Jack’s view of leadership is multi-level, multidimensional, and social-psychological, i.e., he considers leadership not simply an individual collection of traits, nor a series of interpersonal transactions, but Leadership is then a social and psychological process that is fundamentally exercised in the small group. Organizational behaviour, consequently, is an expression of conscious cognitive and largely unconscious emotional group and intergroup dynamics. The primary task of leadership development, then, is then to provide the opportunity for individuals to develop their capacity to exercise leadership responsibly.
