CAPM Practice: Determine how to document project controls of predictive, plan-based projects

The lessons learned register captures knowledge gained throughout the project — what worked, what didn't, and recommendations for future projects. At project close, it is finalized and transferred to the organization's process assets, making this knowledge available to future project teams. It is one of the most important organizational learning tools in project management.

**Why not A:** The project charter is created during project initiation to authorize the project. It is not updated at project close to capture lessons learned — it serves a different purpose entirely and is not a repository for project knowledge.

**Why not C:** The issue log tracks current problems and their resolution during the project but is not designed to capture lessons and recommendations for future projects. Issues are operational concerns, not knowledge transfer documents.

**Why not D:** The change log records submitted change requests and their disposition throughout the project. While it provides a historical record, it does not capture the broader lessons about what worked, what did not, and what should be done differently in future projects.
