Negotiators who have constituents are usually involved in three or four distinctly different relationships and often in two separate and distinct negotiations.

Audiences: Individuals or groups who are not directly involved in a negotiation, but can observe and react to the events.
Coalitions: Alliances between individuals or groups who cooperate for a common cause. 

To identify target audience behavior, you can:
Categorize your audiences
Divide audiences into categories
Primary: Those whose behavior you are trying to change
Influencers: Those that can influence the primary audience
Gatekeepers: Those that can facilitate or prevent access to the primary audience
