For a one-person audit function, the primary focus is on ensuring that there is a clear understanding of the audit policies and procedures without the need for extensive documentation. According to the IIA's guidance, a memorandum stating the policies and procedures would suffice for a one-person audit function, providing a concise yet comprehensive outline of the necessary protocols to follow. This approach ensures that the sole auditor has clear directives while avoiding the administrative burden of maintaining a more extensive manual that might be necessary for larger audit teams.

In addition to gathering information, a primary objective of a client interview during the planning stage of an audit engagement is to establish rapport with the client. Building rapport helps in fostering a cooperative relationship, ensuring that the client is open and forthcoming with information, which can significantly enhance the effectiveness of the audit.
IIA References:
* IIA Standard 2201: Planning Considerations suggests that internal auditors should establish good communication and rapport with clients during the planning phase to facilitate the audit process.
* The Practice Guide on Effective Interviewing Techniques emphasizes that establishing rapport during initial meetings is crucial for gaining the client's trust and cooperation throughout the audit.

The most likely reason the Chief Audit Executive (CAE) decided to prepare an audit memorandum for management of the logistics department is to allow management to address the identified weakness timely. An audit memorandum serves as a formal communication that highlights the issue and provides management with the necessary details to understand and address the control weakness promptly. This approach facilitates immediate corrective action, thereby reducing the risk associated with the identified weakness.

The primary reason for interviewing operational management during engagement planning is to understand the objectives of the area or process under review. This ensures that the audit aligns with business goals and assesses the relevance of internal controls.
* Validating the engagement work program (A) occurs later in the planning process.
* Assessing management's knowledge of risks and controls (C) is important but not the primary purpose of interviews.
* Reviewing past action plans (D) is relevant for follow-up audits, not initial engagement planning.

When dealing with the communication of audit results to external parties, the internal auditor must adhere to IIA standards regarding confidentiality, approval processes, and the appropriate handling of sensitive information.
* IIA Standard 2440 - Disseminating Results:
* This standard outlines that the chief audit executive (CAE) must approve the communication of engagement results to parties outside the organization. The CAE is responsible for ensuring that the distribution of audit findings is appropriate and does not compromise confidentiality or integrity.
* Confidentiality and Authorization:
* The internal auditor must protect the confidentiality of the information obtained during the audit.
Sharing this information with external parties, such as an advertising agency, should only occur with proper authorization, typically from the CAE.
* IIA Code of Ethics - Confidentiality:
* The Code of Ethics requires auditors to respect the value and ownership of information they receive and to not disclose information without appropriate authority. In this case, if the audit client requests the report to be shared with an external party, the internal auditor must first obtain approval from the CAE to ensure this disclosure is appropriate.
* Option B (May not communicate results): While confidentiality is crucial, the CAE can authorize the sharing of information with external parties if it is deemed appropriate.
* Option C (Include instructions for limited distribution): While limiting further distribution is a good practice, the initial sharing still requires the CAE's approval.
* Option D (Verbal communication only): This restricts the auditor unnecessarily. The key is obtaining proper authorization, not limiting the form of communication.
Detailed Explanation:Why Not Other Options?Conclusion: Option A is correct as it ensures that the results can be communicated to the external party with the appropriate approval from the CAE, in line with IIA standards on dissemination and confidentiality.
