Project Artifact: Lessons Learned Register
Document Reference: PMO-05.07
This document provides a comprehensive, professional reference to understand the purpose and effective usage of the Lessons Learned Register in alignment with the Tasleemat framework.
1. What?
A centralized repository capturing successes, mistakes, and improvement insights across all project phases.
2. Why?
Prevents repeating costly errors, institutionalizes best practices, and improves organizational capability.
3. When?
Initiated early and updated continuously at milestones, phase gates, and project retrospectives.
4. Who?
Maintained by the Project Manager with active contributions from all project team members and stakeholders.
Tailoring Tips
- Conduct structured retrospective discussions at the end of each iteration or milestone.
- Transfer high-impact lessons to the central PMO knowledge repository at project closing.
