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.

Institutionalization is a process. It is something that happens to an organization over time, reflecting the organization’s own distinctive history, the people who have been in it, the groups it embodies and the vested interests they have created, and the way it has adapted to its environment.
