Which is a purpose of a Lessons Log?

The purpose of the Lessons Log is to be a formal repository for capturing and documenting lessons that can be applied to the current project and to future projects. These lessons can be identified at any point. Checkpoint Reports, which detail the progress of a Work Package, are a common source for identifying issues, risks, and lessons that should be formally logged in the Lessons Log for review and action.

B. The Lessons Log records the lesson itself; corrective actions are typically managed via the Issue Register or Risk Register.
C. Lessons are formally escalated to the Project Board using a Lessons Report, not directly from the Lessons Log.
D. While lessons may lead to improvements in assurance, the log's primary purpose is to capture lessons, not to directly raise issues with Project Assurance.
