Enhancing stakeholders' perception of the value added by the internal audit activity (IAA) involves demonstrating strong relationships with audit clients (Option 3) and participating in project teams and task forces in an advisory capacity (Option 4). These activities show the IAA's active involvement in the organization's operations and its commitment to adding value beyond traditional auditing roles. While the use of computer-assisted audit techniques (Option 1) and a consistent risk-based approach (Option 2) are important, they are more related to internal audit efficiency and effectiveness rather than directly enhancing stakeholder perception of value.

When the internal audit activity lacks the necessary IT expertise to review the information security function, the chief audit executive (CAE) should contract an external service provider with the required experience.
This ensures that the audit is conducted effectively and in accordance with the Standards, which require internal auditors to have or acquire the necessary skills to perform their work.

* IIA Standard 1210: Proficiency requires internal auditors to possess the knowledge, skills, and other competencies needed to perform their responsibilities. When the necessary expertise is not available within the internal audit activity, the CAE must obtain competent advice and assistance by either contracting external experts or outsourcing the audit.
* The Practice Guide on Engaging External Service Providers suggests that when specialized skills are required, engaging an external service provider is a practical solution to ensure the audit's quality and effectiveness.

* Identify the Conflict of Interest: The internal auditor learns about a large loan made to another auditor's relative, which represents a conflict of interest.
* Refer to Professional Standards: According to the Institute of Internal Auditors' (IIA) standards, an internal auditor must maintain objectivity and avoid conflicts of interest (IIA Standard 1100 - Independence and Objectivity).
* Escalate the Issue: The appropriate course of action is to escalate this matter to the chief audit executive (CAE) and management, as they are responsible for determining the impact of the conflict and the appropriate response.
* Decision Making: The CAE and management will assess whether the conflict of interest could impair the auditor's objectivity and decide whether the auditor should be removed from the engagement or if additional oversight is needed.
* Documentation: It is important to document the conflict and the decision-making process in the audit documentation for transparency and accountability.

The primary objective of an internal audit engagement supervisor is to uphold the quality of the internal audit actively. This involves ensuring that the audit procedures are performed effectively, the findings are accurate and reliable, and the audit meets the necessary professional standards. The supervisor oversees the audit team's work, provides guidance and support, and ensures that the engagement is conducted according to the internal audit plan and methodology. This role is crucial in maintaining the credibility and integrity of the audit function.

Internal auditors can rely on the work of other assurance providers, including internal compliance teams, to expand their audit coverage efficiently. This practice is based on the principle of leveraging existing assurance functions within the organization to avoid duplication of efforts and to use resources more effectively. By relying on the work performed by compliance teams, internal auditors can ensure comprehensive coverage without necessarily increasing the direct audit hours. However, it is crucial that the internal auditors evaluate the competence and objectivity of the compliance teams and ensure that their work meets the required standards before relying on it.
