Zero Defects | Glossary

Definition
Zero Defects is a Lean philosophy introduced by Philip Crosby, that aims to reduce and minimize the number of defects and errors in a process, in hopes of getting things right the first time. The primary aim of the process, is bringing down the level of defects to zero. This philosophy was highly derided, as it was found to put employees under a lot of pressure and reduced their creativity.

Origin
“Zero Defects Mentality” from the US Army, where no defects in an environment are tolerated.
