The document discusses the work breakdown structure (WBS) and approaches for generating a WBS. It explains that a WBS is a hierarchical description of the work needed to complete a project. There are two main approaches for building a WBS: top-down and bottom-up. It also outlines six criteria for ensuring activities in a WBS are fully decomposed - including having measurable status, defined start/end events, a deliverable, estimable time/cost, appropriate duration, and independent work assignments. Activities should be further broken down until all six criteria are met, indicating the WBS is complete.

1. 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.

4. 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.

5. 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:

6. 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.

7. 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.
