A risk profile is a summary of the key risks that affect an organization, a business unit, a process, or a project. A risk profile can help stakeholders understand the current and potential exposure to various sources of uncertainty, and prioritize the risk response accordingly. Classification of risk profiles is the process of grouping and categorizing risks based on common characteristics, such as source, impact, likelihood, or response strategy. Classification of risk profiles can help communicate risk assessment results to stakeholders by providing a clear and consistent way of presenting and comparing risks across different domains, levels, or perspectives. Classification of risk profiles can also help identify patterns, trends, and interrelationships among risks, and facilitate the allocation of resources and responsibilities for risk management.
