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.

Running an organisation... generates problems, which have no necessary (and often an opposed) relationship to the professed or "original" goals of the organization. The day-to-day behaviour of the group becomes centered around specific problems and proximate goals, which have primarily an internal relevance. Then, since these activities come to consume an increasing proportion of the time and thoughts of participants, they are-from the point of view of actual behaviour – substituted for the professed goal.

Organisations are technical instruments; designed as means to definite goals... they are expendable. Institutions... may be partly engineered, but they have also a “natural” dimension. They are the products of interaction and adaptation; they become the receptacles of group idealism; they are less readily expendable.
