A bureaucracy is a special type of functional organization that is characterized by high formalization, a well-defined hierarchy, and extensive training of personnel who function by following written rules.

A bureaucracy has highly routine operating tasks and very formalized rules and regulations. Tasks are grouped into functional departments, often with centralized authority. Decision making follows the chain of command, and an elaborate administrative structure with sharp distinction between line and staff is often made.

The functional organization structure is hierarchical, complex, and elaborate.

One of the primary characteristic is the adherence to rules.
