Communicating the new risk profile is the best recommendation for a risk practitioner for an organization that recently changed its organizational structure, because it helps to inform and align the stakeholders on the current state of risks and their implications for the organization's objectives and strategy. A risk profile is a summary of the key risks that an organization faces, along with their likelihood, impact, and response strategies. An organizational structure is the way that an organization arranges its people, roles, and responsibilities to achieve its goals and deliver its value proposition. A change in the organizational structure may affect the risk profile, as it may introduce new sources or types of risk, or alter the existing risk levels or responses. Therefore, communicating the new risk profile is the best recommendation, as it helps to ensure that the stakeholders are aware of and prepared for the changes and challenges that the new organizational structure may bring. Implementing a new risk assessment process, revalidating the corporate risk appetite, and reviewing and adjusting key risk indicators (KRIs) are all important tasks to perform after communicating the new risk profile, but they are not the best recommendation, as they depend on the communication and understanding of the new risk profile.
