Rachael is the project manager for a large project in her organization. A new change request has
been proposed that will affect several areas of the project. One area of the project change impact is
on work that a vendor has already completed. The vendor is refusing to make the changes as they’ve
already completed the project work they were contracted to do. What can Rachael do in this
instance?

Threaten to sue the vendor if they don’t complete the work.

B.
Fire the vendor for failing to complete the contractual obligation.

C.
Withhold the vendor’s payments for the work they’ve completed.

D.
Refer to the contract agreement for direction.

Explanation:
There could be many reasons why the vendor is refusing to do the new work, but chief among them
is that they’ve completed their contractual obligations. They could have already moved their crew to
new projects and aren’t available for more work at the present time, the question just doesn’t say.

work caused by the project change.

abide by the contract.
Answer option B is incorrect. The vendor has already completed their contractual obligation.
