Key risk indicators (KRIs) are metrics that provide early warning signals of potential risk events or changes in the risk profile of an organization. They help to monitor the risk exposure and performance of the organization against its risk appetite and tolerance. They also enable timely and proactive risk responses and mitigation actions. Establishing KRIs is the most helpful in preventing risk events from materializing, as they can alert the organization of emerging risks and trigger preventive measures before the risks become significant or materialize. References = Risk and Information Systems Control Study Manual, Chapter 3, Section 3.3.1, p. 114-115
