This document outlines three approaches for dealing with difficult negotiations: principled negotiation, negotiation jujitsu, and one-text mediation. Principled negotiation involves separating people from problems, focusing on interests rather than positions, generating options, and using objective criteria. Negotiation jujitsu recommends not rejecting, defending, or counterattacking the other party, but instead understanding their interests and considering their positions as alternatives. One-text mediation uses a trained mediator to simplify the decision-making process by identifying interests, reducing decisions needed for agreement, and having the parties critique and improve a written list.
