Reporting a quality deviation
The report has one job: make the investigation possible. Containment happens in parallel, not afterwards.
Containment first
What is affected — batch, lot or serial range, with the boundaries stated · where that material is now, including anything already shipped · whether it is on hold · whether the process is stopped.
Then the record
What was observed against what was specified, with the measurement and the tolerance · when detected and by whom, by role · how detected — inspection, in process, or by the customer · the traceability chain back to material and supplier.
The boundary question
How far back does it go? The last known-good check defines the suspect window, and if it cannot be established, say so — that is a wider recall, and hiding it is worse.
Never
Record a cause. "Operator error" as an entry ends the investigation before it starts, and the cause is almost never the operator.
