To ensure that recommendations for enhancing internal controls have been effectively implemented, the internal auditor should conduct appropriate testing to verify management responses. This involves re- performing procedures, reviewing documentation, and possibly observing operations to confirm that the corrective actions have been adequately executed and are effective. Simply seeking a management assurance declaration (Option B) or observing corrective measures (Option A) may not provide sufficient evidence of proper implementation. Following up during the next scheduled audit (Option C) may delay the verification process, potentially allowing risks to persist.

To mitigate the risk that all bank accounts may not be included in the daily reconciliation process, the most effective response is to ensure that the treasury analyst reviews a daily report generated by the treasury system. This report highlights any bank statements that have not been uploaded into the accounting system, ensuring that all accounts are accounted for in the reconciliation process. This automated approach reduces the risk of human error and ensures completeness and accuracy in the reconciliation process.

Best practices in internal auditing emphasize the importance of follow-up on engagement outcomes to ensure that agreed-upon actions are implemented and effective. According to Standard 2500 - Monitoring Progress, the chief audit executive must establish and maintain a system to monitor the disposition of results communicated to management. This ensures that corrective actions are taken and that the internal audit function fulfills its role in improving the organization's governance, risk management, and control processes.
Allocating resources for follow-up is crucial to maintain accountability and support continuous improvement.

The primary objective of an internal auditor during an exit conference is to ensure that the engagement conclusions are accurate and that the facts presented in the audit report are correct. This involves discussing the audit findings with the engagement client, clarifying any misunderstandings, and ensuring that the conclusions are based on accurate and complete information.

* IIA Standard 2440: Disseminating Results emphasizes the importance of accurate and clear communication of audit results. The exit conference is a key part of this process, ensuring that any discrepancies or concerns are addressed before finalizing the report.
* The Practice Guide on Conducting Exit Conferences highlights the importance of using the exit conference to verify that the auditor's conclusions are well-founded and that the client understands and agrees with the findings.

The primary guideline for preparing audit engagement workpapers is that they should be understandable to another internal auditor who was not involved in the engagement. This ensures that workpapers are clear, complete, and sufficiently detailed so that another auditor can understand the work performed, the evidence gathered, and the conclusions reached without needing additional explanations.
IIA References:
* IIA Standard 2330: Documenting Information requires internal auditors to document relevant information to support the conclusions and engagement results. The Practice Advisory 2330-1 emphasizes that workpapers should be understandable and provide a clear trail of the audit process and conclusions, facilitating peer review and quality assurance processes.
* The IIA's Practice Guide on Audit Documentation suggests that workpapers should be prepared with the understanding that another internal auditor, unfamiliar with the work, may need to review them for quality assurance or other purposes.
