Quick answer: Change a defined variable while preserving identifiable material, geometry and measurement conditions.

How should a forming trial be organized?
Changing several settings and material lots simultaneously makes improvement difficult to explain or reproduce. Record the intended hypothesis and all settings relevant to comparison. Keep unsuccessful samples because they often show the mechanism of a defect.

A practical verification method
Compare matched sample groups and confirm the observed change persists under a repeated trial.
| 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 matched sample groups and confirm the observed change persists under a repeated trial. | 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.
