You have recently been placed in an apprenticeship program in the input procurement department of a kitchen construction company. From reputation, you know that your supervisor likes to give little "pop quizzes" on understanding various aspects of your job. He catches you in the elevator one day, and immediately begins:

"Tell me, what conditions would be necessary for us to move from our existing contract with our marble supplier to a serious move toward absorbing their company in-house?"

What would you tell him?
