Explanation: The risk management plan, part of the comprehensive management plan, defines how risks will be identified, analyzed, monitored and controlled, and even responded to. A Risk management plan is a document arranged by a project manager to estimate the effectiveness, predict risks, and build response plans to mitigate them. It also consists of the risk assessment matrix. Risks are built in with any project, and project managers evaluate risks repeatedly and build plans to address them. The risk management plan consists of analysis of possible risks with both high and low impacts, and the mitigation strategies to facilitate the project and avoid being derailed through which the common problems arise.
