CNFANS Guide: How to Track QC Exceptions Separately

2026-04-08

A systematic approach to logging unusual inspection failures for continuous improvement.

The Problem: Standard Logs Aren't Enough

In a typical Quality Control (QC) process, all failures—whether common or highly unusual—are often recorded in the same log. This makes it easy for critical, non-routine exceptions

The Solution: A Dedicated QC Exceptions Log

Create and maintain a separate, structured log exclusively

Key Elements of the Exceptions Log:

Data Field Purpose & Detail
Exception ID A unique tracking number (e.g., EX-2023-087).
Date & Time Precise timestamp of discovery.
Product/Batch # Specific item(s) affected.
Failure Description Clear, factual detail of the anomaly with photos if possible.
Severity Level Classify as Critical, Major, or Minor based on impact.
Root Cause Analysis Findings from investigation (e.g., "uncalibrated sensor," "atypical raw material batch").
Containment Action Immediate step taken (e.g., "batch isolated," "line stopped").
Corrective/Preventive Action Long-term fix implemented to prevent recurrence.
Action Owner & Due Date Accountability for implementing the fix.
Closure Status Track as Open, In Progress, Closed-Verified.
