Internal Audit
A planned, systematic review of a management system by the organisation itself.
ISO 19011 provides guidance on auditing management systems. Internal audits must be: planned (programme covering all processes and areas), competence-based (auditors independent of the area being audited), documented (findings, nonconformities, and opportunities for improvement), and followed up for corrective action closure. Results feed the Management Review.
