In an organizational context, the following terms are often used related to hierarchies: These terms are easiest to understand when a hierarchy is diagrammed (see below). Hierarchies have their own special vocabulary. See also: Glossary of graph theory, Taxonomy (general), and Structure Organizational forms exist that are both alternative and complementary to hierarchy. This is akin to two co-workers or colleagues each reports to a common superior, but they have the same relative amount of authority. All parts of the hierarchy that are not linked vertically to one another nevertheless can be "horizontally" linked through a path by traveling up the hierarchy to find a common direct or indirect superior, and then down again. Hierarchical links can extend "vertically" upwards or downwards via multiple links in the same direction, following a path. The only direct links in a hierarchy, insofar as they are hierarchical, are to one's immediate superior or to one of one's subordinates, although a system that is largely hierarchical can also incorporate alternative hierarchies. Hierarchy is an important concept in a wide variety of fields, such as architecture, philosophy, design, mathematics, computer science, organizational theory, systems theory, systematic biology, and the social sciences (especially political philosophy).Ī hierarchy can link entities either directly or indirectly, and either vertically or diagonally. For other uses, see Subordination.Ī hierarchy (from Greek: ἱεραρχία, hierarkhia, 'rule of a high priest', from hierarkhes, 'president of sacred rites') is an arrangement of items (objects, names, values, categories, etc.) that are represented as being "above", "below", or "at the same level as" one another.
