In standardized quality inspection processes, typical defects are routinely logged and addressed. However, unusual, complex, or high-impact failures
A general defect tracking system often buries critical anomalies. A dedicated log ensures: Not every minor failure qualifies. Establish triggers for the separate log, such as: Each log entry should capture more detail than a standard defect record. Recommended fields include: When an inspector identifies an exception, the process should be: The log is a tool, not an archive. Conduct monthly or quarterly reviews to: By diligently tracking QC exceptions separately, CNFANS builds a powerful knowledge base that: Each exception reveals a weakness in the standard process, allowing for continuous refinement. Historical exceptions provide immediate reference points for solving new, similar issues. Data-rich exception logs provide clear evidence for supplier quality reviews and negotiations. Turns individual problem-solving experiences into shared organizational knowledge.Why a Separate Exception Log is Critical
