The purchasing decision
Ask each supplier to identify the exact model and included accessories. Separate sample evaluation, recurring unit cost and any stocking arrangement. A cheaper assembly with an unresolved control interface is not an equivalent quotation.
Keep these records
- Common configuration and quantity.
- Included accessories and evidence.
- Exceptions requiring review.
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.
