What should be the PRIMARY driver for periodically reviewing and adjusting key risk indicators (KRIs)?

Risk appetite should be the primary driver for periodically reviewing and adjusting key risk indicators (KRIs), because it reflects the level of risk that the enterprise is willing to accept in pursuit of its objectives. KRIs should be aligned with the risk appetite and adjusted accordingly when the risk appetite changes due to internal or external factors. The other options are not the primary drivers, although they may also influence the review and adjustment of KRIs. Risk impact, risk likelihood, and control self-assessments (CSAs) are secondary drivers that depend on the risk appetite. References = Most Asked CRISC Exam Questions and Answers
