SLT is developed by Dr. Paul Hersery and Ken Blanchard. They believe there is no single universal effective leadership method that exists, as any form of leadership style or method can be effective under certain condition. The most effective leadership style is a complex of leadership method, and the successful leader “must tailor their approach to the maturity of the followers and the situation, or details and environment, of the assignment” (Campbell, 2015).
