A lot of research has been conducted in order to investigate the suitable forms of leadership styles under specific circumstances. This essay deals with different leadership styles, their appropriate usage and as an example, it will use an evaluation and analysis of the case study of a person named Okuda, who has been the president of the car company Toyota and was famous for the drastic changes he made in the organization during his reign.Such a leadership style may be effective when the leader has all the information required for the decision-making process, is sure of what is needed to be achieved and how it can be achieved. It is also useful to be applied to a category of employees who are not trained enough to contribute to the decision making process.This approach can be used where the decision-making process is challenging and the leader alone is equipped with only partial information regarding the issue under consideration. It is effective for a class of employees who have ample knowledge regarding the issue and whose opinion if included can have strong impacts on organizational growth.This style as the name indicates is authoritarian in nature. According to Hersey and Blanchard (1982), cited in Breen (2002), directive leadership behaviour is typically a one-way process of communication in which the leader takes up the role of a dictator and orders the subordinates to do what he says. This style is suitable for tasks about which the leader is confident regarding the course to take to achieve the required targets.According to Goleman (2002), a coaching leader listens to the opinions of the subordinates involved while clearly assigning and defining the roles and tasks of all individuals involved. This leadership style is most appropriate when the subordinates are responsible individuals who have had exposure to similar situations in the past.
