Being able to document lessons learned after a project is complete (or even in the middle of it) is one of the biggest responsibilities a project manager has on a project. If one does not understand the mistakes of past projects, then one is doomed to repeat them over and over. In this role, the project manager becomes part historian and part archivist. Lessons learned are not just useful in the business world; they can be helpful on any project in which one is involved - at home or in your volunteer work or in your own personal hobbies. Lessons learned can make all the difference on future projects and help them to succeed, but first, they must be documented correctly.
