What is the PRIMARY reason to periodically review key performance indicators (KPIs)?

According to the CRISC Review Manual, the primary reason to periodically review key performance indicators (KPIs) is to identify trends, because it helps to monitor the changes and patterns in the performance and effectiveness of the risk management processes and controls. KPIs are metrics that measure the achievement of the objectives and targets of the risk management activities. Periodically reviewing KPIs allows the organization to evaluate the progress and results of the risk management strategies and actions, and to identify any gaps, issues, or opportunities for improvement. The other options are not the primary reason to periodically review KPIs, as they are related to other aspects or outcomes of the risk management process. Ensuring compliance is the reason to review key risk indicators (KRIs), which are metrics that measure the level of risk exposure and the occurrence of risk events.Promoting a risk-aware culture is the reason to review key goal indicators (KGIs), which are metrics that measure the alignment of the risk management with the business goals and values. Optimizing resources needed for controls is the reason to review key control indicators(KCIs), which are metrics that measure the efficiency and adequacy of the risk controls. References = CRISC Review Manual, 7th Edition, Chapter 3, Section 3.3.2, page 143.
