 The primary reason for establishing various threshold levels for a set of key risk indicators (KRIs) is to take appropriate actions in a timely manner. KRIs are metrics that provide information on the level of exposure to a given risk or the effectiveness of the controls in place. Threshold levels are predefined values that indicate when the risk level is acceptable, tolerable, or unacceptable. By establishing various threshold levels for a set of KRIs, the enterprise can monitor the risk situation and trigger the necessary responses before the risk becomes too severe or costly to mitigate. The other options are not the primary reasons for establishing various threshold levels, although they may be secondary benefits or outcomes of doing so. References = Risk and Information Systems Control Study Manual, Chapter 5: Risk and Control Monitoring and Reporting, page 189.
