An internal audit function has commenced its annual follow-up activity.

When performing follow-up work, the first step for an auditor—especially one not previously involved in the engagement—is to review the prior audit report, findings, and management’s agreed response/action plan. This provides context on what needs to be validated before collecting new evidence.

Interviewing management (Option A), requesting documentation (Option B), or performing walkthroughs (Option D) are important steps, but they come only after the auditor has reviewed the original findings and corrective commitments.
