"There are generally several dimensions and several issues at play in any negotiation. Wise negotiators explore all the issues and dimensions of a negotiation to find trade off areas and ways to enhance the ultimate agreement for all parties. Creative trade offs between the different assets, needs and preferences each party has are diligently examined to find ways to build new value. When the pie is successfully expanded, both parties leave with new value that was created purely from the process of negotiating. See Win-Win and Expanding the Pie."
