Lessons learned are documents used for future reference. They allow other project managers to learn from the current project. 1 is incorrect. The project plan and scope statement keep the project manager focused on the project work, not the lessons learned documentation. 2 is incorrect. Various reports are used to communicate with management, not lessons learned documentation. This is not to say that management won’t review the lesson learned, it’s just not the best answer for the question. Management will expect reports and other communications to keep them informed. 3 is incorrect. Lessons learned do not ensure that the project work is complete. Scope verification, peer reviews, and other mechanisms can ensure that the project work is complete.
