Carter McNamara called organizational culture the personality of your organization. By itself, it may be difficult to define but everyone can sense it. Not only those who are part of the organization but even people viewing it from the outside. For example, I have found waiting in the reception highly educative and informative. I am convinced that a few minutes of waiting at the reception, tells me more about that organization than the formal presentation I am given by their executives when we meet shortly after.
The spring in the steps of employees as they go about their work, the smiles , the cheerful banter tells you something about the organization. On the contrary in some receptions, I also see grouchy faces, tense and ready to snap; people dragging themselves from place to place and an overall image of sloth and disinterest.
