Meaning
Systematic log tracks every instance where a component or material does not meet the specified engineering standards. Maintenance of a non-conformance register is a mandatory requirement for most international quality certifications. The document follows the product from the arrival of raw materials through to final packaging.
Data Entry
Identifying a defect triggers an immediate entry that describes the nature of the failure and the location of the part. This non-conformance register functions as the primary evidence for process audits. Accurate records are necessary to distinguish between a minor cosmetic flaw and a major structural deficit.
Corrective Action
Engineers review the entries to decide if a part should be scrapped, reworked or accepted under a concession. The non-conformance register records the decision and the name of the person who authorized it. Following these steps ensures that no faulty material reaches the production floor.
Verification of the repair must be signed off by a second inspector to maintain the chain of custody. No batch can leave the factory until every open entry is closed.
Trend Observation
Periodic reviews of the log reveal if certain machines or shifts are producing more errors than others. A heavy non-conformance register indicates that the process is not yet stable enough for full production. Tracking these failures over time helps in calculating the true cost of quality.
