The primary purpose of using a framework for risk analysis is to improve consistency. A framework for risk analysis is a set of principles, standards, methods, and tools that guide and govern the risk analysis process. Risk analysis is the process of estimating the impact and likelihood of the risk events, and determining the level and nature of the risk exposure. A framework for risk analysis helps to improve consistency, which is the degree of uniformity and agreement among the risk analysis results and practices. Improving consistency helps to ensure that the risk analysis is performed in a systematic and structured way, and that the risk analysis results are comparable and reliable. Improving consistency also helps to reduce the bias, uncertainty, and variability in the risk analysis process, and to enhance the quality and accuracy of the risk analysis results. Improving accountability, helping define risk tolerance, and helping develop risk scenarios are not the primary purposes of using a framework for risk analysis, asthey are either the benefits or the objectives of the risk analysis process, and they do not addressthe primary need of improving the quality and reliability of the risk analysis results. References = CRISC Review Manual, 6th Edition, ISACA, 2015, page 49.
