An overview of the topic of leadership styles summarizes that the existing studies on how performance is affected by leadership style is separated into important phases. Early studies on leadership (frequently categorized as ‘trait’ studies on leadership) concentrated on identifying the personality traits which characterized successful leaders (Argyris, 1955; Mahoney et al., 1960).
According to them successful leaders are ‘naturally born’ and those they have certain native characteristics which distinguish them from non-leaders (see Stodgill, 1948). However, there was significant difficulty in validating these characteristics led to widespread criticism of this trait approach, signaling the emergence of ‘style’ and ‘behavioral’ approaches to leadership (Stodgill, 1948). Style and behavioral theorists shifted the emphasis away from the characteristics of the leader to the behavior and style the leader adopted.
The primry conclusion of these studies is that adoption of democratic or participative styles by leaders are more successful (see, for example, Bowsers and Seashore, 1966). In this sense, these early studies are focused on identifying the ‘one best way of leading’.
Similarly to trait theories, the major weakness of style and behavioral theories is the ignorance of how important role situational factors play in determining the effectiveness of individual leaders (Mullins, 1999). It is this limitation that gives rise to the ‘situational’ and ‘contingency’ theories of leadership (for example, Fiedler, 1967; House, 1971; Vroom and Yetton, 1974) which shift the emphasis away from ‘the one best way to lead’ to context-sensitive leadership. Although each study emphasizes the importance of different factors, the general tenet of the situational and contingency perspectives is that leadership effectiveness is dependent on the leader’s diagnosis and understanding of situational factors, followed by the adoption of the appropriate
