The Work Breakdown Structure Is...
Product-oriented hierarchy of goods and services.
Form: inverted tree; or indented list.
Visualizing the entire project.
Common framework for planning and control.
Vehicle to divide work into tasks that are:
Manageable
Independent
Measurable
Integratable
Graphically displays entire project. Clear definition of all effort.
Top Assembly Drawing of the project.
Product Breakdown Structure or Project Breakdown Structure moreapt name! Or perhaps Work Buildup Structure.

WBS is The Basis For......
Cost estimates and budgets.
Milestones & schedules.
Responsibility assignment.
Allocation of resources.
Schedule horizontal and vertical traceability.
Risk analysis.
Concurrence of participants.
Integrating the total project effort.
Summarizing costs, schedules, performance.
Forcing the Project Manager to think through all elementsof the project.

Tests for a Good WBS:
Product-oriented hierarchy of goods and services.
Top level may be dictated by contract.
Basis for cost estimating, project organization, assigning responsibility,task scheduling, and status reporting.
Basis for understanding and communication.
Each element should be manageable.
Based on System Engineering: interfaces are minimized; units are
stand-alone testable. Eliminating one product element will delete the associated costs.
Segregate recurring from non-recurring costs.
Identifies and defines all effort to be expended: correlation of lowerlevels to specification tree, contract line items, data items, and work
statement tasks. Useful! Reflects the way the work is managed and performed.
Sufficiently low level to establish adequate visibility and confidence forcost estimating, project planning, and project control.
Technical/cost/schedule can be integrated at every level for each
element. WBS Definition

Elements Not to Include in WBS
Do not use the structure of the contractors organization as the basis
of a WBS. At the top levels do not begin by decomposing into the functions or
cost categories associated with developing those products.
Adapted fromDepartment of Defense HandbookWork Breakdown Structure, MIL-HDBK-881.Available at:http://www.acq.osd.mil/pm/newpolicy/wbs/wbs.html.
Includes examples from the defense industry.
Program
Design Build Test
Hardware Software
What not to do!
Do not use generic names -- use actual system names andnomenclature.
No disembodied software -- software developed to reside on specificequipment must be identified as a subset of that equipment.
