I'll ask the vendor for ballpark prices to see if the idea is feasible. "You can't talk with vendors until our change control board approves the project." "But that would require a cost-benefit analysis." "And I can't do that without ballpark prices from the vendor." "Just take your best guess." "So...I should make up a number so I can get approval to make a phone call and ask what the number should have been?" "Right. But first you need to get my approval to do the cost-benefit analysis." "Will you approve it?" "I'd have to see the numbers."
