A risk manager notices that a risk owner is facing challenges implementing their response strategy...

The first thing the risk manager should do is analyze the situation and meet with the risk owner. This will allow the risk manager to understand the challenges faced by the risk owner and work with them to find a solution. Conducting a cost-benefit analysis or changing the risk response strategy may be necessary, but it is important to first understand the situation before taking any action.

According to the PMI-RMP Exam Content Outline, one of the tasks in the domain of Risk Response Planning is to “assist the risk owners in developing and implementing risk response strategies and actions based on the agreed-upon risk response plan”. Therefore, the first thing the risk manager should do is to analyze the situation and meet with the risk owner to understand the root cause of the challenges and the cost overrun, and to discuss possible solutions or alternatives. Highlighting this situation to the project manager, conducting a cost-benefit analysis, or changing the risk response strategy are possible actions that can be taken after the analysis and meeting, but not before. References: PMI-RMP Exam Content Outline, Domain 3: Risk Response Planning, Task 31
