This chapter introduces key concepts about negotiation. It defines negotiation as situations involving two or more interdependent parties who are seeking agreement rather than fighting, capitulating, or taking their dispute to a third party. Negotiations can be either distributive, where one party wins what the other loses, or integrative, allowing mutual gains. Conflicts arise from divergent interests but can have benefits if managed constructively through open communication and understanding different perspectives. The chapter outlines different levels and styles of conflict management.
