Internal audits are a key part of maintaining ISO certification and improving business processes. They help organisations identify issues, track performance, and stay compliant with international standards. In this blog, we explain how to conduct effective internal audits, the key steps involved, and how Irish and UK businesses can use auditing to meet ISO requirements and drive improvement.
What Is an Internal Audit?
An internal audit is a systematic process used to review whether an organisation’s systems and processes meet the requirements of a specific ISO standard. It helps confirm that procedures are being followed, identifies gaps or risks, and provides evidence for continuous improvement.
Internal audits are required for most ISO standards, including:
- ISO 9001 (Quality Management)
- ISO 14001 (Environmental Management)
- ISO 45001 (Health and Safety Management)
- ISO 27001 (Information Security Management)
- ISO 50001 (Energy Management)
Why Do Internal Audits Matter?
- Support ISO Certification
Internal audits are a requirement for maintaining ISO certification and preparing for external audits. - Identify Non-Conformities
Audits highlight areas where processes do not meet ISO requirements or internal procedures. - Promote Continuous Improvement
Findings from audits help businesses refine operations, reduce risk, and improve efficiency. - Increase Employee Awareness
Audits involve staff and raise awareness of how processes support quality and compliance. - Ensure Legal and Regulatory Compliance
Audits help identify where legal requirements may not be fully met, reducing exposure to penalties or reputational harm.
What Are The Steps to Perform an Effective Internal Audit?
1. Plan the Audit
Define the audit scope, objectives, criteria, and schedule. Use your audit plan to assign responsibilities and ensure coverage of all relevant processes.
2. Review Documentation
Examine relevant policies, procedures, and previous audit findings. This helps the auditor understand what should be happening before evaluating actual performance.
3. Conduct the Audit
Use checklists and gather evidence through observation, interviews, and document reviews. Record both compliance and any non-conformities found.
4. Report the Findings
Prepare a clear audit report that outlines what was reviewed, what was found, and any corrective actions needed. Include both strengths and areas for improvement.
5. Follow Up on Actions
Assign responsibility for corrective actions and verify that improvements have been made. Monitor progress and close out actions when complete.
6. Review and Improve the Audit Process
Evaluate how the audit was conducted and identify opportunities to improve the process for future audits.
Common Internal Audit Mistakes to Avoid
- Auditing without a plan or clear criteria
- Failing to remain objective and independent
- Not following up on corrective actions
- Ignoring input from relevant employees
- Overlooking smaller non-conformities
