Applying Management Tools to a Project Work Breakdown

Applying Management Tools to a Project Work Breakdown Structure

Work Breakdown Structure (WBS) WBS: • Defines the total system to be developed or produced. • Relate the elements of work to be accomplished to each other and to the end product. • Is displayed as a product oriented family tree composed of hardware, software, services, data and facilities which defines the total program. • Standard: Mil Hdbk-881

Basic Purposes of Work Breakdown Structure ORGANIZATIONAL • Provides Structure for Assigning Multi-Disciplinary Product Teams TECHNICAL • Shows the System and its Subsystems as a Product Tree • Product Tree aids: Interface Identification & Control Specification Development • Provides a Structure: Work Assignment Material/Part Ordering • Configuration Items must be traceable to WBS BUSINESS • Provides Structure for Budgets and Cost Estimates • Collect and Analyze Costs to track Budget

The Anatomy of a WBS A WBS has a Product Part and a Process Part. • Product part of the system – Products delivered to the operational customer. – Design (Physical) architecture. • Process part of the system – Efforts required to develop, produce and support products. – Execution of the IPT primary function process elements.

WBS Development • Ensure all applicable work is represented. • Enough levels provided to identify work packages for control purposes. (usually levels 0, 1, 2) • Duplication of work eliminated. • If too few levels identified - management visibility and integration of work packages may be difficult. • If too many levels - too much time may be wasted in performing program review and control actions.

WBS Levels Level Zero- Overall System (derived from Functional level 0) The entire Program Example: EE 321 X course (Robots and C&C Essay) Level One- Subsystems (derived from Functional level 1) Major System(s) Examples: Recycling Robot (competition) – C&C Reflective Essay Level Two- Components (derived from Functional level 2) Subsystem(s): Recover, Move, Store, Sort ……, Research, Select, Reflect, Review, Draft, Write For Program Managers, levels 1 -3 are of prime importance

Work Package Defines: • The work required. • Functional responsibility for performance. It is a specific task or set of tasks to be accomplished to produce a: -Drawing, -Design, -Piece of hardware or service.

WBS Summary WBS development is a systems engineering responsibility. – Total system described through a logical breakout of elements into work packages. – Tool for planning and assignment of tasks and work packages. – Assists in tracking resource expenditure, schedule, and technical performance. – Must be developed to appropriate level and represent all applicable work.
