Drawing on quality… Expand Cost of Poor Quality (COPQ) is the cost associated with providing poor quality products or services to the customer. In other words, it is the total financial losses incurred by the company due to performing incorrect things. For example, scrap, rework, repair, warranty failure. Cost of Quality is a methodology used in the organization to measure the amount of resources being used for the cost of good quality. In other words, it is the cost of achieving quality products or services. Cost of quality is the combination of cost of good quality and cost of poor quality. Why Cost of Poor Quality (COPQ)
Categories of Cost of QualityCost of quality can be divided into four categories: prevention cost, appraisal cost, internal failure cost, and external failure cost. Preventive Cost– Preventive costs are the costs of the activities specially designed to prevent poor quality of products or services. In other words, efforts are related to preventing failures.
Appraisal costs – Appraisal costs are the costs incurred due to those activities which are performed to detect the poor quality of product or services. In other words, appraisal costs are related to testing, measuring, and auditing. The appraisal cost focuses on the discovery of defects rather than the prevention of defects.
Internal failure – Internal failure costs result from the identification of defects prior to delivery of the product or service to the customers. In addition, these are the costs due to the failure of a product to achieve required quality standards.
External failure – External failure costs arise from the rejection of the product or services by the customers after delivery. In other words, these are the costs when a product or service fails to meet the required quality standards and is detected after it reaches the customer.
When to use Cost of Poor Quality (COPQ)Organizations use COPQ to understand the opportunities to improve the quality by reducing internal and external failure costs. Basically, by increasing the expenditure on prevention. Steps in implementing Cost of Poor Quality (COPQ)
Example of Cost of Poor Quality (COPQ)Quality assurance is everything for an organization. Incorporating Six Sigma and other Lean tools, this allows companies to decrease waste (Raw materials, Logistics costs, and unnecessary man hrs) which increases their bottom line. Let’s say you are running a DMAIC project. In the define phase, you want to quantify the cost of poor quality. You start by defining what a defect is, then measuring how many defects per million opportunities your process has. (You would use this same material to create your baseline sigma in the measure phase, next.) Example: Imagine producing TVs and for every 1M produced 2% were damaged… That’s 20,000 TVs. If those damages were not salvageable, and it cost $100 to produce each unit, then it cost your company 20k *$100 = $2 Million But that’s not all. How many people would you work on re-inspection, warranty repair, supplier evaluation etc.? Here you go for the breakup of the costs. Below are the split-up of various costs (Just as an example). Total material cost is $100 unit and an additional $10 per unit spent on quality costs. At 20k units, that is $200k. The total cost to the company would be $2.2 Million!

Why Pursue a Six Sigma Level of Quality / Excellence?Let’s use the same example. At a Six Sigma level you would only produce 3.4 defects per million opportunities. In the previous example the process was making 20,000 defects per million. Moving to a six sigma level of quality would mean 19,996.6 less defects per million units made! That’s a savings of $2.2M – (3.4 * $110) = $2.2M – $374 … so, nearly $2.2 Million! Avoid ErrorsThe best in any field figured out how to avoid errors very early on. We should, too, if we want to engineer a great process.
