RFQ & Program Launch
Prototype Cable Assembly RFQ Checklist
Prototype RFQs should show what is fixed, what is still open, and how the first build will be judged. Marked samples, early drawings, connector details, material questions, and test criteria keep prototype work from becoming guesswork.

Decision summary
What to carry into the decision
- Identify which dimensions, components, and tests are frozen and which remain open for the first build.
- Use a deviation and question list so a prototype does not silently become the production baseline.
- Define what will be measured, photographed, tested, and approved before ordering the next build.

Use the sections in sequence, then turn the open items into one controlled build or sourcing package.
Direct answer
Send the latest drawing or sketch, marked sample photos, connector details, open dimensions, material questions, required tests, prototype quantity, and next-lot expectation. State whether the prototype is for fit, function, validation, or production planning.
Prototype checklist
A prototype quote should identify uncertainty instead of hiding it.
- Fixed connector, terminal, wire, cable, pinout, label, and packing requirements.
- Open dimensions, material choices, tooling assumptions, and expected changes after review.
- Sample or drawing status, prototype quantity, schedule target, and later quantity expectation.
- Fit, function, continuity, visual, dimensional, or validation tests required for the first build.
First-build review
After prototype inspection, compare the sample against the drawing, photos, and test notes. Record approved changes before moving to the next lot so the build baseline stays visible.
Define the prototype decision
State whether the prototype is for fit, function, validation, or production planning, then record the review outcome and any changes before the next lot.
Prototype decision log
Keep the question, temporary answer, evidence, and final disposition together.
| Open item | Dimension, material, connector, routing, tooling, test, label, or packaging question. |
|---|---|
| Build assumption | The exact temporary value or method authorized for this sample. |
| Evidence | Measurement, photo, fit check, test result, or document used to judge the item. |
| Release action | Drawing or BOM update, approved deviation, repeat sample, or closed item with owner and date. |
Keep prototype and production records distinct
Mark sample-only substitutions, hand operations, temporary tooling, and incomplete packaging. If those differences matter to repeatability, close them before the production drawing and control plan are released.
