The parties then bargain from their separate opening positions to agree on one position. Haggling over a price is a typical example of positional bargaining. Fisher and Ury argue that positional bargaining does not tend to produce good agreements. It is an inefficient means of reaching agreements, and the agreements tend to neglect the parties' interests. It encourages stubbornness and so tends to harm the parties' relationship.
Principled negotiation provides a better way of reaching good agreements.
Fisher and Ury develop four principles of negotiation. Their process of principled negotiation can be used effectively on almost any type of dispute. These principles should be observed at each stage of the negotiation process. The process begins with the analysis of the situation or problem, of the other parties' interests and perceptions, and of the existing options. The next stage is to plan ways of responding to the situation and the other parties.
