In most companies those 10 managers are not a team, unfortunately. It's more like there's a "top" manager who has 10 separate sub managers of 10 teams. But those sub managers are mostly independent. At least that's how it is in most places, communication between middle managers goes up and down, not sideways.

What I'm talking about is different, it's not just 10 managers that "have to talk", it's 10 managers in the same team with the same goal. They just happen to each coordinate another 10 person team. I haven't really seen that done anywhere, but I've seen some chair shuffling that approximated it. Would love to see it taken to the logical conclusion.
