Heterarchy is  formal structure, which usually represented by a diagram of connected nodes, without any single permanent uppermost node. It is form of management or rule in which any unit can govern or be governed by others, depending on circumstances, and, hence, no one unit dominates the rest. It may parallel to a hierarchy, subsumed to a hierarchy, or it may contain hierarchies; the two kinds of structure are not mutually exclusive. This is a state wherein any pair of items is likely to be related in two or more differing ways.
