Zero Defects (or ZD) was a management-led program to eliminate defects in industrial production that enjoyed brief popularity in American industry from 1964 to the early 1970s.
Zero Defects was first introduced by American businessman, Philip Crosby, in his “14 Step Quality Improvement Process”. Since then, a number of manufacturing organizations have employed it to tackle and improve quality issues. Zero defects is referred to as a philosophy, a mentality, or a movement which is aimed at minimizing the number of defects in manufactured products and service as much as possible. It is often considered as having no distinct steps to follow or rules to abide by, which leaves companies open to customising how they want it to work for themselves.
