Synergy: the third alternative

The published recipe for finding a third alternative: (1) Define the problem from both parties' frames, fully, until each can restate the other's frame to satisfaction. (2) Brainstorm together for the third alternative — explicitly looking for solutions neither party walked in with. Suspend judgment; volume first, evaluation second. (3) Recognize the third alternative when it appears — both parties say "that's better than what I had." If nobody says it, keep brainstorming or accept No Deal; don't settle for compromise and call it synergy.
