W

Work breakdown structure (WBS) A deliverables-oriented hierarchy that defines the total work of the project. Each level has more detailed information than the previous level.

Work effort The total time it would take for a person to complete the task if they did nothing else from the time they started until the task was complete.

Work package The lowest level in a WBS. Team assignments, time estimates, and cost estimates can be made when this level represents tasks or activities. On very large projects, this level is handed off to subproject managers who develop their own WBS to fulfill the requirements of the work package deliverable .
