The internal audit activity is responsible for conducting fraud investigations.

When a potential fraud instance is identified, the chief audit executive (CAE) appoints a lead investigator to manage the investigation. The next critical step is to determine the competencies needed for the investigation and assess whether the team members have any conflicts of interest. This ensures that the investigation team has the appropriate skills, knowledge, and objectivity to handle the case effectively. Ensuring there are no conflicts of interest is vital to maintain the integrity and credibility of the investigation process.
