Situational leadership is a leadership model created by Ken Blanchard and Paul Hersey that involves assessing the development level of followers and adapting one's leadership style accordingly. The model analyzes the needs of each situation and selects the most appropriate leadership style. It has proven popular with managers because it is simple to understand and works in most environments. Effective leaders are able to move between different leadership styles based on whether followers require directing, coaching, supporting, or delegating.
