Implementing the lessons learned from the program

When a program execution is complete, you can use the WBS artifacts created for that program to enrich the common WBS. You compare the program WBS with the common WBS with the View → Compare command to identify updates and actions. All artifacts in both the program WBS and the common WBS are under configuration control to manage variability, allowing for a valid comparison. This is a closed-loop process to support continuous improvement.

Comparisons can also be made at any time prior to program completion to capture critical improvements.
