The chief audit executive (CAE) can best illustrate the value of the internal audit activity by reporting the overall performance resulting from the internal audit balanced scorecard. The balanced scorecard includes metrics that measure the effectiveness, efficiency, and impact of the internal audit function, providing a comprehensive view of its contributions to the organization. This approach demonstrates how internal audit activities align with and support the organization's strategic objectives. Reference:
