The contingency theory, proposed by Fred Fiedler in the mid-1960s, is a theory of leadership.

The main assumption of this theory is that the effectiveness of leadership depends on matching the leadership style to the situation. It states that there is no single leadership style that fits all situations. Therefore, to make a leadership style effective, it should be adjusted according to the situation. As the name “contingency model” indicates, Fiedler believed that leadership effectiveness is contingent upon the situation.

Fiedler identified two primary leadership styles: task-oriented and relationship-oriented. To assess these leadership styles, he developed a scale called the Least-Preferred Co-worker scale (LPC scale). This scale asks the respondent to rate the person they have least enjoyed working with. It can be any person that the respondent has worked with in an organization. The scale simply requires the respondent to rate the person with whom they have had the least favorable working experience. A high score on this scale (LPC) indicates that the respondent is a relationship-oriented leader. In contrast, a low score on this scale (LPC) suggests that the respondent is a task-oriented leader.

The interpretation of LPC scores is based on underlying leader attitudes. Task-oriented leaders prioritize achievement and high performance standards, often expressing lower satisfaction with colleagues who do not meet these expectations. Since they prefer high performance, they seek perfection and, thus, are not easily satisfied with the work of others. As a lower score on the LPC scale shows the respondent’s lesser satisfaction with the person they have worked with, this indicates that the respondent is likely to be a task-oriented leader. In other words, because a task-oriented leader prefers high performance, they will rate the co-worker lower due to a more critical evaluation.

On the other hand, relationship-oriented leaders place greater emphasis on maintaining harmonious interpersonal relationships. They believe more in maintaining good relationships with other workers to achieve goals and, thus, generally do not view low-performing workers negatively because they want to avoid conflicts and sustain positive relationships. They are generally more tolerant of lower performance levels in order to preserve positive working relationships. Due to this, they may feel relatively satisfied with other workers even if their performance is relatively low. Since a high score on the LPC scale reflects higher satisfaction with the person they have worked with, this indicates that the respondent is likely to be a relationship-oriented leader.

Fiedler initially proposed that task-oriented leaders were inherently more effective than relationship-oriented leaders, based on the assumption that they possess the personality traits required for getting the job done and are therefore better suited for achieving organizational goals. Initially, Fiedler did not take into account situational factors when assessing leadership outcomes. However, he later realized that it is not only the personality of a leader that determines effectiveness, but also the situational factors.

He concluded that effective leadership depends not only on the leader’s personality traits but also on situational favorability. Situational favorability refers to the extent to which a given situation is conducive to the effectiveness of a particular leadership style. If the situation supports the leadership style, the leader is likely to perform better. However, if the situation is not favorable for a specific leadership type, the leadership style should be adjusted to the situation to improve performance.

Fiedler believed that the effectiveness of leadership is influenced by the degree of situational favorability. The situation can be extremely favorable, moderately favorable, or extremely unfavorable. However, it is essential to first understand what the term “situation” means in Fiedler’s theory. Here, the situation is determined by three key variables: leader–member relations, position power, and task structure. Together, these factors shape the extent to which a situation supports effective leadership.

1. Leader–Member Relations
   This factor refers to the level of trust, respect, and confidence that subordinates have in their leader. Strong, positive relationships facilitate cooperation and commitment, making it easier for the leader to achieve organizational objectives. A favorable leader–member relationship fosters a supportive work environment characterized by mutual understanding and minimal conflict.
2. Position Power
   Position power denotes the level of formal authority and control a leader has in relation to subordinates. It reflects the extent to which a leader can grant rewards or impose punishments. Greater position power enhances a leader’s ability to influence subordinates and enforce decisions, thereby contributing to improved group performance and effectiveness.
3. Task Structure
   Task structure refers to the degree to which job tasks are clearly defined, organized, and standardized. It encompasses the clarity of roles, procedures, and expected outcomes, as well as the coordination required among team members. In simple terms, it refers to who will perform which task and when the task will be performed. It also includes how tasks will be completed collaboratively by workers. Highly structured tasks, supported by well-defined rules and policies, reduce ambiguity and facilitate efficient performance. In contrast, unstructured tasks with unclear guidelines may create uncertainty and hinder productivity.

As noted above, Fred Fiedler initially proposed that task-oriented leadership is generally more effective than relationship-oriented leadership. However, he later realized that the task-oriented leadership style may not be productive in all situations. Therefore, he concluded that leadership effectiveness is contingent upon situational conditions.

Specifically, task-oriented leadership tends to be most effective in situations that are either highly favorable or highly unfavorable, where clear direction and strong control are required. Conversely, in moderately favorable situations, relationship-oriented leadership is more effective, as it emphasizes interpersonal relationships, collaboration, and team cohesion. Thus, the leadership style should generally be adjusted to the situation to work effectively.
