Although each of the four factors of the SLT may be found in the literature within other leadership theories and/or models, a distinctive feature of the SLT is that, observed in tandem, the four factors are equalized and interactive without hierarchical rank. Examples of some traditional theories that include parts of the SLT’s four factors are: (a) the Ohio State studies, (b) the University of Michigan studies, (c) the managerial grid, and (d) situational leadership. While in these four theories, components or aspects of one or more of the four factors may be present, they exist either in isolation or in part or in a hierarchical arrangement.
Regarding leadership, in the Ohio state studies (Halpin & Winer, 1952; Hemphill & Coons, 1950), leadership is bifurcated into initiating structure and consideration and is suggested to be a style approach to leading subordinates in certain situations. The SLT, however, includes a range of leadership behaviors, as opposed to a broader leadership style, and considers organizational structure, external forces, and values, attitudes, and beliefs as each of those factors interacts with leadership behaviors. In the University of Michigan studies (Likert, 1961), the term, leadership behaviors, is mentioned; however, it consists of only two behaviors-- employee orientation and production orientation. Further, the Michigan studies theory does not take into account a range of behaviors related to various situations, including time, place, and relationships, as does the SLT. An additional theory, Blake and Mouton’s (1968) original managerial grid, focuses on identifying one of five leadership styles with relation to production versus people orientation. However, there are no specific generalizations relating a specific style to a particular situation. In contrast, in the SLT, the leadership behaviors are related to the organizational structure, to attitudes, values, and beliefs, and to external forces which comprise the situation within which the leader finds him/herself. Although the Hersey and Blanchard (1969) situational leadership model does relate leadership to situations, it focuses on leadership style and on the development level of the subordinates as noted in dyadic terms, with leaders interacting with employees in a given situation and adapting their style to match the development level of the employee. The SLT, however, takes the stance that leadership behavior is active and dynamic, interacting with organizational structures, values, attitudes, and beliefs, and external forces. In the Hersey and Blanchard situational leadership model, it is incumbent upon the leader to adapt to the employee. Conversely, in the SLT, several alternatives are available in order for the leader and the organization to accomplish purposes or goals. The leader may (a) adapt by altering leadership behavior based on a broad scan of all four factors, (b) attempt to alter the organization and external forces, or even modify attitudes, values, and beliefs of colleagues, or (c) analyze the situation with a systemic view of the four factors and determine that the position he/she finds him/herself in is not a fit. If this is the case, the leader may choose to leave the position and/or organization.
