Lessons Learned in PM – Definition and Meaning
Lessons Learned refer to the structured process of recording, documenting, and sharing experiences, insights, and best practices from completed projects or project phases. They serve to systematically identify and analyze both positive and negative experiences and make them available for use in future projects. Lessons learned are typically collected in workshops, retrospectives, or reviews and recorded in knowledge databases or lessons learned documents to promote continuous improvement.
Example, best practice, and further information on the term
After completing a software development project, the team could, for example, determine in a lessons learned workshop that unclear requirements led to delays and that a structured requirements review process would help in the future. A best practice is to systematically collect and document lessons learned and actively incorporate them into the planning of new projects. This is in line with knowledge management and continuous improvement processes according to PMBOK and agile principles of retrospectives. Effective lessons learned promote organizational learning and help to avoid repeating mistakes and replicate successes.
