Conformance with the Standards during an external assessment of the internal audit activity can be demonstrated through various means. One critical aspect is the review process of audit workpapers. According to the IIA Standards, particularly Standard 2340 - Engagement Supervision, audit work should be reviewed by an engagement supervisor to ensure objectives are achieved, quality is maintained, and staff are developed.
The review and sign-off of all audit workpapers before the issuance of the audit report (Option C) align directly with these standards, ensuring that work meets the required quality and thoroughness.References:
