Managers in the deliberation theory are members of the group that are responsible for decision making and making the group move in the decided direction. In order to achieve their goals they have to be good at decision making and in their ability to motivate and supervise other members to advance along the lines of decisions made by the managers.
I suspect that Managers in big organizations will be more of the A type (also called alpha dominance or doers). The Type A managers will be goal orinted and there fore will stress the system.They will consult less with their workers.
