Over the years, researchers have developed the following theories about leadership:
- Trait
- Behavioral
- Contingency
- Transformational
Trait theories were developed in the 1920s and 1930s and focused on identifying characteristics that differentiated leaders from non-leaders. These theories focused on “what” an effective leader is, but didn’t identify “how” leaders led. This approach assumes certain physical, social and personal characteristics are inherent in all leaders. Sets of traits and characteristics were identified to assist in selecting the right people to become leaders. Physical traits include things like age, height and appearance. Social characteristics include charisma, tactfulness and popularity. Self-confidence, adaptability and assertiveness are examples of personality. Finally, task-related characteristics include drive and initiative.
The trait theory is still used today. When a manager interviews potential employees, he is assessing whether or not the prospective employee has “what it takes” to make it in the organization. The manager considers the candidates appearance, education and responses to questions in making the decision whether of not to hire the individual. This approach is relevant to an extent because it allows the manager to develop an impression of the prospective employee based on a limited amount of information. However, trait theory doesn’t distinguish a leader from a follower, the situation does.
Behavioral theories propose that leadership can be taught. Researchers developed leadership behavior determinants, so managers could be trained to be leaders. For example “theory X and Y” represent the different ways the manager views employees. The “theory X” manager believes employees are motivated by money; whereas the “theory Y” manager believes that employees are motivated by some intrinsic force. In this instance, the manager would determine which employee view he used and could adapt his leadership style to compensate.
The key to behavioral theory is that the manager knows himself. Knowing personal strengths and weaknesses is important to successful leadership. The leader must recognize his capabilities and limitations. Former Chief Master Sergeant of the Air Force, Robert D. Gaylor said,
“Sure, everyone wants to be an effective leader, whether it be in the Air Force or the community. You can and will be if you identify your strengths, capitalize on them and consciously strive to reduce and minimize the times you apply your style inappropriately.
The contingency leadership theory involves adapting behavior to meet the needs of the people relevant to a particular managerial situation. Contingency theory adds the environment to the leadership situation. How leaders adapt their style to the demands of the environment will ultimately determine their effectiveness. This theory was the result of Fred Fiedler’s 40-year study of leadership and organizational effectiveness.
Fiedler’s theory states that there is not just one way for a manager to lead. The situation the manager encounters at any given time will determine which style he uses. In an environment where the tasks performed are routine in nature (i.e. telemarketing), a leadership style may be employed that would not be as effective in a more dynamic (i.e. clinical research) environment.
In developing this theory Fiedler determined that managers were either task-centered or relationship-centered. Task-centered managers may do better in a more formalized environment with centralized authority. The relationship-centered manager may have an advantage in organizing teams to accomplish a task. Both managers can be equally effective and the key is to adapt your style (i.e. task, relationship or a combination of both) to environmental demands.
A logical development of contingency theory is Ken Blanchard’s situational leadership theory. Blanchard takes Fiedler’s theory one-step further by incorporating the maturity of the follower (i.e. willingness to perform the task) to the application of leadership style. Contingency and situation leadership are transactional, in that managers guide followers by clarifying the role and task requirements.
Finally, transformational leadership theory is a mixture of trait and behavioral theories. Unlike situational leaders, who are transactional, transformational leaders are charismatic visionaries who inspire followers to transcend their own self-interest to obtain greater achievement for the organization. These managers empower employees to break out of paradigms and think of new ways of doing things. Transformational leadership employs management by exception and the leader only takes the initiative when a problem arises that personnel can’t resolve.
I’ve discussed four leadership theories developed over the years. The strength of the theory is relative and is determined ultimately by the situation to which it is applied. The bottom line is each theory has merit and there is no best way to measure a leader or a leader’s effectiveness.
