"Since the concentric organization chart has neither top nor bottom, the interpretations of the relationships existing within the organization are not dependent upon the position of the diagram which represents them. Any organization chart is designed to present certain facts about a given organization at given time. These facts or relationships do not depend on viewing the organization from any particular angle or any specific position, which is also the case for the concentric organization chart. However, with the traditional organization chart, the relationships which it intends to portray can be interpreted properly only when the chart is presented to the viewer in a certain position, that is, with the top at the top and the bottom at the bottom. Should this not be done, the organization should be upside down Should this not be done, the organization would be upside down, with relationships existing inversely to the facts of the organizational structure."
