According to IIA guidance, the CAE has the ultimate responsibility for the internal audit activity but may delegate tasks such as reviewing, approving, and signing engagement reports to qualified internal audit staff.
This delegation helps in managing workload and leveraging expertise within the team. However, the CAE should still periodically review the reports to maintain oversight and ensure quality.

Before developing the audit work program, it is essential to review the contract for evidence of authorization.
This step ensures that the contract is valid and approved by the appropriate parties, forming a critical basis for the compliance audit. By confirming authorization, the auditor can ascertain that the contract is legitimate and enforceable, and understand its key terms and conditions, which is necessary for planning and executing the audit effectively. Other steps, such as selecting a sample or assessing risks, are important but should follow after understanding the contract's validity and scope.

If a significant error or omission is found in the final audit report, it is crucial for the internal audit activity to correct the information and redistribute the corrected report to all original recipients. This ensures that all stakeholders are informed of the accurate findings and can take appropriate actions based on correct information.
IIA References:
* IIA Standard 2440: Disseminating Results requires that the internal audit activity communicate accurate and complete results. If an error or omission is identified, the corrected information must be promptly communicated to all relevant parties to maintain the integrity of the audit process.
* The Practice Guide on Communicating Results emphasizes that errors in audit reports should be corrected and the revised report should be distributed to ensure stakeholders are acting on accurate information.

When the chief audit executive (CAE) is uncertain whether the internal audit team has the necessary knowledge to conduct a specific engagement, such as reviewing testing procedures for a large information system, the most appropriate course of action is to engage an external service provider with the required expertise. This option helps to preserve the independence and objectivity of the internal audit activity.
* IIA Standard 1210 - Proficiency:
* This standard requires that internal auditors possess the knowledge, skills, and other competencies needed to perform their responsibilities. If the current team lacks the necessary skills, the CAE must seek external expertise.
* Preserving Independence:
* Engaging an external service provider helps maintain the independence of the internal audit function, as the expertise is sourced from an independent party. This prevents potential conflicts of interest that might arise if resources are borrowed from within the organization (e.g., from the IT department).
* IIA Practice Advisory 1210.A1-1:
* This advisory suggests that the CAE may employ external experts to provide specialized knowledge for certain audit engagements, ensuring the audit activity remains independent and objective.
* Option A (Contract with the software vendor): This could compromise independence, as the vendor may have a vested interest in the outcome of the audit.
* Option B (Ask for a knowledgeable resource from IT): Using internal resources, especially from the IT department being audited, could impair independence and objectivity.
* Option D (Request resources through the external auditor): This might be appropriate in some cases, but it is not as direct and effective as hiring an external provider with specialized skills for this specific engagement.
Detailed Explanation:Why Not Other Options?Conclusion: Option C is correct as it ensures the internal audit function maintains its independence while acquiring the necessary expertise to conduct the engagement effectively, in line with IIA standards.
