WORK BREAKDOWN STRUCTURES FOR DEFENSE MATERIEL ITEMS
|Publication Date:||6 October 2020|
Standard Purpose and Structure.
This Standard presents direction for effectively preparing, understanding, and presenting a Work Breakdown Structure (WBS). It provides the framework for Department of Defense (DoD) Program Managers to define their program's WBS and to defense contractors in their application and extension of the Program and contract's WBS to report additional details associated with their agreements with Government Program Managers. Section 1 defines and describes the WBS. Section 2 provides instructions on how the WBS is applied as well as how to develop a Program WBS in the pre-award timeframe (i.e., before a contract or government performed effort has begun). Section 3 provides direction for developing and implementing a Contract WBS and Section 4 examines the role of the WBS in the post-award timeframe. Throughout this standard, the word "contract" and "defense contractor" is used to refer to both literal contracts with private industry but also refers to agreements between a Program Office and other government organizations (e.g., test sites, depots, labs, federally funded research and development centers (FFRDC)). This Standard also provides WBS definitions for specific defense materiel commodity systems in Appendices A through J. Appendix K addresses WBS elements that are common to all systems, as well as those which use unique elements (e.g., Space Systems, Information Systems/Defense Business Systems, Launch Systems, and Strategic Missile Systems). Appendix L presents for the Cost Assessment and Program Evaluation (CAPE) Sustainment Cost Estimating Structure (CES) and its associated definitions for informational purposes. The purpose of providing sustainment information is to present an explanation of transitioning from reporting using a WBS to reporting sustainment costs using the CES, regardless of acquisition phase or type of funds used.
The primary objective of this Standard is to achieve a consistent application of the WBS for all programmatic needs (including performance, cost, schedule, risk, budget, and contractual). Discussion and direction was compiled based on many years of lessons learned in employing WBSs on defense programs.

This Standard is directed primarily at preparing a WBS for a defense system program. This includes all systems, materiel items, or major modifications established as an integral program element of the Future Years Defense Program or otherwise designated by the DoD component or the Under Secretary of Defense (AT&L).
The Standard is appropriate for use with any WBS developed for the Pre-Systems Acquisition (Materiel Solution Analysis, Technology Maturation/Risk Reduction) and Systems Acquisition (Engineering and Manufacturing Development, Production and Deployment) life cycle phases. The Sustainment Phase (Operations and Support) is addressed as it is included during the Systems Acquisition Phase until the Material Support Date (MSD) early in Operations and Support. The Standard focuses on identifying how a WBS is developed and maintained throughout the Pre-Systems Acquisition and Systems Acquisition phases including its transition to Sustainment.
This Standard clearly delineates the overlapping responsibilities of DoD program managers and contractors relative to the execution of WBSs.View Less
