Quality Audits

What this topic covers

Systematic evaluation of whether quality processes are defined and followed.

Core testing ideas

Audits compare evidence with planned arrangements and requirements.

Audit independence and competence improve credibility.

An audit finding should lead to documented action and closure.

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.
