Inspection Narrative Map

Problem addressed

Validation packages can contain many documents while leaving the core decision difficult to explain.

Limitation of existing practice

Document-centric summaries list deliverables but do not show why the evidence is sufficient.

Proposed method: inputs and steps

1. State the intended use.
2. Name the material failure.
3. Identify the controlling mechanism.
4. Point to representative evidence.
5. Explain residual risk and approval.
6. Show continued monitoring and change response.

Decision outputs

• One-page narrative
• Evidence index
• Question-ready rationale

Worked example

For a LIMS–ERP interface, the narrative connects lot-result transfer risk to schema controls, exception queues, reconciliation evidence, and daily monitoring.

When to use—and when not to

Use when: Preparing validation summaries, periodic reviews, leadership decisions, and inspections.

Do not use as-is when: As a replacement for the underlying evidence.

Limitations

A concise map may oversimplify if its linked evidence is not accessible.

Inspection questions

• Can the owner explain the decision without reading a document list?
• Where is the weakest link?
• What changed since approval?
