Leadershipis a management function which is mostly directed towards people and social interaction, as well as the process of influencing people so that they would achieve the goals of the organization or the common goals. Without quality leadership and initiation of the members' activities, stimulation of high motivation and engagement of people, there is no successful organization nor successful company. Experience has shown that managerial efficiency differs depending on the managers' leadership style.

Leadership styles have a significant influence upon operational efficiency, especially if we observe them in a contingency context. Although some authors (for example: Hall 1977, Brady and Helmich 1984, House and Singh 1987, and others) hold that leadership styles of management do not have a decisive influence upon work efficiency and corporate performance - such a standpoint, at least according to the data available to us - is not the standpoint of the majority. Although there still is no uniform answer to the question of which leadership style is the most efficient, the research so far has shown that the leadership style is the cause, and not the consequence of the company's performance, and that there are significant differences in leadership, monitoring, interpersonal relationships, application of methods, communication and other management components between successful and unsuccessful managers, that is between organizational units which they are at the head.
