Review before build
DFM and DFA review before tooling, with a clear answer on what the process can hold.
Sourcing
Whole-BOM purchasing from authorised channels, incoming inspection and life-cycle checks.
Test and records
Test coverage matched to the product, plus lot traceability so a claim can be resolved from records rather than opinion.
After the build
Ask how rework is documented and who investigates field returns. The answer says more about the supplier than a factory tour.
