Before writing the internal audit charter, the chief audit executive (CAE) must consider how the internal audit activity is viewed by the board. The internal audit charter is a formal document that defines the purpose, authority, and responsibility of the internal audit activity. It should align with the expectations and requirements of the board and senior management. Understanding the board's perception and expectations helps in crafting a charter that ensures appropriate support and engagement from key stakeholders, thereby enhancing the effectiveness and alignment of the internal audit function with organizational objectives.
