This includes many other successfully proven approaches and theories. In addition, the Harvard concept is globally applicable. Whether in the USA, Germany, China, or Russia, it has proven itself in practice all over the world, regardless of the circumstances. It has been validated as a university concept, and to this day it continues to be developed at the Program on Negotiation.
It is in the interest of all parties involved in a negotiation to apply the rules of a win-win concept and to focus their talks on cooperating, i.e. on working together rather than against each other. Competitive negotiation is more strenuous, costs more energy, and leads to winners and losers. The rule of thumb of the Harvard concept, on the other hand, offers satisfaction, stability, and creative possibilities. It thus enables relationships between the negotiating business partners that are geared toward the long term.
