Project Management Professional (PMP) Exam Practice – Question1338

Rather than use a WBS, your team developed a bill of materials to define the project's work components. A customer review of this document uncovered that a scope change was needed, because a deliverable had not been defined, and a change request was
written subsequently. This is an example of a change request that was the result of______________


A. An external event
B. An error or omission in defining the scope of the product
C. A value-adding change
D. An error or omission in defining the scope of the project

Correct Answer: B

Explanation:

Explanation:
The bill of materials provides a hierarchical view of the physical assemblies, subassemblies, and components needed to build a manufactured product, whereas the WBS is a deliverable-oriented grouping of project components used to define the total scope of
the project, providing a structured vision of what has to be delivered. Using a bill of materials where a WBS would be more appropriate may result in an ill-defined scope and subsequent change requests.
