This document discusses power in negotiation and its sources. It defines power as the ability to satisfy one's goals or desires in a given situation. There are two perspectives on power - power over others through domination, and power with others through cooperation.
The most important source of power is one's BATNA or best alternative to a negotiated agreement. Other sources include information and expertise, legitimate authority, control of resources and one's position in an organization's structure, personal attributes, and relationships and networks. Power also comes from the negotiation context and culture. When facing others with more power, tactics include avoiding all-or-nothing deals, constraining oneself, managing the process, and leveraging competition.
