1. MANAGEMENT OF ENGINEERING PROJECT MANAGEMENT
Work breakdown structure (WBS)

2. Terms and Definitions Project Charter Project Creep
A document authorizing the project manager to initiate and lead the project.
Project Creep
The tendency for the project scope to expand over time due to changing requirements, specifications, and priorities.

3. Establishing Project Priorities
Causes of Project Trade-offs
Shifts in the relative importance of criterions related to cost, time, and performance parameters. Also, called triple constraint
Budget– Cost
Schedule– Time
Performance– Scope

4. Project Management Trade-offs

5. The 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.

6. Creating 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.

7. Hierarchical Breakdown of the WBS
Major deliverables

8. subdeliverable 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.

9. The Work Breakdown Structure
The WBS is an important document and can be tailored for use in a number of different ways
It may illustrate how each piece of the project contributes to the whole in terms of performance, responsibility, schedule, and budget
It may list the vendors or subcontractors associated with specific tasks

10. The Work Breakdown Structure
It may serve as the basis for making cost estimates or estimates of task duration
It may be used to document that all parties have signed off on their various commitments to the project

11. Deliverables There are many deliverables in a project.
Well defined deliverables eliminate scope creep.

12. Deliverables Deliverables are the results produced by tasks.
For example, in house constructions deliverables could be the house foundation, walls, roof, and electrical work, etc.

14. Work Breakdown Structure

15. Integrating 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.

16. Integration of WBS and OBS

17. Coding the WBS for the Information System
WBS Coding System
Defines:
Levels and elements of the WBS
Organization elements
Work packages
Budget and cost information
Allows reports to be consolidated at any level in the organization structure
The most commonly used scheme in practice is numeric indention.

18. WBS Coding

19. WBS badly designed
Possible reasons

20. WBS A badly designed WBS can result in: Incomplete project definition.
Missed deadlines on deliverables or timeline slippage.
Budget cost overruns.
Frequently changing scope
Unusable product
Failure to deliver on some aspects of project scope
