WBS viewpoints

Hi PS gurus!

Can anyone explain me in details about WBS various viepoints with some examples:

You can structure the WBS from various viewpoints:

By phase (logic or process oriented)

By function (function-oriented)

By object (object-oriented)

Regards,

ANSAR

    Take an example

    Project definition: Construct a Gas Pipeline

    Level 1 WBS: Construct a Gas Pipeline

    Option1 - based on function

    L2 Electrical

    L3 HT

    L3 LT

    L2 Mechanical

    L3 Static

    L3 Rotary

    L2 Civil

    L3 Clearing Grading

    L3 Backfill

    Option 2 - based on phases

    L2 Phase 1

    L3 Clearing Grading

    L3 Pipe Coating

    L2 Phase 2

    L3 Trenching

    L3 Pipe Laying

    L2 Phase 3

    L3 Backfilling

    L3 Restoration

    Option 3 - object wise say project manager

    L2 project manager Jack

    L3 Pipe Laying

    L3 Pipe Coating

    L2 Project Manager Jill

    L3 Clearing & Grading

    L3 Backfill

    L2 Project Manager John

    L3 Trenching

    L3 Restoration

    As you can see the same project can be represented in different ways depending on the requirement. This requirement is usually finane driven as they dictate the requirements for the costing buckets (= WBS) that need to be set up

    Phase Based structuring

    like as engineering, procurement, assembly. this type of structuring well suited for time scheduling and step by step execution of project.

    Funcation based structuring

    This structuing method may comprise WBs for individual assemblies of say elevator, such as motor, shaft, cabin parts, if you are using the project stock than those WBS eanbales you to keep separate stocks for your diff. assemblies.

    By object (object-oriented)

    Individual structure can contain single WBS for SD, Purchasing & production. they can be separeated by responsible cost centers. in reporting thsi type of structuring allows direct evaluation of cost portions to diff. org units.

    I think,we should pay attention based on which aspects we would like to see our reports while structuring.
