The primary reason to perform internal QA for an internal audit function is to ensure that the internal audit activity adheres to the Definition of Internal Auditing and the International Standards for the Professional Practice of Internal Auditing (Standards) issued by the Institute of Internal Auditors (IIA), as well as the internal audit methodology and policies of the organization. A QA program enables an evaluation of the internal audit activity's performance, efficiency, effectiveness, and value, and identifies opportunities for improvement. A QA program also helps to enhance the credibility and reputation of the internal audit function among the stakeholders.

The IS auditor should notify audit management of the finding first, as this is a significant issue that may affect the audit scope and objectives. The IS auditor should not notify law enforcement or require the third party to notify customers without consulting audit management first. The audit report with a significant finding should be issued after the audit is completed and the findings are validated. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 247
