Sally and Joe are two project managers working in the corporate offices of a popular fast$-$food franchise. They $$re both studying for their PMP ${?}^{}$ certification and are having a discussion on the WBS$.$ Sally is confused and asks Joe to describe what the WBS contains. What is Joe likely to respond with?

The WBS is a work package containing unique identifiers, which provide a structure for hierarchical summation of costs, schedule, and resource information.

The WBS is a document that provides detailed deliverable, activity, and scheduling information about each component within the project scope statement.

The WBS is a decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables.

The WBS includes a description of the project scope, major deliverables, assumptions, and constraints.
