Vroom’s Decision Tree Vroom and Yetton’s Model • Five different types of decision making which vary according to the amount of subordinate influence • One extreme: Unilateral decision-making by the manager • Other extreme: Participative decision making The Five Decision Types • AI: You make the decision with currently available data • AII: Necessary information is obtained from subordinates, but you still decide alone. Your subordinate’s role is to provide information data only; they have nothing to do with generating or evaluating alternatives The Five Decision Types • CI: You discuss the problem with relevant subordinates individually. Then, without bringing them together, make a decision that may or may not reflect their output. • CII: You share the problem with subordinates in a group meeting, gathering ideas and suggestions, then make the decision alone, which may or may not take the input of the group meeting into account. The Five Decision Types • GII: Problems are shared with the group. In this case, you would be using the participative management style. Your role is to provide information and help, facilitating the group’s determination of its own solution rather than the solution preferred by the manager.
