What is Cost of Quality (COQ) - CoQ = CoGQ + CoPQ

Appraisal Costs

Ever had a conversation with your boss about how costly the food safety and quality management systems are? As food safety and quality professionals, we are often ill-equipped to have these financial discussions.
Well, perhaps you need to introduce the Cost of Quality thinking. Then you can talk your boss’ language


There is Cost of Quality is a methodology used to define and measure where and what amount of an organization’s resources are being used for prevention activities and maintaining product quality as opposed to the costs resulting from internal and external failures. The Cost of Quality can be represented by the sum of two factors. The Cost of Good Quality and the Cost of Poor Quality equals the Cost of Quality.


By measuring these costs, you will soon see if where the problems are. Investing in the Cost of Good Quality does not necessarily mean that the overall Cost of Quality will increase. In fact, when the resources are invested in the right areas, the Cost of Quality should decrease. When failures are prevented/detected prior to leaving the facility and reaching the customer, the Cost of Poor Quality will be reduced.
