Documenting the results of the risk monitoring and controlling process is important for creating lessons learned. This helps future projects by providing a reference for risk management practices and experiences.

The documentation of the results of monitoring and controlling risks is a valuable source of information for lessons learned. Lessons learned are the documented information that reflects both the positive and negative experiences of a project. They represent the organization's commitment to project management excellence and the project manager's opportunity to learn from the actual experiences of others. By documenting the results of monitoring and controlling risks, the project team can capture the effectiveness of the risk responses, the changes in the risk exposure, the root causes of the risks, the best practices and the lessons learned for future projects.This documentation can help to improve the risk management process, enhance the project performance, and increase the organizational knowledge base.Reference: PMI Risk Management Professional (PMI-RMP) Examination Content Outline and Specifications1, page 10; A Guide to the Project Management Body of Knowledge (PMBOK Guide) -- Sixth Edition, page 406;Lessons learned - PMI.
