However, if you need to resolve a major disagreement, then make sure you prepare thoroughly. Using our free worksheet, think through the following points before you start negotiating: what do you want to get out of the negotiation? What do you think the other person wants? What do you and the other person have that you can trade? What do you each have that the other wants? What are you each comfortable giving away? If you dont reach agreement with the other person, what alternatives do you have? Are these good or bad? How much does it matter if you do not reach agreement? Does failure to reach an agreement cut you out of future opportunities? And what alternatives might the other person have? What is the history of the relationship? Could or should this history impact the negotiation? Will there be any hidden issues that may influence the negotiation? How will you handle these?
