Introduction
An ISO internal audit is an independent, planned assessment of your management system. It checks whether processes meet the applicable ISO standard, internal procedures, and organizational requirements, while also identifying opportunities for improvement.
Internal audits are essential because they give management early visibility of nonconformities before an external certification or surveillance audit. Internal auditor training commonly focuses on planning audits, identifying nonconformities, reporting findings, and supporting corrective actions
Purpose of internal audit
A well-planned internal audit helps organizations:
- Verify conformity with the selected ISO standard
- Confirm that procedures are followed in practice
- Identify process risks, gaps, and improvement opportunities
- Check the effectiveness of previous corrective actions
- Prepare evidence for management review
- Reduce the risk of major nonconformities during external audits
- Strengthen employee understanding of the management system
Internal audit process
- Prepare an audit programme: Define audit frequency, scope, criteria, auditors, and areas to be covered across the certification cycle.
- Plan each audit: Confirm objectives, criteria, departments, process owners, documents, records, and audit schedule.
- Prepare checklists: Use the ISO standard, internal procedures, legal requirements, customer requirements, and past findings to create relevant questions.
- Conduct the audit: Interview employees, observe activities, review records, and collect objective evidence.
- Classify findings: Identify conformities, observations, opportunities for improvement, minor nonconformities, and major nonconformities where applicable.
- Report results: Document audit scope, evidence, findings, conclusions, and required actions in a clear audit report.
- Support corrective action: Ensure responsible owners identify root causes, implement actions, and provide evidence of completion.
- Verify effectiveness: Confirm that corrective actions have resolved the issue and prevented recurrence.
- “Show me how this process is controlled.”
- “What evidence confirms this activity was completed?”
- “How do you recognize and manage nonconforming work”
- “What corrective and improvement measures have been implemented since the previous audit?”
- “How do you know this corrective action was effective?”
