What is Bereaucracy?*
 

A bureaucracy is an organization, whether publicly or privately owned, made up of several policymaking departments or units. People who work in bureaucracies are informally known as bureaucrats.

While the hierarchical administrative structure of many governments is perhaps the most common example of a bureaucracy, the term can also describe the administrative structure of private-sector businesses or other non-governmental organizations, such as colleges and hospitals.
