The best time should be a time that will allow for reflection, feedback, and adjustment of any project assumption or other parameters that would contribute to the success of a project. It should be a time that will allow win–win solutions to be identified from issues with different viewpoints, as opposed to the compromise solutions that often occur in projects when a full look back and analysis has not been conducted. In the past, project Lessons Learned were often modeled after the After Action Reviews from the military, in which a review session would be conducted after a military operation to capture Lessons Learned and positively impact the behavior of the team in future exercises. This was a convenient time for such reviews. Documenting Lessons Learned at multiple points during a project allows a look back at the assumptions versus reality of the project and affords the opportunity to define new assumptions for the remaining portions of the project.
