In short: Technical knowledge is only half the story. The best internal auditors combine curiosity, objectivity and excellent communication.
Internal audits are one of the most powerful tools in a management system — when they are done well. What separates a good internal auditor from a box-ticker?
1. Understanding the process, not just the clause
Good auditors follow the process approach: they look at inputs, activities, outputs, controls and results, and test how well they work together.
2. Objectivity and evidence
Findings must be based on verifiable evidence — records, observations and interviews — not assumptions. Auditors should not audit their own work.
3. Communication skills
- Asking open questions and listening actively
- Explaining findings clearly and respectfully
- Writing concise, factual nonconformity statements
4. Adding value
The best audits highlight good practice and opportunities for improvement, not only nonconformities.
5. Continual development
ISO 19011 describes the knowledge and skills auditors need. Regular training and practice keep those skills sharp.
