IPP&E Overview > Understanding the IPP&E business process
Defining the program work breakdown structure
In the program work breakdown structure (WBS) definition process, you define the work necessary to accomplish the program goals, based on the specification of the product, the statement of work, and any terms and conditions imposed by the program. The WBS is organized in a hierarchical manner with the lowest level node representing a task for specific deliverables. This lowest level node of the WBS is called a work package. For each work package identified in the program WBS, you also define the functional work packages for the functional organizations necessary to accomplish the work. IPP&E provides business objects and capabilities for the program WBS definition phase of the program management process.
