Back-and-forth communication designed to reach an agreement between two or more parties with some interests that are shared and others that may conflict or simply be different. Negotiation is an intrinsic part of any kind of joint action, problem solving, and dispute resolution, and may be verbal, nonverbal, explicit, implicit, direct, or through intermediaries. (Michael L. Moffitt and Robert C. Bordone, eds., Handbook of Dispute Resolution [Program on Negotiation/Jossey-Bass, 2005], 279)
