Explain the function
Identify mating parts, important fits, and the surfaces that matter in use. Describe the problem you need to solve. If a requirement is still being developed, mark it for review rather than presenting it as final.
RFQ preparation
A better RFQ starts with the right information
A useful request for quotation connects the drawing to the way you plan to buy, approve, and receive the part. Give engineering and purchasing the same starting point so manufacturing assumptions can be resolved together.
Build one clear information package.
Identify the current revision and the document that governs acceptance. If a drawing, CAD model, or sample differs, flag the difference instead of leaving the supplier to choose. For an assembly, include the bill of materials and identify supplied or purchased components.
| Include | Clarify |
|---|---|
| Drawing & revision | Part number, CAD or print, material grade, finish, critical features, and applicable specifications. |
| Demand & timing | Prototype quantity, expected annual demand, order or release quantities, and required milestones. |
| Tooling & material | Existing tooling, ownership, available condition information, and whether raw material will be supplied. |
| Approval & delivery | PPAP expectations, inspection records, material certifications, lot traceability, labeling, packaging, and ship-to requirements. |
Separate requirements from open questions.
Show the whole program
A sample order and a production release can need different planning. Include the expected progression and any customer approval dates. K-O can review manufacturability, tooling, and connected operations against those needs.
Make comparisons meaningful
When reviewing quotations, compare the same revision, quantities, included operations, tooling scope, documentation, and packaging. Record any exclusions or assumptions so a lower piece price is not mistaken for an equivalent scope.
You can begin a discussion before every detail is settled. A short list of unresolved requirements is more useful than silently filling gaps with assumptions. Keep the agreed changes with the revision used for the order.
