The best way to ensure adequate resources will be allocated to manage identified risk is to assign risk ownership to appropriate roles. Risk ownership is the process of assigning the authority and responsibility to manage a specific risk or a group of related risks to a person or entity. Risk ownership helps to ensure adequate resources for managing risk, because it helps to define and clarify the roles and responsibilities of the risk owners, and to establish and enforce the expectations and standards for the risk owners. Risk ownership also helps to measure and evaluate the effectiveness and efficiency of the risk owners, and to identify and address any issues or gaps in the risk management activities. The other options are not as effective as assigning risk ownership to appropriate roles, although they may be related to the risk management process. Prioritizing risk within each business unit, reviewing risk ranking methodology, and promoting an organizational culture of risk awareness are all activities that can help to support or improve the risk management process, but they do not necessarily ensure adequate resources for managing risk.
