What is the purpose of a lessons learned register?

• A. Capture knowledge gained from the project to improve future work and avoid repeating mistakes.
• B. Document personnel attendance.
• C. Track quality issues.
• D. Store vendor contracts.

Answer: (A)

The key idea is that a lessons learned register gathers knowledge and insights from the project so future work can benefit. Its purpose is to capture what was learned—good practices, what didn’t work, and concrete recommendations—so teams can improve processes and avoid repeating mistakes on similar projects. By documenting these lessons with owners and action steps, the organization can feed this knowledge back into future initiatives and update its overall process assets. Other records serve different purposes: attendance is tracked in people records, quality issues live in the quality management area, and vendor contracts reside in procurement documentation.
