This HANDBOOK is approved for use by all Departments and Agencies of the Departmentof This HANDBOOK is for guidance only. This HANDBOOK cannot be cited as a it is, the contractor does not have to A work breakdown structure (WBS) provides a consistent and visible framework fordefense materiel items and contracts within a program.

2 This HANDBOOK offers uniformity indefinition and consistency of approach for developing the top three levels of the workbreakdown structure. The benefit of uniformity in the generation of work breakdownstructures and their application to management practices will be realized in improvedcommunication throughout the acquisition This HANDBOOK addresses mandatory procedures for those programs subject to DODR egulation It also provides guidance to industry in extending contract workbreakdown This HANDBOOK is a conversion of MIL-STD-881B, Work Breakdown Structures forDefense Materiel Items.

7 Tatement of WorkWBSWork Breakdown StructureMIL-HDBK-881vi(THIS PAGE LEFT INTENTIONALLY BLANK)MIL-HDBK-8811 CHAPTER 1:GENERAL HANDBOOK PURPOSE AND STRUCTUREThis HANDBOOK presents guidelines for preparing, understanding, and presenting awork breakdown structure (WBS). After the general purpose of work breakdownstructures is discussed in Chapter 1, the HANDBOOK provides instructions on how todevelop a program work breakdown structure (Program WBS) in Chapter 3 offers guidance for developing and implementing a contract workbreakdown structure (Contract WBS).

8 Chapter 4 examines the role of the workbreakdown structure in contract negotiation and award and in post-contractperformance. The appendices present definitions of work breakdown structures forspecific applications. The HANDBOOK s primary objective is to achieve a consistentapplication of the work breakdown structure. The information it contains isintended to provide guidance to contractors and direction to government SUPPORT DOCUMENTATIONThe foundation for work breakdown structures is contained in DoD and DoD Regulation These documents identify responsibilities inthe acquisition process from the Office of the Secretary of DEFENSE to theDepartment of DEFENSE (DoD) component field activities.

9 Preparing a workbreakdown structure is generally discussed in the context of planning andmonitoring a DEFENSE materiel system INTENDED USE OF HANDBOOKThis HANDBOOK is directed primarily at the preparation of a work breakdownstructure for a DEFENSE materiel item. This includes all materiel items or majormodifications established as an integral program element of the Future YearsDefense Program or otherwise designated by the DoD component or the UnderSecretary of DEFENSE (Acquisition and Technology).

10 The guidance is appropriate for use with any work breakdown structure developedat any phase Concept Exploration, Program Definition and Risk Reduction,Engineering and Manufacturing Development, or Production during theacquisition HANDBOOK clearly delineates the overlapping responsibilities of DoD programmanagers and contractors relative to work breakdown WHAT DOES A WORK BREAKDOWN STRUCTUREACCOMPLISH? ApplicationsThis HANDBOOK addresses two fundamental and interrelated types of workbreakdown structures the Program WBS and the Contract WBS.
