Overview
This governance and evidence record defines the scope and buyer use of Prototype and NPI Support. It distinguishes source-qualified company evidence from representative context, private records, expired documents, and claims still requiring approval.
Engineering review matrix
Each row links a design variable to evidence that can support a drawing or release decision.
| Variable | Control question | Verification route |
|---|---|---|
| Record ownership | For Prototype and NPI Support, drawing, specification, material, program, traveler, inspection, certificate, deviation, and release records need owners and revisions. | Audit the link from requirement through output and disposition. |
| Change boundary | Customer, supplier, material, tooling, program, method, equipment, site, and process changes need risk review. | Record affected items, reason, approval, validation, effective lot, and containment. |
| Lot identity | Incoming lots, work order, split/merge, rework, samples, packaging, and shipment must remain reconcilable. | Perform backward and forward trace using a controlled sample. |
| Evidence scope | A photo, certificate, report, checklist, or equipment record supports only its controlled scope. | Verify validity, relevance, method, result, redaction, and permission. |
| Buyer handoff | RFQ assumptions, deviations, inspection output, labels, documents, and retention must be agreed. | Review the shipment or service pack against purchase and release requirements. |
Governance route
The order makes assumptions and ownership visible before a result is promoted to a requirement.
- 01
Identify the buyer decision
For Prototype and NPI Support, document the functional requirement, operating boundary, interfaces, quantities, and acceptance owner against the current drawing.
- 02
Select the controlling record
For Prototype and NPI Support, compare the applicable material and process routes, recording compatibility limits, trade-offs, and verification needs before selection.
- 03
Verify scope and validity
For Prototype and NPI Support, agree the inspection method, sample plan, acceptance criteria, traceability, and report format before validation.
- 04
Redact protected information
For Prototype and NPI Support, remove customer identity, confidential geometry, drawing data, lot codes, and other protected information while preserving technical traceability.
- 05
Release with ownership and revision
For Prototype and NPI Support, close remaining assumptions and link the quoted or released scope to the drawing revision, evidence set, owner, and change-control plan.
Failure controls
These are review prompts, not evidence that every risk applies or that every test is available.
- A
Revision mismatch across customer files, artwork, program, traveler, and inspection
- B
Unapproved substitution or process change escaping review
- C
Trace break at lot split, rework, subcontract, packaging, or shipment
- D
Evidence reused outside date, product, method, organization, or legal scope
Inputs for a practical review
Unknown values may be labelled unknown. The review should convert uncertainty into an explicit decision or validation task.
