Quality Problem Zeroing

Goal

Close a quality problem with objective evidence that:

1. Locates and explains the technical failure;
2. Removes every confirmed root cause and verifies the result;
3. Identifies and repairs management weaknesses where required;
4. Extends the learning to other exposed products, processes, and organizations; and
5. Leaves no action, evidence, approval, or known residual risk hidden at closure.

GB/T 29076—2021 is the controlling source for scope, sequence, terminology, and closure. Treat other methods and publications as supporting guidance only. Read the standard method guide whenever a formal scope decision, report, or closure review is required.
