AI as a tool for the Internal Auditor

AI is not only an important object to audit. It is also a valuable tool for the internal auditor himself. By cleverly deploying Artificial Intelligence for auditors, the audit function can work faster, more effectively and in a more risk-oriented way. This creates more assurance for the board and management and Internal Audit can strengthen its role as a third line.

The opportunities of AI in Internal Audit

AI provides support at all stages of the audit cycle:

• In planning, AI helps analyze internal and external data to better prioritize risks.
• During execution, AI supports data analysis, process mining and document review, among other things, allowing auditors to achieve greater depth and broader coverage.
• In reporting, AI can generate draft texts and turn complex information into clear visuals, among other things.
• In follow-up, AI enables real-time monitoring of measures and key risk indicators.
• In evaluation and quality assurance, AI can analyze audit files, identify trends and contribute to the Quality Assurance & Improvement Program (QAIP).

In short, AI can add value at every stage of the audit cycle, if applied carefully and responsibly.

Structural application of AI in audit

For internal auditors, AI must always be applied with integrity and transparency. Outcomes must be explainable and should never replace professional judgment. The challenge is to move beyond experimentation and make AI truly part of audit practice.

This requires a structured approach. A prompt library of proven applications helps with this. Equally important is sharing successes, both within the audit team and with other functions in the organization. In this way, knowledge is not fragmented, but secured.

Also crucial is a culture of learning and improvement. Only when experiments grow into established practices can AI be sustainably integrated into Internal Audit and contribute to further strengthening the field.
