Risk responses are the actions or strategies that are taken to address the risks that may affect the organization’s objectives, performance, or value creation12.

The most effective way to increase the likelihood that risk responses will be implemented is to assign ownership, which is the process of identifying and appointing the individuals or groups who are responsible and accountable for the execution and monitoring of the risk responses34.

Assigning ownership is the most effective way because it ensures the clarity and commitment of the roles and responsibilities for the risk responses, and avoids the confusion or ambiguity that may arise from the lack of ownership34.

Assigning ownership is also the most effective way because it enhances the communication and collaboration among the stakeholders involved in the risk responses, and provides the feedback and input that are necessary for the improvement and optimization of the risk responses34.

The other options are not the most effective way, but rather possible steps or tools that may support or complement the assignment of ownership. For example:

Creating an action plan is a step that involves defining and documenting the specific tasks, resources, timelines, and deliverables for the risk responses34. However, this step is not the most effective way because it does not guarantee the implementation of the risk responses, especially if there is no clear or agreed ownership for the action plan34.

Reviewing progress reports is a tool that involves collecting and analyzing the information and data on the status and performance of the risk responses, and identifying the issues or gaps that need to be addressed34. However, this tool is not the most effective way because it does not ensure the implementation of the risk responses, especially if there is no ownership for the progress reports or the corrective actions34.

Performing regular audits is a tool that involves conducting an independent and objective assessment of the adequacy and effectiveness of the risk responses, and providing the findings and recommendations for improvement56. However, this tool is not the most effective way because it does not ensure the implementation of the risk responses,especially if there is no ownership for the audit results or the follow-up actions56. References =
