Fiedler's Contingency Model is a leadership theory developed by Fred Fiedler that suggests a leader's effectiveness depends on the situation and their leadership style. Fiedler identified two main styles: task-oriented and relationship-oriented. Task-oriented leaders focus on completing tasks, while relationship-oriented leaders prioritize team dynamics and morale. The model emphasizes that no single leadership style is best; instead, the effectiveness of a leader varies based on factors like the leader's control over the situation and the nature of the task. By assessing these elements, organizations can better match leaders to situations for improved performance and team success.
