1MANAGEMENT OF ENGINEERING PROJECT MANAGEMENT Work breakdown structure (WBS)
2Terms and Definitions Project Charter Project Creep A document authorizing the project manager to initiate and lead the project.Project CreepThe tendency for the project scope to expand over time due to changing requirements, specifications, and priorities.
3Establishing Project Priorities Causes of Project Trade-offsShifts in the relative importance of criterions related to cost, time, and performance parameters. Also, called triple constraintBudget– CostSchedule– TimePerformance– Scope
5The Work Breakdown Structure (WBS) The WBS picture a project subdivided into hierarchical units of tasks, subtasks, work packages, etc.The outcome of this hierarchical process is called the work breakdown structure (WBS).The WBS is a map of the project.
6Creating the WBS Work Breakdown Structure (WBS) Defines the relationship of the final deliverable (the project) to its subdeliverables, and in turn, their relationships to work packages.Basically, the WBS is an outline of the project with different levels of detail.
7Hierarchical Breakdown of the WBS Major deliverables
8subdeliverable is further divided into work packages subdeliverable is further divided into work packages. Because the lowest subdeliverable usually includes several work packages.the work packages are grouped by type of work—for example, hardware, programming, testing.These groupings within a sub deliverable are called cost accounts. This grouping facilitates a system for monitoring project progress by work, cost, and responsibility.
9The Work Breakdown Structure The WBS is an important document and can be tailored for use in a number of different waysIt may illustrate how each piece of the project contributes to the whole in terms of performance, responsibility, schedule, and budgetIt may list the vendors or subcontractors associated with specific tasks
10The Work Breakdown Structure It may serve as the basis for making cost estimates or estimates of task durationIt may be used to document that all parties have signed off on their various commitments to the project
11Deliverables There are many deliverables in a project. Well defined deliverables eliminate scope creep.
12Deliverables Deliverables are the results produced by tasks. For example, in house constructions deliverables could be the house foundation, walls, roof, and electrical work, etc.

15Integrating WBS with the organization Organizational Breakdown Structure (OBS)Depicts how the firm is organized to discharge its work responsibility for a project.Identifies organization units responsible for work packages.Ties the organizational units to cost control accounts.
17Coding the WBS for the Information System WBS Coding SystemDefines:Levels and elements of the WBSOrganization elementsWork packagesBudget and cost informationAllows reports to be consolidated at any level in the organization structureThe most commonly used scheme in practice is numeric indention.
20WBS A badly designed WBS can result in: Incomplete project definition. Missed deadlines on deliverables or timeline slippage.Budget cost overruns.Frequently changing scopeUnusable productFailure to deliver on some aspects of project scope
