A Lessons Learned Report is a document that captures valuable information and insights gained from a project or program. The purpose of the report is to identify and document what went well and what did not, in order to improve future performance and decision-making. The report typically includes information on project objectives, strategies, processes, and outcomes, as well as any issues or challenges encountered and the actions taken to address them. The report should be written in a clear and concise manner, and should be distributed to all relevant stakeholders for review and feedback.
