Get if: the art of negotiation without giving in, is the last book I’ve read, trafficking exclusively of negotiation, is of Roger Fisher, William Ury, and Bruce Patton. A wise and prudent agreement can be defined as one that approximates the legitimate interests of each of the parties to the greatest extent possible, resolves conflicts of interest fairly, is durable and takes into consideration the interests of the community. During the entire book discusses how to reach the best agreement for both parties through negotiation, speaks of different positions, of people, of interests, he cites real-life examples, etc. But something with that I stay of the entire book is Centrese on interests, not positions, the basic problem in a negotiation resides not in positions in conflict, but the conflict between needs, wishes, concerns and fears of each side, this chapter is that I liked and that more notes I took. The book is pretty good, but I must admit that there has been some chapters that I have been quite heavy, but there were interesting issues, questions to consider, and is in general advisable, especially for those who are professionally engaged in the negotiation.
