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

[Even if established procedures exist for replacing leaders,] they are relatively harmless to the entrenched leaders (because functionless) so long as the ranks fear the consequences of using them

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.

An organization is a group of living human beings. The formal or official design for living never completely accounts for what the participants do. It is always supplemented by what is called the “informal structure,” which arises as the individual brings into play his own personality, his special problems and interests. Formal relations co-ordinate roles or specialized activities, not persons.
