22. Define Work Breakdown Structure (WBD) and the way in which it influences task/activity work estimates?
The work breakdown structure describes the project's work activities as well as the sub-activities for each work requirement. The breakdown is broken down into tiers where all of the work that needs to be done is evident. Work does not need to be broken down any further. Additional data that assist describe the tasks are included in the work breakdown dictionary. When all aspects of the work and dependencies are known, time and effort estimations can be correct.
