Note !
The WBS is not the project plan, theschedule, or even the activity list. You
will use the WBS to help you schedule
and assign resources. A WBS is aprocess, as well as a visual
representation of the work, to help you
organize and plan the action that mustbe completed for the project to come
to an end.
