The most effective way to help ensure accountability for managing risk is to assign process owners to key risk areas. Process owners are the persons or entities that have the authority andresponsibility to manage a specific process or a group of related processes. Process owners help to identify, assess, and respond to the risks associated with the process, and to monitor and report on the process performance and improvement. Process owners also help to communicate and coordinate the process management activities with the relevant stakeholders, such as the board, management, business units, and IT functions. Assigning process owners to key risk areas helps to ensure accountability for managing risk, because it helps to define and clarify the roles and responsibilities of the process owners, and to establish and enforce the expectations and standards for the process owners. Assigning process owners to key risk areas also helps to measure and evaluate the effectiveness and efficiency of the process owners, and to identify and address any issues or gaps in the process management activities. The other options are not as effective as assigning process owners to key risk areas, although they may be related to the risk management process. Obtaining independent risk assessments, assigning incident response action plan responsibilities, and creating accurate process narratives are all activities that can help to support or improve the risk management process, but they do not necessarily ensure accountability for managing risk.
