The primary reason for an IS audit manager to review the work performed by a senior IS auditor prior to presentation of a report is to ensure the conclusions are adequately supported. The IS audit manager is responsible for overseeing and supervising the audit process, ensuring the quality and consistency of the audit work, and approving the audit report and recommendations. The IS audit manager should review the work performed by the senior IS auditor to verify that the audit objectives, scope, and criteria have been met, that the audit evidence is sufficient, reliable, and relevant, and that the audit conclusions are logical, objective, and based on the audit evidence. The IS audit manager should also ensure that the audit report is clear, concise, accurate, and complete, and that it communicates the audit findings, conclusions, and recommendations effectively to the intended audience. The other options are not the primary reason for an IS audit manager to reviewthe work performed by a seniorIS auditor prior to presentation of a report, because they either relate to specific aspects or stages of the audit work rather than the overall outcome, or they are part of the senior IS auditor's responsibility rather thanthe IS audit manager's.
