- 'A Work Breakdown Structure (WBS) is a hierarchical structure of things that the project will make or outcomes that it will deliver' This one is far better. Let's simplify things further: 'A work breakdown structure defines all the things a project needs to accomplish, organized into multiple levels, and displayed graphically.'.
- WBS Code: A unique identifier assigned to each element in a Work Breakdown Structure for the purpose of designating the elements hierarchical location within the WBS. Work Package: A Work Package is a deliverable or work component at the lowest level of its WBS branch. WBS Component: A component of a WBS which is located at any level.

A Work Breakdown Structure (WBS) (MIL-STD-881C) is a tool used to define a project in discrete work elements in a Hierarchical format. It displays and defines the product, or products, to be developed and/or produced. It relates the elements of work to be accomplished to each other and to the end product. In other words the WBS is an organized method to breakdown a product into subproducts at lower levels of detail. It's used for planning, cost estimating, execution and control.

The Work Breakdown Structure (WBS) is an outline for the project's Scope of Work and provides a numerical structure for organizing, sorting, and filtering the schedule and cost data for reporting purposes. A Work Breakdown Structure (WBS) provides the foundation matrix to relate the elements of scope, responsibility, schedule and cost. A Work Breakdown Structure (WBS) (MIL-STD-881C) is a tool used to define a project in discrete work elements in a Hierarchical format. It displays and defines the product, or products, to be developed and/or produced. It relates the elements of work to be accomplished to each other and to the end product.
The WBS is a means of organizing system development activities based on system and product decompositions. 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. The WBS is prepared from both the physical and system architectures, and identifies all necessary products and services needed for the system. This top-down structure provides a continuity of flow down for all tasks. Enough levels must be provided to properly define work packages for cost and schedule control purposes. [1]
Examples Of Wbs For Projects
A program WBS is established to provide the framework for program and technical planning, cost estimating, resource allocation, performance measurement, and status reporting. 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. Program offices develop a program WBS tailoring the guidance provided in MIL-HDBK-881 and MIL-STD-881C. The WBS is also an integral part of preparation of the Cost Analysis Requirements Description (CARD).
The Program Manager (PM) usually has the responsibility to develop an overall program WBS and to initiate development of contract WBSs for each contract in accordance with common DoD practice established in Mil-HDBK 881. The program WBS is the WBS that represents the total system and, therefore, describes the system architecture. The contract WBSs are part of the program WBS and relate to deliverables and tasks on a specific contract. The PM 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. As with most standards and handbooks, use of MIL-HDBK-881 cannot be specified as a contract requirement. 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. [1]
Wbs Work Breakdown Structure Template
The first three Work Breakdown Structure Levels are organized as:
- Level 1: Overall System
- Level 2: Major Elements (Segment)
- Level 3: Subordinate Components (Prime Items)
Contractor Work Breakdown Statement
The contract WBS is the Government – approved WBS for program reporting purposes and includes all program elements (for example, hardware, software, services, data, or facilities), which are the contractor's responsibility. It includes the contractor's discretionary extension to lower levels, in accordance with Government direction and the contract Statement of Work (SOW).
