Nonconformance Management
Identify, segregate, review and disposition results that do not meet requirements.
What this topic covers
Identify, segregate, review and disposition results that do not meet requirements.
Core testing ideas
A nonconformance record should identify the requirement, evidence and affected product.
Disposition can include rework, repair, use-as-is authorization or rejection under controlled authority.
Root-cause and corrective action may be appropriate when problems recur.
Measurement and method limits
SPC and capability metrics describe process behaviour, while engineering specifications describe product requirements.
Evidence and traceability
Nonconformance, corrective action, audits and supplier controls close the loop when results do not meet expectations.
Using the result
Quality metrics should be defined consistently so improvement is real rather than a reporting artifact.
