While there has been a sequential development in the theories elements from an earlier theory will appear again in the work of a more recent theory.
These four groups of theories share some common qualities and are viewed as variations of the classical model of leadership. Doyle, M. E. and Smith, M. K. (2001) describe the classical view of leadership as sharing the following elements where leaders (i) tend to be identified by membership of the hierarchy (ii) become the people to whom others turn when they don't know what to do, or won't work things out for ourselves (iii) give direction and have vision.
