The most helpful factor to align when defining thresholds for control key performance indicators (KPIs) is the control performance with the risk tolerance of business owners. Control KPIs are metrics that measurethe effectiveness and efficiency of the controls that are implemented to mitigate the risks. By aligning the control performance with the risk tolerance of business owners, the thresholds for control KPIs can reflect the acceptable level of risk and the desired level of control for the business processes and objectives. Information risk assessments with enterprise risk assessments, key risk indicators (KRIs) with risk appetite of the business, and control KPIs with audit findings are other possible factors to align, but they are not as helpful as control performance with risk tolerance of business owners.
