Vendor Quality Assurance Auditing

Service summary

An evaluation of the arrangements a vendor uses to prevent and control quality failures. The audit examines how specifications, process controls and acceptance decisions are applied to the products or services supplied.

The service provides buyers with a clearer understanding of the vendor’s assurance practices. Findings address the evidence examined and do not replace incoming acceptance checks or guarantee the conformity of unexamined deliveries.

Key objectives

• Assess specification-to-control alignment
• Examine inspection and release discipline
• Evaluate nonconforming-output controls
• Identify weaknesses affecting supply consistency

Methodology

Selected products or service outputs are traced through the vendor’s quality controls, with evidence tested at key acceptance and release points.

• Define supplied outputs, specifications and quality assurance criteria.
• Review quality plans, inspection instructions and relevant competence records.
• Select representative orders, outputs and nonconformity cases.
• Observe process checks and interview quality and operational personnel.
• Trace inspection results, acceptance decisions and authorised release records.
• Evaluate handling of deviations, concessions and recurring quality concerns.
• Report evidence-based quality assurance findings and their scope.
