Industrial Quality Assurance Systems

What this topic covers

Procedures, competence, audits, records and improvement used to create confidence in consistent quality.

Core testing ideas

QA controls how work is planned and performed rather than inspecting quality into a finished product.

Document control, competence and internal review support repeatability.

Testing evidence should feed corrective and preventive improvement.

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.
