Institutionalization is a process. It is something that happens to an organization over time, reflecting the organization’s own distinctive history, … - Philip Selznick

The formal administrative design can never adequately or fully reflect the concrete organization to which it refers, for the obvious reason that no abstract plan or pattern can—or may, if it is to be useful—exhaustively describe an empirical totality. At the same time, that which is not included in the abstract design (as reflected, for example, in a a staff and-line organization chart) is vitally relevant to the maintenance and development of the formal system itself.

The most important thing about organizations is that, though they are tools, each nevertheless has a life of its own.

There seems to be little doubt that the factor of sheer size is a very important element in concrete bureaucratic structures. However, because of the patterns exhibited in the behavior of agents in small organized groups and because of the implications for greater generality, the formulation used here does not make the factor of size crucial for the existence of bureaucratic behavior patterns.
