What is the cost of quality? Does it raise the price of goods and services? Are huge
savings possible by implementing continual improvement efforts? These questions are
not easy ones, but quality is measureable, as are its costs. Philip Crosby, in Quality
is Free, writes that the cost of quality is "the expense of noncomformance - the
cost of doing things wrong." Some prefer the term "cost of poor quality" (COPQ) because
that implies what happens when continual improvement efforts are derailed or postponed.
As A.V. Feigenbaum, an early writer on the subject states in Total Quality Control:
Today, we not only recognize the measurability of quality costs but that these costs
are central to the management and engineering of modern total quality control as
well as to the business strategy planning of companies and plants.
