Understanding lessons learned

One of the key values of IPP&E is the availability of the common WBS, containing historical WBS data based on best practices and lessons learned from the past projects. After successful completion of a project, you incorporate the knowledge gained during the planning and execution into the common WBS for use by the new projects.

IPP&E allows you to compare the program WBS and all its related artifacts with similarly configured WBS data in the common WBS. Any difference found between the two is highlighted for subsequent action. You then update the common WBS with any new information from the program WBS, including any new WBS elements or changes to an existing WBS.
