I've facilitated several workshops focused on helping members within a team align on roles and responsibilities, build RACI charts, and expectations matrixes. But I'm faced with a new challenge: Helping members across multiple teams (3 different teams within the same organization), align on roles and responsibilities related to managing and engaging external ambassadors/supporters. The ideal outcome would be identifying one of the 3 teams as the "hub" or "Center of Excellence" responsible for governance and oversight perhaps even an enterprise calendar, while permitting the other 2 teams to engage ambassadors independently. Any ideas as to how to lead this group to alignment, knowing that two of the teams may need to give up a little of their current autonomy?
