Bureaucracy is a formal organization with clear hierarchies, divisions of labor, and emphasis on written rules and communication. It has several key characteristics: a hierarchy of authority with each level responsible for those below; specialized divisions of labor where each member has a specific task; extensive written rules and procedures to cover all situations; record keeping through written memos and reports; and impersonality where the office is more important than the individual and workers owe allegiance to the organization rather than people. The goal is to achieve objectives through efficiency with each person serving as a replaceable unit.
