Philip Crosby introduced the concept of zero defects and published Quality Is Free in 1979 after working in quality management for over a decade. The document summarizes Crosby's key ideas on quality including that quality is free through preventing defects, outlines a five stage Quality Management Maturity Grid to assess organizational quality practices, and presents a 14-step quality improvement program used by many companies to enhance quality. An example is given of a Chinese factory that successfully turned around its operations and financials by following Crosby's approach.
