Quick answer: Document ownership and permitted use of drawings, calculations, tooling-related information and supplied samples.
What rights should be clarified for a custom design?
Paying for parts does not automatically settle every design-rights question. Clarify what can be transferred to another supplier and what remains confidential. These are commercial terms requiring an agreement, not assumptions derived from a technical drawing.
A practical verification method
Check the written agreement for each deliverable's use, transfer and confidentiality scope.
| 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 | Check the written agreement for each deliverable's use, transfer and confidentiality scope. | 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.
