Who should audit who within a company?

In a company, internal auditors should audit various departments to ensure compliance with policies, procedures, and regulations while assessing operational efficiency and risk management. External auditors typically review the financial statements and internal controls of the company to provide an independent assessment for stakeholders. Additionally, management should periodically review the performance of internal audit functions to ensure they align with organizational goals and objectives. This multi-layered approach helps maintain accountability and transparency throughout the organization.
