Lessons Learned
Lessons Learned are a retrospective look at a project, or phase of a project, to identify best practices to be repeated and performance gaps to be improved.
When to use
Lessons Learned should be conducted soon after the project has completed. For long complex projects, consider doing a Lessons Learned session after each phase. This is because team members often change during long projects and it is difficult to remember what was good or bad in the project for events that happened years ago.
Instructions
- Lessons Learned: “The knowledge gained during a project which shows how project events were addressed or should be addressed in the future with the purpose of improving future performance.” PMBOK® Guide
- A Lessons Learned session should include all of the relevant team members.
- It is often helpful to have a facilitator run the meaning. This minimizes personality confrontations.
- The purpose is to identify best practices and improvement gaps – not assign blame.
- Results should be maintained in a project database or knowledge management system for reference by future project teams
- Questions should be directed in these four areas.
Project initiation
- Did we choose a good project?
- Were goals and objectives clear?
- Were boundaries clear?
Project planning
- Was our plan complete?
- Were estimates accurate?
- Were risks identified and managed?
Project execution
- Did we follow the plan?
- Did we recognize issues & implement changes when needed?
- Team strengths and weaknesses?
Project management methodology
- Did the methodology help or hurt?
- Were stakeholder interactions timely & at the right depth?
