Organizational scientist Karl Weick noticed that some organizations can be mechanistic (coupled) and organic (loose) at the same time. Loosely coupled organizations are under influence of forces or conditions that hold them together, but at the same time they are acting with the high degree of independence.

In software engineering, loose coupling has similar notion to organizational theory. A loosely coupled system usually consists of a framework or architecture linking together otherwise independent components. The components are usually highly cohesive and have well defined responsibilities....
