Quick answer: Provide the controlling revision, acceptance method, sample approval scope, traceability requirements and applicable handling instructions.
What should accompany the approved spring into production?
Knowledge held only in prototype emails is easily lost. Link the final technical decisions to the procurement and assembly records. Clearly identify assumptions still awaiting confirmation so they are not mistaken for approved specifications.
A practical verification method
Trace the handover package through a representative production order and confirm each required document is available.
| 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 | Trace the handover package through a representative production order and confirm each required document is available. | 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.
