The lowest level of the work breakdown structure is called the _____.

• A. Scope Statement
• B. Work Package
• C. Task Analysis
• D. None of the Above

Answer: (B)

In a work breakdown structure, work is decomposed into progressively smaller components until you reach the smallest unit that can be planned, scheduled, and controlled. That lowest level is a work package. A work package defines a manageable chunk of work with its own scope, estimated duration, and cost, and it’s the unit you assign to resources and track for progress. The scope statement, while essential for outlining the overall project boundaries and deliverables, isn’t used as a granular planning unit within the WBS. Task analysis is a method for examining tasks or processes, not the formal WBS element used for organizing and controlling work at the lowest level. None of the above isn’t correct because the term work package specifically identifies this lowest WBS level.
