An engagement work program is of greatest value to audit management when it helps ensure the achievement of the engagement objectives. The work program outlines the audit procedures and tests that need to be performed to gather sufficient and appropriate evidence to support the audit findings and conclusions. By aligning the work program with the engagement objectives, auditors can focus their efforts on the most critical areas, ensure that all necessary steps are taken, and ultimately achieve the intended outcomes of the audit.
