An internal audit engagement supervisor approved the engagement work program submitted by an internal auditor...

According to Standard 2340 – Engagement Supervision, engagement work must be properly supervised to ensure that objectives are achieved, quality is maintained, and staff are developed. Supervision is not limited to approving the engagement program at the beginning; it requires ongoing review of workpapers and fieldwork throughout the engagement. This includes providing timely feedback, asking clarifying questions, and ensuring consistency and sufficiency of evidence.

In this case, the supervisor only reviewed the work program at approval and after completion, which is inadequate. The required improvement is regular, ongoing review of workpapers and guidance throughout the engagement. This directly aligns with Standard 2340’s requirement for continuous supervision rather than only final review.
