When did business schools switch from winner/loser to winner/winner ?

I played a game at a development “camp” 50 years ago, in which four people competed to get the most stars. If you did one thing, you could earn twice as many stars as anyone else, but if you did, everyone else lost stars. And if any one else used the same strategy, you both lost double.

At the end of the game, the moderator added up all the stars from each foursome. The foursome with the most (showing the most cooperation) won the game.

The lesson was that if you cooperate to boost everyone, you all made more stars and you al prospered.

Business schools never taught “win/lose”.

@zenvelo Then what about further back? Before 1924’s from Mary Parker Follett?

If the players are fixed, you can get a good deal continually but you can get a great deal only once. No one is dumb enough to keep losing.

Don’t you just wish Politicians would follow this philosophy?
