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 it led to the need to write a change request. This is an example of a change request that is required because it is the result of-

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