What does "D3" stand for?

The three Ds are dialogue, deliberation and decision making.  We use this name to emphasize that when groups and organizations work together on common problems or shared purpose, they need to be effective at all three Ds—dialogue for building shared understanding and mutual trust; deliberation for making the tough choices that most issues require; and decision making for reaching a conclusion in a way that creates legitimacy and widespread acceptance as a basis for effective, coordinated action.
