Lower level elements must come from MIL-STDC where available. • Created by CWIPT prior to RFP. – Data quality increases when WBS defined up front. Derived from MIL-STDC. • Product-oriented WBS structure composed of hardware, software, services, data, and facilities elements. • Created by CWIPT at . 17 Jul A Work Breakdown Structure (WBS) (MIL-STDC) is a tool used to define a project in discrete work elements in a Hierarchical format.

MIL-STDC is based on the cooperative efforts of the military services with assistance from industrial associations. This top-down structure provides a continuity of flow down for all tasks.

Though WBS development is a systems engineering activity, it impacts costing, scheduling and budgeting professionals, as well as contracting officers. An integrated team representing these Stakeholders is needed to support WBS development.

It is a product-oriented family tree composed of hardware, software, services, data, and facilities, which result from systems engineering efforts during the development and production of the system and its components, and which completely defines the program. This Standard offers uniformity in definition and consistency of approach for developing all levels of the WBS.

This Standard addresses mandatory procedures for all programs subject to DoD Instruction Overall System Level 2: It is for direction and mjl be included as a contract requirement. C Download File – 2. In other words the WBS is an organized method to breakdown a product into subproducts at lower levels of detail.


This military standard is applicable to all defense materiel items or major modifications a established as an integral program element of the Future Years Defense Program FYDPor b otherwise designated by the DoD Component or the Under Secretary of Defense Acquisition.

It also provides direction to industry in extending contract work breakdown structures. xtd

The WBS defines the total system of hardware, software, services, data, and facilities, and relates these elements to each other and to the end product. The Tsd with the support of systems engineering develops the first three levels of the program WBS, and to provide contractors with guidance for lower-level WBS development. Generating and applying uniform work sdt structures improves communication in the acquisition process. A program WBS is established to provide the framework for program and technical planning, cost estimating, resource allocation, performance measurement, and status reporting.

Enough levels must be provided to properly define work packages for cost and 881x control purposes. A Work Breakdown Structure WBS provides a consistent and visible framework for defense materiel items and contracts within a program.

It relates the elements of work mmil be accomplished to each other and to the end product. Changes to the Standard specifically address advances in technology and modifications of the acquisition process, and incorporates new materiel items, developmental concepts, and approaches.

Major Elements Segment Level 3: The WBS is a means of organizing system development activities based on system and product decompositions. The WBS is prepared from both the physical and system architectures, and identifies all necessary products and services needed for the system.
