One of the very early points that was made is that the behavior you reinforce in an organization is the behavior you get, hence the premise for the entire class, organizational behavior, or in other words why do people do the things that they do in organizations.
The organizational culture addresses the value system of the organization, what gets rewarded, how people interact, and the diversity of the organization itself. It also points to the answers to the following questions: how do you succeed? And do you fit in?
We learned the PIE acronym for success in an organization:
P is for performance
I is for image (and is that image consistent with the culture)
E is for exposure and visibility
