Policies and standards are important components of the risk management process, as they define the objectives, expectations, and requirements for managing risk within the organization. Policies and standards are also the means by which senior management formally approves and communicates the risk practices to the stakeholders, ensuring that the risk management process is aligned with the organizational strategy, culture, and values. Policies and standards also provide the authority and accountability for the risk management roles and responsibilities, as well as the criteria and metrics for measuring and reporting risk performance.
