A deeper understanding of cultural issues in organizations is necessary not only to decipher what goes on in them but, even more important, to identify what may be the priority issues for leaders and leadership. Organizational cultures are created by leaders, and one of the most decisive functions of leadership may well be the creation, the management, and--if and when that may become necessary--the destruction of culture. Culture and leadership, when one examines them closely, are two sides of the same coin, and neither can really be understood by itself. In fact, there is a possibility--underemphasized in leadership research--that the only thing of real importance that leaders do is to create and manage culture and that the unique talent of leaders is their ability to work with culture.
