T1 Sample Defect Map

A buyer review workspace for converting scattered T1 observations into finding IDs, evidence requests, owners, closure status, and a documented approval decision.

T1 Sample Defect Map: Buyer Approval Risk Explainer

A T1 review is stronger when every visible, dimensional, functional, and documentation finding is mapped to a sample, cavity, location, severity, owner, and next action. The buyer should not approve from a few good-looking samples while open findings remain scattered or undocumented.

Static review summary: map every T1 finding to a sample, cavity, location, severity, owner, evidence request, and approval condition before releasing production.

Step 1: What the buyer receives

Start by identifying every sample, cavity, revision, material, and trial condition before judging approval readiness.

Step 2: Map each finding

Map cosmetic, dimensional, functional, tooling, and documentation findings rather than discussing them as a loose list.

Step 3: Compare by cavity

Per-cavity differences may change the approval risk and the evidence needed before release.

Step 4: Assign severity and owner

Separate observation from disposition: every open item needs an owner, evidence request, and approval condition.

Step 5: Connect evidence

Require traceable evidence so each approval decision can be linked to the actual sample and finding.

Step 6: Review closure

A supplier statement that an item is fixed is not the same as buyer-reviewed verification evidence.

Step 7: Approval decision

Delay approval when critical findings, evidence gaps, ownership, or closure criteria remain unresolved.

This buyer-side explainer is a review framework, not a substitute for engineering, quality, or supplier approval procedures. The significance and disposition of each T1 finding should be verified against the actual drawing, specification, samples, tests, process record, and agreed approval requirements.
