The Thomas Kilmann model of conflict is helpful in demonstrating that good teams need people who are focused both on their individual task and the greater good of the team. Leaders don’t need to be “Yes” men – in fact having yes men just means they accede to your every request, which in turn means your overall team is only as good as you. I think many church teams end up competing, compromising, avoiding, or accommodating. Collaboration is the goal. For that to happen you need team players who will assert themselves.
