RFQ and technical guide
Marked Drawing Substitution RFQ: Request a Controlled Comparison
A substitution RFQ works when the original condition is visible beside the proposed change. Ask the supplier to identify downstream checks instead of simply naming an alternate material. No equivalence, price or timing claim is made; the response must establish what remains to be checked.
For buyers who need a supplier to propose an alternate construction.
Define the buyer decision
Marked Drawing Substitution RFQ: Request a Controlled Comparison answers one buyer question: Request a controlled substitution comparison with original and proposed drawings, affected dimensions and approval questions. Confirm scope and evidence before relea. In this marked drawing substitution rfq brief, define original detail, proposed change and review impact as the controlled object and write the user-facing outcome beside it. Keep nearby style, panel or shipment details separate; the opening line should tell a supplier whether the requested answer concerns appearance, interaction, counting or documentation.
Mark the reference and revision
The working record for marked drawing substitution rfq is a comparison drawing and response checklist. Put the style identity, orientation, revision and viewing state on that record, then point to the original detail, proposed change and review impact. Any hidden face, neighboring seam, carton line or source measurement that was not supplied belongs in an open-items field. That makes the reference usable by design, production and receiving without implying that the proposed route is already accepted.
Separate approval from proposal
For change control, send the two states together and ask for a scoped response. Compare the approved input with the proposed route and write the difference in the same file. Preserve the original condition, the proposed condition and the reviewer who must answer about the original detail, proposed change and review impact. Treat the supplier receives a generic request and returns an untraceable alternative as the recheck trigger. A feasibility response can guide the next sample or RFQ, but it is not an automatic equivalence decision.
Review the real interaction
Review marked drawing substitution rfq at the handoff where the decision will be used. Put the original detail, proposed change and review impact beside the risk question — the supplier receives a generic request and returns an untraceable alternative — and use the completed garment, receiving record or marked drawing that a buyer will actually inspect. Ask a second reviewer to locate a comparison drawing and response checklist without a private explanation. Record the observed state and the unresolved edge separately; one attractive view cannot stand in for every size, color, material or shipment group.
Keep the evidence boundary visible
The evidence boundary is explicit: No equivalence, price or timing claim is made; the response must establish what remains to be checked. This article supplies a buyer planning route, not a factory profile or laboratory result. If additional price, timing, certification, stock, tolerance or performance confirmation is needed, request it for the exact configuration shown in a comparison drawing and response checklist. When that configuration changes, open a new decision line instead of carrying forward an old assumption.
Close the loop before release
Close the marked drawing substitution rfq brief with a response that names the original detail, proposed change and review impact, the revision reviewed, the evidence retained and the next owner. State whether the item is approved, open or replaced, and link the answer to a comparison drawing and response checklist. The goal — resolve the original detail, proposed change and review impact decisions before approval — is met only when another reviewer can repeat the check and see which part remains to be confirmed.
Decision and evidence checklist
| Decision | Include in the brief | Review evidence |
|---|---|---|
| Decision focus | the original detail, proposed change and review impact | Named reference and intended result |
| Working record | a comparison drawing and response checklist | Revision, owner and observed evidence |
| Open boundary | the supplier receives a generic request and returns an untraceable alternative | Explicit confirmation before release |
What this brief does and does not establish
This article is a buyer planning brief for the original detail, proposed change and review impact. It does not establish a factory capability, certification, price, lead time, universal tolerance or performance result. No equivalence, price or timing claim is made; the response must establish what remains to be checked.

Buyer questions
What should the brief identify first for the original detail, proposed change and review impact?
Start with the original detail, proposed change and review impact, the intended outcome and a comparison drawing and response checklist. For this marked drawing substitution rfq brief, keep the supplier receives a generic request and returns an untraceable alternative as an explicit question until the responsible reviewer confirms it.
Does a drawing or quote approve the original detail, proposed change and review impact automatically?
No. A drawing or quote records a proposal for the original detail, proposed change and review impact; approval follows the defined review of a comparison drawing and response checklist and the observed result. The file should still show what remains open.
What should happen if the proposed route changes the original detail, proposed change and review impact?
Keep the original reference, request a marked comparison and repeat the check linked to the supplier receives a generic request and returns an untraceable alternative. Record who owns the response and do not describe the change as equivalent without project evidence.
