Victor Vroom, a professor at Yale University and a scholar on leadership and decision-making, developed the normative model of decision-making. [1] Drawing upon literature from the areas of leadership, group decision-making, and procedural fairness, Vroom’s model predicts the effectiveness of decision-making procedures. [2]
This model suggests the selection of a leadership style of groups decision-making. Leader Styles. The Vroom-Yetton-Jago Normative Decision Model helps to answer above questions. This model identifies five different styles (ranging from autocratic to consultative to group-based decisions) on the situation and level of involvement. They are:
They used this in a normative decision model in which leadership styles were connected to situational variables, defining which approach was more suitable to which situation. [63] This approach supported the idea that a manager could rely on different group decision making approaches depending on the attributes of each situation.
The mythological Judgement of Paris required selecting from three incomparable alternatives (the goddesses shown).. Decision theory or the theory of rational choice is a branch of probability, economics, and analytic philosophy that uses the tools of expected utility and probability to model how individuals would behave rationally under uncertainty.
Among these approaches are contingency theory, the consideration and initiating structure model, leader-member exchange or LMX theory, path-goal theory, behavioural modification and transformational leadership theory. Contingency theory indicates that good leadership depends on characteristics of the leader and the situation. [41]
The decision maker assesses different alternatives by their utilities and the subjective probability of occurrence. [58] Rational decision-making is often grounded on experience and theories that are able to put this approach on solid mathematical grounds so that subjectivity is reduced to a minimum, see e.g. scenario optimization.
In reviewing the older leadership theories, Scouller highlighted certain limitations in relation to the development of a leader's skill and effectiveness: [3] Trait theory: As Stogdill (1948) [4] and Buchanan & Huczynski (1997) had previously pointed out, this approach has failed to develop a universally agreed list of leadership qualities and "successful leaders seem to defy classification ...
When a decision or conclusion has to be made through complex information, human decision-makers often fail to comply with normative decision theories. Moreover, a person's lifestyle, social interactions and collective behaviors have a clear influence on their decisions.
