A chronological record of every inspection event, result, and data change, providing clear proof for buyers.
An audit trail records who performed an action, when it happened and what changed. It helps teams reconstruct an inspection decision; it does not by itself prove that every defect was detected.
Record the change
Keep the user identity, timestamp, affected record and previous and new values. Record a reason when results are corrected or a lot is approved again. Link supporting photos and measurements where relevant.
Protect the history
Restrict changes to or deletion of the log. During a review, compare events with the inspection report and approval record. A last-updated timestamp is not a complete audit trail.
Key takeaways
- Keep who, what, when and why with the change history.
- A log supports investigation; it is not a guarantee of product conformity.
