2.2.1 Developing and Documenting a Program WBS. The program
manager is responsible for maintaining the Program WBS as it develops through
systems engineering and management planning processes. The WBS may span one or
more of the categories or elements defined in Appendices A-H. While these elements
normally provide a basis for the Program or Contract WBS, tailoring may
occur when a unique requirement exists, which these appendices do not
address. In addition, although each appendix relates to a specific category of
defense items, any item from any appendix which is applicable to the program
may be used, as long as the integrity of the level of placement is
The Program WBS should guide development early in the programís life cycle.
It will evolve through iterative analysis of the program objective, functional
design criteria, program scope, technical performance requirements, and other
technical documentation. The documentation should describe the entire
plan to build, field, and support the system throughout its life cycle.
The Cost Analysis Requirements Description (CARD) will be the recording
document for this program plan. Ultimately, the Program WBS is approved
through the Cost and Software Data Reporting (CSDR) plan, which describes the
Program WBS to be used and defines the approach the Government activity plans
to use for collecting cost data.
