Work Breakdown Structure (WBS)
Work Breakdown Structure A Product-Oriented Family Tree that Establishes the Framework for Correlating Program Planning, Scheduling, Cost Estimating, Budgeting, Contracting, Configuration Management, and Performance Reporting
Work Breakdown Structure Developed Early in the Conceptual Phases of the Program but no Later than the Proposal Phase Kept Current, Evolving with Changes in the Program Driven by Risk - the Higher the Risk, the Lower the Level Developed for any program regardless of size and complexity Links SOW, Schedule, and PMB for program management
Special Considerations Each hardware Element Includes all Effort Associated with; Hardware Design Software Procurement Manufacturing Unit Test Use Specific Terminology, Not Generic Terms Meaningful Product or Management Oriented Indentures Not Required to Go to Same Level in all Areas Recurring and Non-Recurring are Types of Cost Not WBS Levels Cost Accumulation/Cost Requirements Establish Cost History Customer Requirements; Levels, Breakouts, etc.
