Quick answer: Prioritize features whose later correction is difficult or whose variation changes retention, travel or output.

Which features deserve checks before final assembly?
Inspection at every step is not inherently useful. Select checks based on the failure path and manufacturing route. Define what happens when a result is outside limits so defects are contained before more work is added.

A practical verification method
Follow a sample through the route and verify that the chosen checks detect the identified failure conditions.
| Item | What to record | Purpose |
|---|---|---|
| Reference configuration | Part or assembly identity and drawing revision | Make comparisons traceable |
| Test conditions | Relevant position, direction and operating condition | Compare the same characteristic |
| Decision evidence | Follow a sample through the route and verify that the chosen checks detect the identified failure conditions. | Resolve the specific question before approval |

Use the result in an engineering request
Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
