In order the discuss and distinguish the five distinct organizational configurations, Mintzberg first discusses the five component parts which make up the whole organization: strategic apex, operating core, technostructure, support staff, and middle line. He then continues with describing how each of these elements cluster into the five configurations. Each of these five configurations (simple structure, machine bureaucracy, divisional form, adhocracy) are discussed in detail, with both their strengths and weaknesses. So how do we need to use these configurations? "... this set of five configurations can serve as an effective tool in diagnosing the porblems of organizational design, especially those of the fit among component parts." Mintzberg uses four basic forms of misfit to show how managers should use it as a diagnostic tool. He emphasizes that especially fit remains an important characteristic. There are excellent graphs, tables, and a great appendix explaining the organizational configurations and component parts. The author concludes that "the point is not really which configuration you have; it is that you achieve configuration."

Yes, this is one of the best articles I have read. It provides a great introduction/framework into organizational structures and design. Mintzberg does not want us to see his introduction as a framework. But I disagree. This article is thorough enough to use as a framework, keeping in mind that larger organizations (can) consist of a mixture of the discussed configurations. For people interested in a further discussion of organizational structures I refer to Henry Mintzberg's 1978-book "The Structuring of Organizations". This article should be compulsory reading for managers and MBA-students. The author uses simple business US-English.

That's the best tool to use when you want to see your company focused in the structure analysis, to take the actions to align the model. This article is old, but is actual too, then you want to know it.
