The Cost of Quality (CoQ) represents all costs related to maintaining product quality, including prevention, appraisal, and failure costs.
Cost of Quality is a technique defining and measuring where and what amount of a companies’ resources are being used for prevention activities and maintaining product quality as opposed to the costs resulting from internal and external failures.
Six Sigma lets you work out the cost of quality by estimating:
If there are litigations and fines, then they add up to the costs as well and can bring a business on its knees. So while it is hard to say how much it costs to make a quality product, it is easier to calculate how much it will cost a company that neglects quality.

Reducing the Cost of Quality (CoQ) is essential for manufacturers both from a regulatory perspective and to keep manufacturing costs…
The economic environment is becoming increasingly more competitive. Many companies are promoting quality as the core customer value and consider it to be a key success factor for achieving competitiveness. There are various alternatives available to the customer for almost every product on the market. The better-performing companies set themselves apart by listening to the voice of the customer and supplying products according to the customers’ requirements while maintaining a high level of quality and dependability. These companies gain their advantage by measuring and reporting the cost of quality (COQ).
The Cost of Quality can be portrayed by the sum of two factors, the Cost of Good Quality (COGQ) and the Cost of Poor Quality (COPQ).
COQ = COGQ + COPQ
The Cost of Quality incorporates all associated costs with the quality of a product, from preventive costs intended to reduce failures, cost of process controls to maintain quality levels, and the costs related to both internal and external failures.
The efficient utilization and implementation of the Cost of Quality technique enable an organization to assess the number of resources being used for the Cost of Good Quality and the Cost of Poor Quality. With this crucial information, the organization can determine where to allocate resources to improve product quality and the outcome.
Cost of Quality calculation differs from organization to organization. Many times, organizations determine the Cost of Quality by calculating total warranty dollars as a percentage of sales. But this method looks externally at the Cost of Quality and not internally. For better understanding, a more comprehensive overview of all quality costs is essential.
The cost of Quality is categorized by:
By applying these four categories to the original Cost of Quality equation, which states that Cost of Quality is the sum of Cost of Good Quality and the Cost of Poor Quality, the basic equation can be expanded as shown below:
By combining the above equations, the Cost of Quality can be more defined, as shown below:
COQ = COGQ+ COPQ = (PC + AC) + (IFC + EFC)
Signify the costs incurred with the efforts taken to prevent the occurrence of defects. Prevention Costs imply the following:
Represent the costs incurred with inspected tests and performed checks to determine whether the particular requirements are met. Appraisal costs can include the following:
Describe the costs incurred to rectify all the nonconformities found before the product supply to the recipient. Internal failure is determined by the following:
Depict the costs incurred to correct all the nonconformities found after the product supply to the recipient. External failure costs indicate the following:
The Taguchi Quality Loss Function (QLF) is a statistical function, proposed by the Japanese quality expert Genichi Taguchi, which states that the quality loss function is used to estimate costs when the product or process characteristics are switched from the target value. This is represented by the following equation:
L= k(y-T) ^2 where L= Quality loss
y = the actual size of the product
T = Target value
k = Proportionality constant.
This is also known as parameter design, which is a selection of a parameter level to make the process robust against environmental changes with the smallest variation.
Customer Success
The Cost of Good Quality (CoGQ) represents investments made to prevent poor quality and ensure high-quality products and services. It includes costs associated with:
Prevention Costs: Incurred to prevent defects and errors before occurrence, examples include quality planning, training, process improvement, and preventive maintenance.
Appraisal Costs: Associated with evaluating and verifying product and service quality, examples include inspection, testing, and quality audits.
The Cost of Poor Quality (CoPQ) denotes the financial setbacks incurred by a company resulting from subpar products or services. It encompasses all expenses tied to errors, defects, and inefficiencies throughout the production and delivery process.
Categories of CoPQ:
Internal Failure Costs: These expenses occur before the product reaches the customer and encompass scrap, rework, reinspection, and warranty claims.
External Failure Costs: These costs arise after the product reaches the customer and encompass returns, repairs, product recalls, lost customer satisfaction, and legal liabilities.
High COPQ Quality or Cost of Poor Quality in manufacturing can significantly affect the business in several ways:

There are several ways of perceiving the Cost of Quality while they can be contradictory towards each other.
Reduce Quality Costs and Boost ROI
Your business is transformed in many ways to reduce costs across every level of your manufacturing operations if the quality is embedded within every operation. With a quality manufacturing approach, the cost of quality initiatives become a powerful tool to improve return on investment.
Reduce the cost of waste, scrap, and rework
Relying solely on a final inspection for quality control can be too late. If a process differs from specification anywhere in the production line, that finished product goes directly to the waste bin, accumulating the incalculable costs in rework and materials. You must monitor product and process quality in real-time at every critical operation so that plant operators can adjust and eliminate variations before they cause costly waste.
Turn customer complaints into customer satisfaction
When you can identify and rectify product and process variations early before your final inspection and reach to customers or if customers are having issues or concerns, then you should provide immediate access to reporting for responding to customer queries quickly. This can build a stronger bond, more repeat orders, and better customer relationships.
Build brand equity and gain a competitive advantage
Extensive data collection and quality control analysis capabilities, automated alerts, and aggregated access to historical data enable unparalleled product consistency to meet your customers’ expectations and elevate your brand as the premium producer in your industry.

Total Cost of Quality represents the sum of Cost of Poor Quality and Cost of Good Quality, offering a comprehensive view of the total cost associated with quality in an organization. Analyzing Total Cost of Quality helps identify areas for improvement and prioritize quality initiatives for maximum return on investment.
