From a speech by Tom Geddie of Central & South West Services
A business training exercise shows how people look at the same task in different ways. Draw an imaginary line on the floor, and put one person on each side. The purpose is to get one person to convince the other, without force, to cross the line. U.S. players almost never convince one another, but their Japanese counterparts simply say, "If you'll cross the line, so will I." They exchange places and they both win. That's not a bad illustration of the importance of cooperation as the world gets smaller and more complex.
