The most significant benefit of using a consistent risk ranking methodology across an organization is that it enables a clear understanding of risk levels, as this facilitates the comparison and prioritization of risks, the communication and reporting of risks, and the alignment of risk management with the enterprise’s objectives and strategy. A consistent risk ranking methodology is a set of criteria and scales that are used to measure and rate the likelihood and impact of risks, as well as other factors such as urgency, velocity, and persistence. A consistent risk ranking methodology ensures that the risk assessment results are objective, reliable, and comparable across different business units, processes, and projects. The other options are not the most significant benefits of using a consistent risk ranking methodology,although they may be secondary benefits or outcomes of doing so. References = Risk and Information Systems Control Study Manual, Chapter 3: IT Risk Assessment, page 97.
