f) Risk management: QA also involves identifying and managing risks that could impact the quality of the product or service. By proactively addressing potential risks, QA helps prevent quality issues. 

What is Quality Control?  

Quality Control, often abbreviated as QC, is a systematic and methodical process. It ensures that the products or services an organisation produces meet specific quality standards. It involves the following: 

a) Examining  

b) Testing 

c) Inspecting 

Its primary goal is to ensure that what the customer receives is of the highest possible quality, free from any flaws or defects. 

Quality Control process  

Quality Control process involves a series of systematic steps and methods to identify and rectify defects or deviations. These are discussed below:  

1) Inspection: Inspection is a fundamental step in QC, where products or services are carefully examined to identify any visible defects from established standards. This step ensures that what is being delivered is in good condition and meets quality expectations.  

2) Testing: Testing involves subjecting the product or service to various assessments to verify its functionality, performance, and adherence to specific requirements. Testing may include performing the following: 

a) Functionality tests 

b) Stress tests 

c) Performance tests 

3) Statistical Process Control (SPC): SPC is a method used to monitor and control processes by collecting and analysing data during production. This data helps identify variations and trends that could lead to quality issues, allowing for timely corrective action. 

4) Sampling: Sampling is a technique where a sample of products or services is selected from a larger batch or production run for inspection or testing. This approach is often used to assess the quality of a large number of items efficiently.  

5) Quality data collection : During the QC process, data related to the quality of products or services is collected and documented. This data can include defect rates, measurements, and any other relevant information that helps evaluate quality. 

Corrective action: Once defects or quality issues are identified, appropriate corrective measures are taken to address them. This may involve repairing or reworking the product, modifying the service, or other necessary actions to ensure quality compliance.

Difference between Quality Assurance and Quality Control  

Quality Assurance vs Quality Control are two critical components of Quality Management, each with distinct roles and objectives. So, let’s look at the key differences between both in detail: 

Quality Assurance is primarily concerned with optimising the processes and systems responsible for producing products or services. Its main objective is the prevention of defects and errors by ensuring that these processes are clearly defined, standardised, and consistently capable of delivering high-quality results.  

QA achieves this by establishing guidelines, best practices, and standards to enhance the overall efficiency and effectiveness of operations. It is a proactive approach, actively addressing potential issues before they manifest during production, thereby reducing the likelihood of defects.  

By focusing on continuous improvement and process refinement, it minimises the need for extensive corrective measures after production. This makes QA an integral part of ensuring consistent quality throughout the production process. 

In contrast, Quality Control is centred on the final products or services. It is a reactive approach focused on detecting and addressing defects in the end results. QC involves the inspection, testing, and measurement of individual products to ensure they meet established quality standards. Unlike QA, QC's emphasis is on identifying and correcting defects rather than preventing them. 

QC occurs after the production process and is the last line of defence to ensure that the product or service meets the required quality level. While it is essential for identifying and rectifying issues, it can be more resource-intensive and costly compared to QA. It is costly as it involves dealing with problems that have already occurred.    

Thus, the key distinction lies in their roles. QA prevents defects by improving processes, while QC detects defects in the final product or service.

The integration of Quality Assurance and Quality Control  

The integration of Quality Assurance and Quality Control is an approach that organisations must use to build a robust Quality Management framework. It involves combining the strengths of both QA and QC to ensure that products or services not only meet predefined quality standards but also consistently exceed customer expectations. Here's how the integration of QA and QC works:  

a) Setting quality standards: The integration begins by establishing clear quality standards that define what constitutes a high-quality product or service. These standards serve as a common reference point for both QA and QC.  

b) Prevention and detection: QA focuses on preventing defects before they occur by optimising processes, while QC is primarily concerned with detecting defects in the final product or service. Integrating these approaches means actively working to prevent issues while also having robust systems in place to address any issues. 

c) Documentation and training: The integration ensures that the documentation developed and training given to the employees in QA are effectively utilised in QC. QC teams follow the documented procedures, ensuring that everyone understands and follows the quality expectations. 

d) Process optimisation: QA identifies areas where processes can be improved, standardised, and made more efficient. These enhancements reduce the likelihood of defects, lowering the need for extensive corrective actions in QC. 

e) Data sharing: QA and QC processes generate valuable data that can be shared and analysed together. This data sharing allows organisations to identify trends, predict potential issues, and take proactive measures. 

Conclusion  

We hope this blog helped answer the question: Quality Assurance vs Quality Control – which one is better? Their differences highlight that they are two different processes essential for ensuring the quality of a product or service. Quality Assurance prevents quality issues through defined processes and continuous improvement, while Quality Control detects and rectifies defects in final output. Integration of both these processes helps in creating customer satisfaction.

Five Ways to Improve Quality Control in Manufacturing

• By Cory Kyle
• May 10, 2024

Quality control matters. And there’s no other industry where this is more clear than manufacturing.

Quality control matters. And there’s no other industry where this is more clear than manufacturing. Other businesses may care about quality too. However, few businesses are as close to the results of their products as manufacturing. That means that the quality of their products is the difference between success and failure.

Why quality control matters

Manufacturing is a highly competitive industry. As a result, the only way to get customers and keep their business is through the quality of your products. This means making sure that what you produce is better than your competitors. Easier said than done. Your competitors are also doing everything possible to produce outstanding products. If you want to keep up, your business needs to be able to quickly identify product weaknesses and repeatedly produce high-quality products. That’s where quality control enters the picture. Quality control does more than just ensure you produce high-quality products. It gives you the control you need to keep making high-quality products.  

What is quality control?

But what actually is quality control? It’s easy to think of it as nothing more than a way to ensure your products meet a certain level of standard. However, that’s only one way to make use of quality control. Quality control also allows you to deeply study your manufacturing chain. Knowing where things are breaking down means being able to fix the problems. More importantly, it means being able to improve the manufacturing chain. These minor improvements can easily serve as a strong foundation for future improvements.  

Five ways to improve quality control in manufacturing

1. Study your manufacturing chain. Your manufacturing chain is the heart of your company. To have an effective quality control system in place, you need to know every aspect of how you assemble your products. Understanding this process is essential in being able to optimize and improve the final product. Likewise, having a deep understanding of the process allows you to find ways to streamline and raise the level of quality of your manufacturing chain. The only way to ensure quality control does its job is by having a strong foundation already in place. 2.  Properly train your employees. No matter how effective your quality control system is, it’s useless without skilled employees. Properly training your employees is essential in manufacturing. Things are no different when it comes to quality control. Your employees need to be able to identify and resolve the problems that your quality control system exposes. Not only that, they also need to understand why it’s important to focus on quality control. And the closer your employees are to the actual production chain, the more important it becomes. Furthermore, having properly trained employees makes it a lot easier to change things in the future. 3. Make use of statistics. One of the strongest strengths of quality control is the versatility of how you can implement different systems. Using statistics, for example, is a great way of improving the final result of your products. Acceptance sampling or quality control charts, for example, are easy to implement and provide a strong form of quality control. These and other methods that utilize statistics are usually cheaper and easier to implement than more traditional inspection methods. What makes statistic-based quality control great, however, is that there are methods that focus on the end product as well as the actual processes. 4. Regularly test your systems. One of the best ways of improving quality control is to make sure that your equipment is performing effectively and optimally. One of the most useful ways to check that your equipment is working at 100% is through randomized testing. By holding unscheduled tests, quality control can be measured, as well as how effectively employees are following safety protocols. As a result, the importance of employee safety can be reinforced throughout your workforce. Aside from improving the safety of your employees, these random tests also help to improve how well your employees can efficiently do their jobs. 5. Understand which methods work best. Because quality control contains many different methods, it’s essential that you understand which method is best for your specific manufacturing process. Perishables like food, for example, require a 100% inspection method in order to comply with many stringent regulations. However, the nature of this method makes it highly expensive. Knowing which quality control method is best suited to your business is essential.  

Better quality control leads to better products

When it comes to manufacturing, the quality of the final product is the cornerstone of any business. By improving your quality control, you ensure that the products you produce are worth your customer’s time and money. By spending the extra resources necessary to improve your quality control, you open up the path to continued success.

What is Statistical Quality Control?

• Neelam Tyagi
• Aug 26, 2021

Basic Terminologies

Statistics: Statistics means data, a good amount of data. Or simply, the collaborative study of accumulation, analysis, interpretation and presentation of massive volumes of data.

“Statistics are valuable representations of data that assist in the analysis and decision making process”

Statistical tools: Applications of statistical methods in order to visualize, interpret and anticipate outcomes over collected data.

Quality “ a characteristic of fitness for purpose at lowest cost” , or “degree of perfection that suffices the customer requirements”. Quality can be defined as “the entirety of features and characteristics for products and services satisfying implicit and explicit demands of customers. 

Control: An approach of measuring and inspecting a certain phenomenon for a product or a service, control suggests when to inspect, and how much to inspect. The system includes feedback to understand the causes for poor quality and necessary corrective steps. The control system basically determines the quality characteristics of an item, correlates the same with predefined quality standards and distinguishes between defective items from non-defectives ones.

Quality control: Quality control is one of the most important tools deployed to check the definite level of quality of products, or services. In todays’ highly competitive business environment, quality control has evolved as a prominent tool and a critical factor via any successful industry to ensure standard quality. In 1982, Peters and Waterman recognized quality as a crucial element in the virtue of excellence. 

(Related blog: Types of statistical analysis )

Therefore, quality control is the employment of appropriate techniques and activities in order to accomplish, sustain and upgrade the quality of products and services and to satisfy customer’s needs in terms of price, safety, availability, reliability, usability, etc.

The method employs statistical techniques based on probability theory to establish standards of quality and uphold it in the most economical manner. ( From )

Let’s understand the technique of applying statistical methods for quality control systems.

Statistical Quality Control (SQC)

Employing a number of statistical methods, SQC validates the quality of premium goods and services. In 1924, Walter A. Shewhart produced the basic ideas for statistical quality control, since after the area of SQC has been scattered its foundation with extensive work of researchers, quality controlled philosophers and statisticians. 

Making use of statistical tools and techniques in order to monitor and manage product quality across various industries including food, pharmaceutical and manufacturing units, the process is named as Statistical Quality Control. The method can be conducted as 

A part of production process, 

A part of last-minute quality control check

A part of eventual check by quality control department

“Statistical quality control can be simply defined as an economic & effective system of maintaining & improving the quality of outputs throughout the whole operating process of specification, production & inspection based on continuous testing with random samples.” -YA LUN CHOU

Statistical quality control techniques are extremely important for operating the estimable variations embedded in almost all manufacturing processes. Such variations arise due to raw material, consistency of product elements, processing machines, techniques deployed and packaging applications. Moreover, any of these factors or combination of two can impact the eventual quality of finished product. 

The method incorporates legislation allowing manufacturing units to make sure that the finished product must contain the net quantity mentioned in packaging. Any overfilled quantity can lead to financial loss for the manufacturer and therefore must be avoided. Fill control, validating weight and weight variation are hugely deployed statistical quality control techniques that make use of weights of individual products in the statistical data analysis .

In case of pharmaceutical goods, such as tablets, pills, capsules, syrups etc, the standard weight must not be exceeded the upper limit that saves consumers from taking high doses of active ingredients that might result in severe consequences. At the same time, the weight shouldn’t be too less, if not the drug might not be effective. In this case, the weight variation based statistical quality control test is used to ensure the consistency of the dosage unit, and also to support product identity, reliability and quality. 

Another example would be, in the production of food and beverages, it is required to inspect the weight of packages rendering quick confirmation such that filled quantities fulfil the legal necessities. Any deviation from standard value signifies errors in the production process, imprecise ingredient-quantities leading to impactful consequences.

In addition to this, while confirming consumer satisfaction, safety and compliance with regulations, SQC with weight determination is highly important. Though, it is recommended to employ actual balances or measuring scales and software suitable for particular applications.

(Must read: Statistical data distribution models )

For example, SQC serves as a medium allowing manufacturers to attain maximum benefits by following controlled testing of manufactured products. Using this procedure, a manufacturing team can investigate the range of products with certain values that can be expected to reside under some existing conditions. The information is precisely validated for a number of similar products and be informed to the producer and the purchaser. 

In addition to this, the information determines compliance with specifications and looks at whether the manufacturing process/unit is capable of producing products within its unit. Also, if existing specifications are unable to meet the end outcome or economically unacceptable, then quality control data is helpful in providing minimum criteria for developing the improved standards.

(Suggested blog: Sampling distribution )

Advantages of Statistical Quality Control

One of the excellent scientific tools, SQC has the following advantages;

Cost reduction: In this method, only a fragmentary output is inspected to ensure the quality of product, therefore probe cost would be reduced greatly. 

Huge efficiency: Inspection of a fractional portion requires lesser time and tedium in comparison to holistic investigation leading to huge escalation in efficiency and production. 

Easier to use: Pitching SQC not only reduces process variability but also makes the process of production-in-control. Even, it is much to apply by an individual without having such extensive specialized guidance.

Authentic anticipation: SQC is the most preeminent approach that can accurately predict future production. To ensure the degree of perfection and product performance, SQC provides a great predictability. 

Prior fault detection: Any deviation from standard control limits depicts signs of danger in the underlying production process that invites necessary corrective measurement to be taken earlier. SQC is helpful in early detection of faults. 

While in holistic inspection, unnecessary fluctuations under quality control process would be detected in the final stage, but for the time being numerous defective items have already been produced. 

In such conditions, SQC (using chart controls) enables a pictorial view of how the production process is performing and where curative steps must be accounted for for smooth functioning of the process. ( Source )

SQC vs SPC  

Both SQC and SPC support smooth operations in order to escalate efficiencies, desired output and optimized performance while playing a key role in overall success in operations, but in different ways. Lets’ understand the difference;

SPC: is the procedure of collecting and computing parameters of a process such as speed, pressure, vernier caliper etc with respect to standard values using various statistical methods validating values must reside within limits while aiming to minimize variation and execute to achieve desired/optimum targets.

SQC: is the process of compiling and determining data on the subject of particular specifications regarding a product and to meet requirements, for example, size, weight, texture etc. while aiming at validating process outcomes to meet the user requirements or the next stage of the manufacturing process.

SPC is responsible for reduction of variation in processes and run efficiently, in contrast to this, SQC facilitates manufacturers to accomplish user requirements. 

For example, in food and beverage manufacturing there are various numbers of different products being produced, SPC monitors that operations are executing effectively at their entirety, SQC controls measurable quality characteristics used during production so that finished products must live up with customer requirements/expectations.

(Read also: Data types in statistics )

“Statistical quality control should be viewed as a kit of tools which may influence decisions to the functions of specification, production or inspection. -EUGENE L. GRANT

SQC has turned out to be a vital platform as a business operation that is deployed to enhance productivity and sustain competitive advantages. The method reflects a systematic approach of efficient statistically-oriented experimentation particularly in terms of characterization, optimization, sample acceptance along with ensuring active determination/inspection of deployment process with respect to real-world applications.

Conclusion & Further Reading

At a glance.

Concluding the CDC's best practices for environmental cleaning procedures in global healthcare settings.

The materials on this page were created for use in global healthcare facilities with limited resources, particularly in low- and middle-income countries. Environmental cleaning resources designed for U.S. healthcare facilities can be found at Healthcare Environment Infection Prevention .

The importance of environmental cleaning as a fundamental IPC intervention cannot be overstated. Environmental contamination plays a role in transmission of HAIs, which are a significant burden globally and disproportionately affect those in resource-limited settings.

The best practices contained in this document provide the framework for implementing effective environmental cleaning procedures and programs in healthcare facilities in resource-limited settings. While they are structured to be most relevant for resource-limited settings, implementing all the best practices for cleaning supplies and equipment, cleaning procedures, and, most importantly, for cleaning programs will require a strong and sustained commitment, including dedicated staff time and resources. Strong leadership support for environmental cleaning and recognition of the important role that it plays in IPC is a critical prerequisite to implementing these best practices.

It is important that environmental cleaning is implemented within the framework of a functional IPC program, while ensuring that a multi-sectorial approach is taken to enable engagement and coordination across the various sectors (e.g., WASH) that have a role to play to ensure a functional and effective cleaning program.

A toolkit for guiding the implementation of these best practices is currently under development. It will use the step-wise approach that IPC improvement programs use extensively. It will also address the need to prioritize actions that target the highest transmission risk based on environmental contamination and patient vulnerability, as well as the foundational program elements which are needed first in order to build an effective and robust environmental cleaning program over time.

Background and purpose Timely identification of Local Failure (LF) after stereotactic radiosurgery offers the opportunity for appropriate treatment modifications that may result in improved treatment outcomes, patient survival, and quality of life. Previous studies showed that the addition of either radiomics or deep learning features to clinical features increased the accuracy of the models in predicting Local Control (LC) of brain metastases after stereotactic radiosurgery. To date, however, no study combined both radiomics and deep learning features together with clinical features to develop machine learning algorithms to predict LC of brain metastases. In this study, we examined whether a model trained with a combination of all these features could predict LC better than models trained with only a subset of these features.

Materials and methods Pre-treatment brain MRIs and clinical data were collected retrospectively for 129 patients at the Gamma Knife Center of Elisabeth-TweeSteden Hospital (ETZ), Tilburg, The Netherlands. The patients were split into 103 patients for training and 26 patients for testing. The segment-based radiomics features were extracted using the radiomics feature extractor of the python radiomics package. The deep learning features were extracted using a fine-tuned 3D ResNet model and then combined with the clinical and radiomics features. A Random Forest classifier was trained with the training data set and then tested with the test data set. The performance was compared across 4 different models trained with clinical features only, clinical and radiomics features, clinical and deep learning features, and clinical, radiomics and deep learning features.

Results The prediction model with only clinical variables provided an Area Under the receiver operating characteristic Curve (AUC) of 0.82 and an accuracy of 75.6%. The prediction model with the combination of clinical and radiomics features demonstrated an AUC of 0.880 and an accuracy of 83.3% whereas the prediction model with the combination of clinical and deep learning features demonstrated an AUC of 0.863 and an accuracy of 78.3%. The best prediction performance was associated with the model that combined the clinical, radiomics and deep learning features with an AUC of 0.886 and 87% accuracy.

Conclusion Machine learning models trained on radiomics features and deep learning features combined with patient characteristics show good potential to predict LC after stereotactic radiosurgery with high accuracy. The promising findings from this study demonstrate the potential for early prediction of stereotactic radiosurgery outcome for brain metastasis prior to treatment initiation and might offer the opportunity for appropriate treatment modifications that may result in improved treatment outcomes, patient survival, and quality of life.
