One of the critical tasks involves approving the engagement work program. The work program outlines the detailed steps and procedures that the audit team will follow during the engagement. By approving this program, the supervisor ensures that it is comprehensive, aligned with the engagement objectives, and capable of addressing identified risks and controls effectively.
