Industrial Certification Systems

What this topic covers

How product, personnel and management-system certifications differ.

Core testing ideas

Certification can apply to organizations, products, processes or people depending on the scheme.

Certification is different from laboratory accreditation and regulatory approval.

The issuing body's scope and recognition matter.

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.
