# Design Verification Plan and Report (DVP&R) ## When to use Use this skill when: - Creating a DVP for a new part design during APQP Phase 2 - Reviewing a supplier's DVP for completeness and DFMEA alignment - Determining which tests are required for a specific failure mode or design characteristic - Tracking test completion and recording results (the "R" in DVP&R) - Assessing whether a design change requires additional validation testing ## Prerequisites - DFMEA with all failure modes identified and AP ratings assigned - Engineering drawing with all characteristics defined - Customer design specifications and performance requirements - List of applicable standards and test methods (customer spec, ISO, SAE, etc.) ## Workflow ### Step 1 — Understand the DVP structure The DVP&R is a table with one row per test. Each test must address at least one failure mode or design characteristic from the DFMEA. **The linkage rule:** Every H-AP (High Action Priority) failure mode in the DFMEA must have at least one corresponding test in the DVP. If a failure mode has no test, document why (e.g., analysis-only justification with sign-off). ### Step 2 — Build each DVP row | Column | What to enter | |--------|--------------| | Test number | Sequential reference (e.g., DVP-001) | | DFMEA reference | Failure mode number(s) this test addresses | | Test name / description | Specific name of the test (not "durability test" — use "salt spray 240h per ASTM B117") | | Test specification | Sta...
