Negotiation is a dialogue between two or more people or parties intended to reach a beneficial outcome over one or more issues where a conflict exists with respect to at least one of these issues. This beneficial outcome can be for all of the parties involved, or just for one or some of them. It is aimed to resolve points of difference, to gain advantage for an individual or collective, or to craft outcomes to satisfy various interests. It is often conducted by putting forward a position and making concessions to achieve an agreement. The degree to which the negotiating parties trust each other to implement the negotiated solution is a major factor in determining whether negotiations are successful. People negotiate daily, often without considering it a negotiation. Negotiation occurs in organizations, including businesses, non-profits, and within and between governments as well as in sales and legal proceedings, and in personal situations such as marriage, divorce, parenting, etc. Professional negotiators are often specialized, such as union negotiators, leverage buyout negotiators, peace negotiator, or hostage negotiators. They may also work under other titles, such as diplomats, legislators, or brokers.
