Defect Rate is a material management KPI that shows the percentage of
the materials or products with defects to the total number of materials
supplied or products produced over some period of time. Any imperfection that results
in the impossibility to use this material or product in accordance with its
specification can be considered a defect. Defect rate can be found by the
formula:
Defect Rate = Total number of defects per project / Total number of defects
per project
