Negotiation is a process where parties try to reach an agreement or compromise on issues in dispute. It involves exchanging offers and counteroffers to find mutually acceptable solutions. Effective negotiation requires preparation, understanding both sides' objectives and priorities, developing alternative options, and using strategies like focusing on interests rather than positions to achieve win-win outcomes when possible. Key roles for negotiators include maintaining team unity, understanding the issues, preparing necessary information, seeking compromise, and knowing when to conclude the negotiation. Personality traits alone do not determine outcomes, but both gender and power can influence negotiating style and perceived success.
