Ongoing monitoring and periodic internal quality assessments best serve to deter unethical behavior and encourage objectivity among internal auditors. These quality assessments ensure that audit activities conform to professional standards and that auditors uphold principles such as objectivity. This approach provides a structured and systematic review of audit processes and practices, which reinforces the importance of adherence to ethical standards and professional conduct.

According to IIA guidance, the scope of a consulting engagement is determined by either the engagement supervisor or the chief audit executive (CAE), and it is finalized before beginning fieldwork. This ensures that the objectives, deliverables, and expectations are clearly defined and agreed upon by all parties involved. This clear definition helps guide the consulting engagement, ensuring that it meets the client's needs and aligns with the internal audit activity's capabilities.

Intentionally leaving out material observations from the audit report clearly indicates a compromise in the independence of the internal audit. Independence is fundamental to the credibility of the audit function, and any actions that suggest altering audit reports to omit significant findings undermine this principle. Such behavior may suggest an effort to avoid conflict or negative reactions from management, directly impacting the objectivity and integrity of the audit results.
