The most helpful activity for a risk practitioner when ensuring that mitigated risk remains within acceptable limits is to implement a process for ongoing monitoring of control effectiveness. This would enable the risk practitioner to track the performance of the controls, identify any deviations or gaps, and take corrective actions as needed. Ongoing monitoring of control effectiveness would also provide assurance that the risk responses are working as intended, and that the residual risk is aligned with the risk appetite and tolerance of the enterprise.
