According to the Institute of Internal Auditors (IIA) guidance, the chief audit executive (CAE) should develop a risk-based audit plan that takes into account the organization's risk management framework, including its risk appetite levels. This aligns with Standard 2010 - Planning, which states that the CAE must establish a risk-based plan to determine the priorities of the internal audit activity, consistent with the organization's goals. Risk appetite levels from management are a critical component of understanding the organization's risk profile and should be incorporated into the audit plan. Thus, the CAE may incorporate risk information, including risk appetite levels from management, at her discretion.
