Explanation:

Situational Leadership Theory, or the Situational Leadership Model, is a model created by Paul Hersey and Ken Blanchard, developed while working on Management of Organizational Behavior. The theory was first introduced in 1969 as "life cycle theory of leadership".During the mid-1970s, life cycle theory of leadership was renamed "Situational Leadership Theory.

Situational Leadership emerged as one of a related group of two-factor theories of leadership, many of which originated in research done at Ohio State University in the 1960s. These two-factor theories hold that possibilities in leadership style are composed of combinations of two main variables: task behavior and relationship behavior. Various terms are used to describe these two concepts, such as initiating structure or direction for task behavior and consideration or socioemotional support for relationship behavior.
