Architecture Is Not a New Idea

The ideas about Architecture have been around for a long time. In the old days we used to call this kind of thing “Enterprise Analysis." The whole concept of Enterprise Analysis was, or is, you try to understand the Enterprise first, before you try to overlay infrastructure kinds of things against it.

The problem with infrastructure kinds of things is, it takes a long time to create it... and it costs a lot of money... and after you get it created... it is hard to change it. So the best thing to do is to understand what you are going to do with it before you take the time and sink the money into creating it. That is not a new idea... I think it came from Julius Caesar... or maybe it was Adam... in any case, it came from somebody a long time ago and I did not invent it. Even in the context of Enterprises, it is not a new idea. I probably spent more than 40 years of my professional life focused around these kinds of ideas in Enterprises.

It is not a revolution in technology, machinery, techniques, software or speed. It is a revolution in CONCEPTS.”

Roger Greer, who at the time was the Dean of the School of Library and Information Management at the University of California (USC), made some observations about a Professionals in contrast with Labor. He defined the Professional Service Cycle as depicted in Figure 1.
