Modern organizations have other characteristics as well. Samuel Huntington lists four criteria for measuring the degree of development of the institutions that make up the state: adaptability-rigidity, complexitysimplicity, autonomy-subordination, and coherence-disunity.16 That is, the more adaptable, complex, autonomous, and coherent an institution is, the more developed it will be. An adaptable organization can evaluate a changing external environment and modify its own internal procedures in response. Adaptable institutions are the ones that survive, since environments always change. The English system of Common Law, in which law is constantly being reinterpreted and extended by judges in response to new circumstances, is one prototype of an adaptable institution. Developed institutions are more complex because they are subject to a greater division of labor and specialization. In a chiefdom or early state, the ruler may be simultaneously military general, chief priest, tax collector, and supreme court justice. In a highly developed state, all of these functions are performed by separate organizations with specific missions and a high degree of technical capacity to undertake them. During the Han Dynasty, the Chinese bureaucracy ramified into countless specialized agencies and departments at national, prefectural, and local levels. While much less complex than a modern government, it nonetheless represented an enormous shift away from earlier governments that were run as simple extensions of the imperial household.
