UNDERSTAND THE CONCEPT
An out-of-tolerance result raises a question about the instrument and about prior decisions that depended on it. Record the as-found condition before adjustment where the approved process requires it, and preserve the calibration evidence.
A qualified review should consider the affected time window, measurement use, uncertainty and potential impact. Do not assume every prior result is invalid or that a successful adjustment resolves the historical question. Document disposition and corrective follow-up through the applicable quality process.
Questions to take back to your team
- Is the as-found evidence preserved?
- Which prior decisions could be affected?
- Who owns the documented impact assessment and disposition?
