If people do not know the boundaries, a few of them will go off like loose cannon, making undeliverable commitments and spending money like water. Most, however, knowing full well that there are boundaries somewhere, will stay rooted to the spot and do nothing. Specifying boundaries is like marking out minefields – it enables the troops to use the space between them. If they are known or even rumored to be there, but are unmarked, advances usually come to a halt.
