The greatest benefit of using IT risk scenarios is that they facilitate communication of risk, as they provide a clear and realistic description of the risk sources, events, impacts, and responses, and enable the stakeholders to understand and appreciate the risk exposure and appetite of the organization. Supporting compliance with regulations, providing evidence of risk assessment, and enabling the use of key risk indicators (KRIs) are also benefits of using IT risk scenarios, but they are not the greatest benefit, as they are more related to the outcomes or consequences of risk communication, rather than the process or value of risk communication. References = CRISC Review Manual, 7th Edition, page 100.
