The PRIMARY benefit associated with key risk indicators (KRls) is that they:

Key risk indicators (KRIs) are metrics that provide information on the level of exposure to a given risk. They enable ongoing monitoring of emerging risk by alerting the organization when the risk level exceeds thepredefined threshold or tolerance. By using KRIs, the organization can track the changes in the risk environment and take timely and appropriate actions to mitigate or avoid the risk.

Helping an organization identify emerging threats, benchmarking the organization’s risk profile, and identifying trends in the organization’s vulnerabilities are all possible uses of KRIs, but they are not the primary benefit. The primary benefit is to enable ongoing monitoring of emerging risk, which encompasses all these aspects and more. References = CRISC Review Manual, 7th Edition, ISACA, 2020, page 27-281
