Prioritise the cause behind repeat defects
Combine audit findings, inspection records and complaints to identify recurring failure modes. Distinguish a capability gap from an unclear specification or material change. Agree a baseline before starting; otherwise a later improvement claim may simply reflect a different product mix or inspection scope.
Make the change observable
An action should describe what changes at incoming control, setup, assembly, testing or packing. Name the owner and evidence to retain. Revised work instructions, equipment checks and mistake-proofing can be reviewed at the process; the relevant measure is their effect on the identified failure mode.
Check implementation and sustained effect
Illustrative case: the supplier changes a fixture to prevent reversed assembly. Confirm the fixture is actually used, challenge the control safely under an agreed method and examine later batch records. Define review timing from risk and output, not a promised universal return on investment or fixed improvement percentage.
