The purchasing decision
Agree the critical dimensions, report format and sample identification before ordering. Separate dimensional conformance, assembly fit and any required performance evaluation. Resolve deviations in writing before placing a repeat batch order.
Keep these records
- Ballooned drawing or characteristic list.
- Measured results tied to sample IDs.
- Disposition of every deviation.
Give each record an owner and a revision or date. If a supplier proposes a different part or test condition, record it as an exception for review before treating the quotation as equivalent.
Turn the review into a sourcing request
Start with the linked component checklist, add the actual platform and part identity, and state quantity, destination and timing. List unresolved requirements explicitly so the first discussion can focus on those gaps.
