Cost of Poor Quality - A Detailed Guide

Understanding Cost of Poor Quality and Ways to Reduce it 


Are you in the process of accessing quality information regarding the cost of poor quality? Six Sigma offers a way to assess the costs of poor quality. Costs of Poor Quality, also called COPQ, is used for a better workplace organization.


Cost of quality and price of poor quality is defined as the methodology that allows an organization to detect the extent to which its resources are used for the activities that help prevent the quality issues. It describes the process to determine the size to avoid poor quality and appraise the organization's product or service quality. It can be the result of internal and external failures. But having this information allows the workplace organization to determine the potential savings gained by implementing process improvement.


Whenever the detection of error is immediate, the cost can be typically minor, but when the detection of error takes a long time, it can cost more than expected. The best thing about it is that the repair doesn't involve much disassembly or the multiple departments often present. Nevertheless, there is certain cost of poor quality formula that helps to calculate accurate results.


Costs of Poor Quality: An overview


Before going further, let's explore the term costs of poor quality. The costs of poor quality can be defined as the direct and indirect costs that are mainly associated with the defects generated by the entire process. The cost can vary according to the situation. If we talk about cost reduction, it can also depend on how far the product or the service goes during the long process before being determined. It is essential to consider the concept of COPQ in six Sigma definition to access better results and opportunities. These costs can be easily calculated with the help of requirements. To calculate the costs of poor quality, you need to determine the criteria to be repaired and what was impacted within the main process flow when time and resources had to be spent on the repairs. Make sure to follow the criteria to get accurate results. This COPQ definition is worth keeping in mind.


Generally, it is essential to discuss the worst possibility. When the case gains the worst option with the defects that can make customers disappointed, then it is the time when the costs increase exponentially. You may also need to consider professional help and service for better repair and repair of the defects at the customer's location. It is vital to learn how to determine and differentiate between cost of good quality and cost of poor quality.


Now let's talk about some cost of poor quality examples to understand better. We know that there are actual costs related to the direct reworking of the product, like reduction of error rates that can decrease work. It is essential to know that there are a lot of indirect COPQ examples that are important to consider for better results. Most design costs are like making changes in the design to eliminate any error in the future. Most of the expenses are resourcing costs similar to taking resources from different design projects to detect defects. If we talk about the worst loss, it is brand recognition, including the possibility of the customer going to the competition. Make sure to prefer the COPQ formula to get accuracy in the results. There are many other cost of poor quality calculation examples as well. It would be helpful to learn about this concept with the help of examples of cost of poor quality.


What are the reasons to attend Costs of Poor Quality?


The primary motive of the costs of poor quality is to implement the continuous improvement process if the significant lost opportunity cost to the business failure. The second motive of these tools is to rank the rate among all other success metrics. It is essential to learn that six Sigma and lean six Sigma mainly revolve around the issue or quality. To calculate the costs of poor quality we can put six Sigma into action. Most of the time, COPQ is calculated during the phase of the definition of a DMAIC project. COPQ calculation is essential for a better manufacturing process. Use the correct cost of poor quality calculation formula in your workplace organization.

Here are the benefits of COPQ that you should know.


  • Reduces overall cost


The best thing about it is that it helps to reduce the total cost. If you can detect the error or the defects sooner of any specific products and services, you will have to spend less amount to repair. Similarly if you see the flaws at the end of the production process, it may be cumbersome to disassemble the product and reach the defects. This can cost more. It is essential to detect the defects early to reduce repair costs. If the imperfections make it to the customer, then it is more expensive, and it will include the higher possibilities of eroding the customer's confidence in the brand.


  • Reduce the lead time


If we talk about the most significant advantage, it helps reduce the lead time. When you can detect the product or service error sooner, the faster you can perform the repair. When you find the defects at the end of production, you may need additional time and new resources. The costs of poor quality helps to detect the error sooner to reduce the lead time. When the defects are found at the customer, you will have to give more time to repair, and the product may be sent back.


  • Satisfied customers


It is no hidden fact that every business or organization is required to fulfill customers' expectations. In that case, the cost of poor quality in manufacturing helps to satisfy your customer most effectively. We all know that no one wants to waste time dealing with brands that provide poor-quality products. In addition it will help you detect the rate issue related to customer delivery. This will help fulfill customers' requirements by providing the best experience.


Best Practices to Lower COPQ


Certain things are essential to learn before proceeding. These will help you determine cost of quality and cost of poor quality.


  • It is highly recommended to remember that the quality initiative will always minimize the defects. However, it is rare to reach zero defects over a specific time. Therefore, it is essential to put the proper process to help you identify the error as soon as possible to reduce the costs. You may have to deal with the additional verification costs, but those costs will be far less than the error costs that go undetected until the lengthy process.
  • It is also suggested that if the new products have been moved into process or production early and are experiencing multiple or even critical defects issues, you need to take immediate action to assign the personnel required to deal with the defects before moving with future projects. If you don't prefer immediate action, you may have to face significant risks related to the cost of repair and your customers' reputation.
  • It is no secret that it can be very challenging to calculate all the individual hard and soft costs connected to the COPQ in quality for the project. It would help if you were as exact as possible or as your data allows you to be. You need to take any burden off the data. You make sure to keep the goal of understanding the ballpark savings. Generally, actual savings will never match your estimated savings for the specific project if the improvement has been proceeding in the play at a particular time.

What are the different types of costs?


It is the cost that is mainly associated with poor quality or services. It has three categories which are the following:


  • Appraisal costs


The cost of poor quality six Sigma is incurred to determine the conformance to the quality requirements. The appraisal costs are associated with measuring and monitoring the quality activities in context of appraisal costs. They may include the following-


  • Verification by checking the incoming material requires setting up the process and product against agreed specifications.
  • It also includes quality audits by confirming that the quality system is correctly working.
  • Supplier ratings hold other values, and it requires the approval of suppliers of products and services.


These cost of poor quality definition play an essential role. They are associated with the supplier and the customer evaluation of the purchased materials process to ensure they conform to the specifications.


  • Internal failure cost


Internal failure costs are incurred to remedy defects discovered before the product, or the service is delivered to the clients. They may include the following.


  • It can include waste like the performance of unnecessary work or holding out the stock due to an error with poor organization and communication.
  • Many defective products or materials are worthless and cannot be repaired anymore or even sold.
  • It also includes the correction of the defective material or the errors.
  • The analysis of failure is the activities required to establish the causes of internal product or service failure.


These costs appear when the results of the failure of work reach design quality standards and are mainly detected before the transfer to the customer.


  • External failure costs


If we talk about the external failure costs incurred to remedy defects discovered by the customer, they could include the following:


  • Repairs and servicing are included in external failure costs for both returned products and those in the field.
  • It may consist of warranty claims when the failed products are replaced or the services are re-performed under guarantee.
  • Complaints are associated with the handling and servicing of the customer's criticism.
  • Returns are also included in the external costs as it provides for handling and investigating rejected or recalled products and service. It also consists of the costs of transportation.


COPQ lean six Sigma mainly appears when the product or service fails to reach the quality of design standard and cannot detect the defects until after the development and service transfer to the customer.


  • Prevention costs


These costs are vital for every workplace organization. These costs help prevent further charges due to faults and errors. Prevention costs mainly happen to prevent and avoid the issues related to quality. The prevention costs are also associated with the design and maintenance of the quality management system. The best thing about this cost is that it is planned and incurred before the actual operations. They could include the following.


  • Prevention costs incur the costs of products and service requirements. This is associated with establishing the specifications for the incoming material with the process and finished product.
  • This can include the costs of planning quality. However, it is essential to lead a successful business. It creates a quality purpose, reliability, operation, and inspection plan.
  • Quality assurance is also included in the prevention costs that involve creating and maintaining the quality system.
  • Training costs are also in the list of prevention costs for the program's development, preparation, and maintenance.


The Objective of Cost of Poor Quality


We have discussed almost everything related to costs of poor quality. But now we will explore more about its objectives. This will help you better understand this concept in your workplace to access more profitable outcome results.

 A quality job is crucial for the workplace organization to avoid any complaints or defects that lead to poor reputation and low growth level.

COPQ analysis or cost of poor quality analysis provides an effective process to assess the effectiveness of quality management, and it also means that it determines the problematic areas and opportunities.


It is essential to know that the cost of quality is as high as the communication tools. Therefore, when there is the establishment of the quality costs system, it should become more dynamic and needs to have a positive impact on the achievement of the organization's mission and as per the goals and objectives of the organization as well.




When the specific part of the service moves on to a different department, it becomes more expensive to repair and fix. In that case, there will be more requirements for disassembly. You may also need multiple personnel with more time and coordination. Still, if we talk about the cost of finding errors at this point, then it is manageable. However, it cannot be preferred to immediate identification. There is no hidden fact that the cost of poor quality metrics and the coordination increase whenever the problem is undetected until right before hand-off to the customer in the most effective way. You can also expect to see the repair costs skyrocket. Knowing how to assess these costs is a key part of running any service in any sort of industry.
