The primary objective when implementing a risk management framework is to enhance an organization's confidence in achieving its strategy. A risk management framework helps an organization identify, assess, and manage risks that could impact its ability to achieve strategic objectives. By systematically managing risks, the organization can make informed decisions, allocate resources more effectively, and improve its overall resilience, thus increasing confidence in achieving its strategic goals.

This step ensures that the CAE is aware of the situation and can decide on the necessary follow-up actions, such as further investigation or adjusting the audit scope to address the risk.
