How to Conduct an Effective Internal Audit: Tips for Non-Auditors

Internal audits are a vital part of maintaining and improving your management systems, whether for ISO 9001, ISO 14001, ISO 45001, or other standards. But if you’re not a professional auditor, the thought of conducting one can be intimidating. The good news? Internal audits don’t have to be complex or daunting — with the right approach, anyone can carry out an effective audit that adds real value to their organisation.

At AlineX, we work closely with businesses across Tamworth and beyond to provide tailored support and training, including helping non-auditors develop the confidence and skills to run internal audits smoothly. Here are some practical tips to get you started.

1. Understand the Purpose of the Audit

Before you start, remember that the goal of an internal audit is not to “catch” people out or find faults but to check how well your processes meet the requirements of your management system and identify opportunities for improvement. It’s a positive and constructive activity, aimed at strengthening your business.

2. Know Your Audit Scope and Criteria

Clarify what part of your system you’re auditing. Are you focusing on quality processes, environmental controls, health and safety measures, or a specific department? Knowing exactly what to look for will keep your audit focused and manageable.

Review the relevant standards, procedures, and previous audit reports to understand the expectations and common issues.

3. Prepare a Simple Audit Checklist

You don’t need to create a complicated document. A checklist based on key points from your procedures and ISO requirements helps you stay organised and ensures you don’t miss important areas. AlineX can help you design bespoke checklists tailored to your specific business.

4. Observe, Ask Questions, and Collect Evidence

During the audit, observe how activities are carried out, ask open-ended questions, and look for records or documents that demonstrate compliance. Evidence can include physical observations, documents, interview responses, or data records.

Remember to remain objective and professional — you’re gathering facts, not making assumptions.

5. Take Clear, Concise Notes

Good notes are essential for your audit report. Record what you saw, heard, and reviewed. Be factual and avoid opinions. Note any positive findings as well as areas that may need improvement.

6. Communicate Clearly and Respectfully

An internal audit is a two-way conversation, not a grilling. Keep communication respectful and supportive to encourage openness. If you find issues, frame them as opportunities for improvement rather than faults.

7. Report Your Findings Effectively

Your audit report should summarise what you audited, what went well, and any non-conformances or observations. Include clear recommendations or actions where necessary. AlineX offers support in writing and presenting audit reports to ensure clarity and professionalism.

8. Follow Up on Actions

An audit doesn’t end with the report. Ensure that any corrective actions are assigned, tracked, and completed. This closes the loop and drives continual improvement in your organisation.
