Stuart Diamond, a professor at the Wharton School of Business and one of the world's most sought-after negotiation experts, offers a workable negotiation framework that will help you get your way and then some, in everything from buying a bicycle to negotiating a business merger. The Key to Negotiation , in his opinion, is a very clear understanding of his goal and the goal of his opponent. In this case, you can maneuver, find new non-standard ways to achieve what you want, and you can offer your opponent exactly what he is waiting for (or an equivalent replacement). And when the overall negotiating pie gets bigger, your pieces get bigger too.
