I was on a big project in the early aughts (pure XP, pairing, tickets, stories, tests (40,000 of them at the end) etc), on which, we were contractually obliged to A. hire on at least 4 accenture consultants, and B. purchase 4 rational rose seats.
We simply stuck the accenture clowns alone in a room with rational rose, and we never heard from them again (nor did we ever see any uml). Best case scenario.
