BATNA Quotes in Getting to Yes
If the other side has big guns, you do not want to turn a negotiation into a gunfight. The stronger they appear in terms of physical or economic power, the more you benefit by negotiating on the merits. To the extent that they have muscle and you have principle, the larger a role you can establish for principle the better off you are.
Having a good BATNA can help you negotiate on the merits. You can convert such resources as you have into effective negotiating power by developing and improving your BATNA. Apply knowledge, time, money, people, connections, and wits into devising the best solution for you independent of the other side's assent. The more easily and happily you can walk away from a negotiation, the greater your capacity to affect its outcome.
