Cost of quality (also known by its acronym, COQ, as well as as costs of quality and quality costs; hereinafter, the Costs) is two parts of all the costs incurred to ensure quality. These two parts are:

  1. Cost of good quality (also known as costs of conformance), which are money spent to avoid failures or, in other words, to keep produced marketables defect-free. They include prevention and appraisal costs.
  2. Cost of poor quality (also known as failure cost, costs of non-conformance, or costs of failure of conformance), which are money spent because of failures or, in other words, of failure of keeping produced marketables defect-free. They include tangible and intangible internal (i.e. before the marketable reaches the customer) and external (i.e. after the marketable reaches the customer costs.

The PAF paradigm addresses the same concept; PAF is the acronym for prevention, appraisal, failure. Economically, the cost of good quality and cost of poor quality should tend to be about equal.
