01
Separate symptom from cause
A stain, size deviation or missing part is a symptom. Cleaning control, worn tooling, first-piece approval or packing count may be the cause.
02
Make action verifiable
State owner, due date, affected scope, rework quantity and verification method, supported by evidence.
03
Use trends to set control
Track recurrence by product, factory, process and defect type to decide on DUPRO, audit, sorting or training.
Use note
