Project Management Professional (PMP) — Question 883

A construction company recently won the bid for a project to build a cable bridge. A project charter has been prepared and a project manager has been assigned. The project manager is creating a work breakdown structure (WBS) for the project.

To what level should the project manager decompose their project?

Answer options

• A. To the lowest level where cost and duration can be estimated and managed
• B. To the level where the highest level of quality is maintained
• C. To level four of the schedule for bridge construction
• D. To the level where the bridge can be constructed safely

Correct answer: A

Explanation

The correct answer is A because the work breakdown structure should be detailed enough to allow accurate estimation of costs and durations, which is essential for effective project management. Options B, C, and D do not focus on the practical aspects of project management related to cost and duration estimation, making them less suitable for the WBS decomposition requirement.
