To evaluate an option from the other side’s point of view, consider how they might be criticized if they adopted it. Write out a sentence or two illustrating what the other side’s most powerful critic might say about the decision you are thinking of asking for. Then write out a couple of sentences with which the other side might reply in defense. Such an exercise will help you appreciate the restraints within which the other side is negotiating. It should help you generate options that will adequately meet their interests so that they can make a decision that meets yours.
