The concept of bureaucracy is the original meaning of “officialdom government”. The concept was designed by German sociologist Max Weber as a concept of professional and effective management of large organizations based on clear and formalized rules, and on disinterested, and professional work of quality officials. Part of the concept is also a clear hierarchy and specialization of functions. Weber understands the concept as neutral and perceives it as a kind of power (domination), as in a rational authority.
The term is also sometimes used pejoratively for “rigid and inflexible management system.”
Note: In Weber’s time the concept of “bureaucracy” was a professional term and completely lacked pejorative tinge, which today it usually has in colloquial language.
