Why build a requirements-to-evidence map?
The map prevents requirements from remaining scattered across contracts, drawings, quality clauses, source restrictions, test plans, security instructions, and program correspondence. It creates one visible chain from obligation to control to record to acceptance.
The map is not a substitute for the governing documents. It is an execution index. Each row should cite the controlling source, identify the affected product or activity, assign implementation and approval authority, name the evidence, and state when the evidence is reviewed.
Core production-control map
| Requirement category | Control question | Evidence category |
|---|---|---|
| Configuration | Which revision and software state are authorized? | Released baseline, effectivity, and change record |
| Source restriction | Which item or process is restricted, and by what authority? | Approved-source basis and country-of-origin evidence |
| Material | How is material identity preserved through the build? | Purchase, receipt, lot, cert, and consumption records |
| Process | Which work method and special controls apply? | Released instructions, qualification, and execution record |
| Inspection | What characteristic is checked, when, and by whom? | Inspection plan, result, instrument, and disposition |
| Test | Which test establishes function or acceptance? | Method, configuration, asset status, result, and approval |
| Nonconformance | How is unexpected product controlled and resolved? | Record, containment, disposition, and authority |
| Release | Who may accept and release the unit or lot? | Acceptance record and release packet |
How is the map built?
- Inventory controlling sources. Identify the contract, statement of work, specifications, drawings, clauses, approved plans, and formal program decisions that create obligations.
- Normalize the requirement. Restate each requirement without changing meaning, then identify the exact product, process, source, data, facility, or record it affects.
- Name the control. Specify the procedure, system, inspection, test, review, or approval that implements the requirement.
- Assign authority. Distinguish implementation owner, design authority, quality authority, customer approval, and final release.
- Name retained evidence. Define the record, identifier, retention location, relationship to the unit or lot, and review point.
- Expose gaps. Mark missing definitions, conflicting sources, unverified credentials, unavailable evidence, and approvals that remain open.
What makes the map trustworthy?
Every row needs source provenance, current revision, scope, an owner, and a review state. Broad labels such as traceable, domestic, compliant, qualified, secure, or accepted are not enough. The map should show what the word means for this program and which record supports it.
The public website should never display an actual customer map unless every visible fact is approved for release. A neutral template can teach the method without implying program experience or customer permission.
