Quick answer: Link the observed symptom to evidence that supports a cause and explains why plausible alternatives were rejected.
What makes a root-cause conclusion reviewable?
A replaced part that restores function is useful evidence but may not identify the cause. Record controlled comparisons, physical observations and limits of the investigation. The corrective action should address the supported mechanism and include a check that the symptom does not recur.
A practical verification method
Review each hypothesis against the evidence, then validate the chosen corrective action under the original relevant conditions.
| 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 each hypothesis against the evidence, then validate the chosen corrective action under the original relevant conditions. | 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.
