The cost or act of fixing defects or defectives as to make them fit for use in accordance with either the customer requirements or internal specifications, and the like. These costs and/or acts sometimes includes extra operations created to solve an entire lot of defects or defectives.

The goal of all quality plans should encompass rework in an effort to circumvent such activities. One goal of six sigma is to reduce rework to zero.

Rework is always a non-value adding activity.
