Again we break the Cost of Good Quality calculation into two different terms: Appraisal Costs (AC) and Prevention Costs (PC).Īppraisal Costs are the costs associated with measuring, evaluating or auditing products or services to assure conformance to quality standards and performance requirements. Generally, these are the costs companies incur to ensure they are producing quality products. When it comes to the Cost of Good Quality, these are the costs that are much less likely to be measured by a company. This can be understood by the following equation:ĮFC = Returned Product Costs + Warranty Costs + Product Recall Costs To give this part of the equation more structure, we think of Poor Quality costts as having two different terms: Internal Failure Costs (IFC) and External Failure Costs (EFC). Examples would include scrap, rework, and returned materials. These are the traditional quality costs companies measure.
Let's start wit the Cost of Poor Quality.
This can be understood in the below formula: Cost of Good Quality and Cost of Poor QualityĪt the highest level, there are two different terms in the Cost of Quality equation: the Cost of Good Quality (CoGQ) and the Cost of Poor Quality (CoPQ). To remedy these shortcomings, we thought building on one of our favorite definitions (provided by ASQ, an organization we respect and support at LNS Research) would be a good starting point for this post.

Often these definitions have not kept up with the times and don't account for software costs, supply chain interactions, or more. There are many different definitions of the Cost of Quality available, and many are lacking in scope or precision. However, we neglected to give a formal Cost of Quality Definition.

In that post we also took a deep dive into how to measure and gain business value from the Cost of Quality metric. In a recent blog post on Enterprise Quality Management Software, we examined how measuring and minimizing the Cost of Quality (CoQ) was one of the many benefits of EQMS.
