Negotiation is a specialized and formal version of conflict resolution most frequently employed when important issues must be agreed upon. Negotiation is necessary when one party requires the other party's agreement to achieve its aim. The aim of negotiating is to build a shared environment leading to long-term trust and often involves a third, neutral party to extract the issues from the emotions and keep the individuals concerned focused. It is a powerful method for resolving conflict and requires skill and experience. Zartman defines negotiation as 'a process of combining conflicting positions into a common position under a decision rule of unanimity, a phenomenon in which the outcome is determined by the process.' Druckman (1986) adds that negotiations pass through stages that consist of agenda setting, a search for guiding principles, defining the issues, bargaining for favorable concession exchanges, and a search for implementing details. Transitions between stages are referred to as turning points.
