According to the CRISC Review Manual1, a risk action plan is a document that defines the specific actions, resources, responsibilities, and timelines for implementing the risk responses. A risk action plan should be developed after the results of a vulnerability assessment are shared with the relevant stakeholders, such as the business manager, to address the identified vulnerabilities and mitigate the associated risks. Developing a risk action plan is the next step in the risk management process, as it helps to ensure that the risk responses are executed effectively and efficiently, and that the residual risks are within the acceptable levels.
