DEFINATION OF WBS:-

The work Breakdown Structure(WBS) is a hierarchical description of the work that must be done to complete the Project,as defined in the Project over view Statement.(POS).Several processes can be used to create this hierarchy.

Q.Explain briefly the Approaches to build/generate the WBS?

There are two main Approaches to build/generate WBS:-

1. TOP-DOWN APPROACH

2. BOTTOM-UP APPROACH.

CRITERIA TO ENSURE COMPLETENESS OF EACH ACTIVITY IN WBS.

Developing the WBS is the most critical part of the JPP session. If we do this part right, the rest is comparatively easy. How do you know that you’ve done this right? Each activity must possess six characteristics to be considered complete. That is, completely decomposed. The six characteristics are as under:

CHAPTER 4-3

SIX CRITERIA TO TEST FOR COMPLETENESS IN THE WBS

1. Status/completion is measurable. (Measurable Status) 2. Start/end events are clearly defined.

(Bounded)3. Activity has a deliverable.4. Time/cost is easily estimated.5. Activity duration is within acceptable limits.6. Work assignments are independent.

CHAPTER 4-4

If the activity does not possess these six characteristics, decompose the six activity and ask the questions again. As soon as an activity possesses the six characteristics, there is no need to further decompose it. As soon as every activity in the WBS possess these six characteristics, the WBS is defined as complete.
