A quality audit is a systematic, independent examination of a quality system to determine whether quality activities and related results comply with planned arrangements. It identifies areas for improvement and ensures compliance with standards and regulations.
Three main types: First-party audits (internal) conducted by the organisation itself. Second-party audits conducted by a customer on a supplier. Third-party audits conducted by an independent certification body.
Preparation includes: defining the audit scope and objectives, reviewing relevant documents and standards, preparing checklists and audit plans, selecting qualified audit team members, and scheduling the audit with the auditee.
During the audit: conduct opening meeting, review documentation, observe operations, interview personnel, collect objective evidence, record findings (non-conformances, observations, opportunities for improvement), and hold the closing meeting.
After the audit: issue the audit report, develop corrective action plans for non-conformances, assign responsible parties and deadlines, implement corrective actions, verify effectiveness of corrections, and close audit findings.
