The most important element of an organization’s risk register to update following the commissioning of a new financial reporting system is the risk rating of affected financial processes. A risk rating is a measure of the level and nature of the risk exposure, based on the impact and likelihood of the risk events. A risk rating can help to prioritize and respond to the risks, and to monitor and report the risk status. A new financial reporting system may introduce new or different risks, or change the existing risks, that could affect the financial processes of the organization, such as data quality, accuracy, timeliness, compliance, or security. Therefore, the risk rating of affected financial processes should be updated to reflect the current risk situation and to ensure that the risk register is accurate and complete. Key risk indicators (KRIs), the owner of the financial reporting process, and the list of relevant financial controls are not asimportant as the risk rating of affected financial processes, as they are not directly affected by the commissioning of a new financial reporting system, and they do not measure the risk exposure and impact of the financial processes. References = CRISC Review Manual, 6th Edition, ISACA, 2015, page 48.
