Quick answer: Conditions can change over the run, and the pilot should reveal relevant start, middle and end behavior.
Why sample more than the first pilot parts?
Early samples may reflect setup rather than sustained production. Choose locations based on the process and expected variation, and preserve sequence identity. A convenience sample of only the best-looking parts gives weak evidence.
A practical verification method
Compare identified samples across the run for dimensions, output and the defects under investigation.
| 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 | Compare identified samples across the run for dimensions, output and the defects under investigation. | 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.
