During project executing, a large number of changes are made to the project. Several of the change requests have come from the customer, significantly changing the functionality of the originally requested product. Six project team members have been reassigned by management to a higher- priority project, and they have been replaced. As project work has progressed, many of the identified risks have occurred and have been successfully mitigated. However, three contingency plans have been adjusted and will be implemented if identified risks recur during the remainder of the project. The project manager should: A. Wait until all changes are known, and then print out a new schedule B. Make sure the project charter is still valid C. Change the schedule baseline D. Talk to management before any changes are made
