In ordinary usage, “bureaucracy” refers to a complex, specialized organization composed of non-elected, highly trained professional administrators and clerks hired on a full-time basis to perform administrative services and tasks. Bureaucratic organizations are broken up into specialized departments or ministries, to each of which is assigned responsibility for pursuing a limited number of the government's many official goals and policies those falling within a single relatively narrow functional domain. The departments or ministries are subdivided into divisions that are each assigned even more specialized responsibilities for accomplishing various portions or aspects of the department's overall tasks and these divisions are in turn composed of multiple agencies or bureaus with even more minutely specialized functions. Bureaucratic organizations always rely heavily on the principle of hierarchy and rank, which requires a clear, unambiguous chain of command through which “higher” officials supervise the “lower” officials, who of course supervise their own subordinate administrators within the various subdivisions and sub-subdivisions of the organization.
Bureaucratic organizations are typically characterized by great attention to the precise and stable delineation of authority or jurisdiction among the various subdivisions and among the officials who comprise them, which is done mainly by requiring the organization's employees to operate strictly according to fixed procedures and detailed rules designed to routinize nearly all decision-making. Some of the most important of these rules and procedures may be specified in laws or decrees enacted by the higher “political” authorities that are empowered to set the official goals and general policies for the organization, but upper-level (and even medium-level) bureaucrats typically are delegated considerable discretionary powers for elaborating their own detailed
