Vroom`s Decision Tree

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
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
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
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.
