Quick answer: Use appropriate measured data, a defined characteristic and a stable process with a valid analysis method.

What evidence is needed before calling a process capable?
A machine's nominal resolution is not process capability. Nor does one successful batch establish long-term behavior. State the population, measurement system and conditions behind the claim, and avoid unsupported capability numbers in customer-facing content.

A practical verification method
Review the actual data and method with the quality team against the applicable requirement.
| 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 | Review the actual data and method with the quality team against the applicable requirement. | 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.
