Cultures surround us all. Cultures are deep seated, pervasive and complex. Yet, according to Edgard Schein, "Organizational learning, development, and planned change cannot be understood without considering culture as the primary source of resistance to change." And "The bottom line for leaders is that if they do not become conscious of the cultures in which they are embedded, those cultures will manage them. Cultural understanding is desirable for all of us, but it is essential to leaders if they are to lead". With the Three Levels of Culture, Edgard Schein offered an important contribution to defining what organizational culture actually is. In his classic book: Organizational Culture and Leadership" (1992) Schein defines the culture of a group as: "A pattern of shared basic assumptions that the group learned as it solved its problems of external adaptation and internal integration, that has worked well enough to be considered valid and, therefore, to be taught to new members as the correct way to perceive, think, and feel in relation to those problems". In a more recent publication Schein defines organizational culture as "the basic tacit assumptions about how the world is and ought to be that a group of people share and that determines their perceptions, thoughts, feelings, and, their overt behavior" (Schein, 1996) Schein (1992) acknowledges that, even with rigorous study, we can only make statements about elements of culture, not culture in its entirety. The approach which Schein recommends for inquiring about culture is an iterative, clinical approach, similar to a therapeutic relationship between a psychologist and a patient. Schein?s disciplined approach to culture stands in contrast to the way in which culture is referred to in some of the popular management magazines.
