What is a Lessons Learned Register and when should it be used?

• A. A repository of experiences and recommendations collected throughout the project to improve future performance; it should be reviewed at closeout and archived for organizational learning.
• B. A list of all project risks and issue logs.
• C. The budget forecast for the next project phase.
• D. The project schedule baseline.

Answer: (A)

A Lessons Learned Register is a living repository of experiences and recommendations collected throughout the project to improve future performance. It captures what worked well and what didn’t, with concrete suggestions so future teams can reuse successful approaches and avoid repeating mistakes. The register is typically reviewed at closeout and archived for organizational learning, ensuring that insights are preserved and accessible for future projects. This knowledge base supports continuous improvement, better planning, and more informed decision-making across the organization. It’s different from a risk and issue log (which tracks current problems), a budget forecast (projected costs), or the schedule baseline (timing plan); those artifacts serve distinct purposes, while the lessons register specifically codifies experiential knowledge for future use.
