What is internal audit?

At its core, internal audit is about helping organisations achieve their objectives by providing independent assurance and practical advice.

AI will not replace internal auditors. It will help them analyse more information and identify risks more efficiently. Organisations will still need people who can exercise judgement, understand context, communicate with stakeholders and provide independent assurance.

Tomorrow's internal auditors will combine technology capability with critical thinking, professional judgement and strong communication.
