The Four Absolutes of Quality were developed by quality guru Philip Crosby as a way to promote the idea increased quality did not mean increased cost. Quality and cost were not in competition which he expanded on in his best-seller, “Quality Is Free.”

The Four Absolutes:

  1. Quality is defined as conformance to requirements
  2. The system for causing quality is prevention, not appraisal
  3. The performance standard must be Zero Defects
  4. The measurement of quality is the Price of Nonconformance
