Dr. Leon A. Kappelman started talking about enterprise architecture. He started by referring to the financial industry in the US and the fact that their models did not see interactions between the different organizations and the effects the failure of one might have on the others.

He mentioned that in 2007 he started working with a group of people on Enterprise Architecture, and they collected articles and created a book called “The SIM Guide to Enterprise Architecture”. The books is not available just yet, but should be available shortly.

He defines Architecture as the set of descriptive representations about an object. Architecture is modeling. It is about having a way to communicate with all the people involved in a project.

Models are imperfect by nature. A map is not the actual highway, it is a representation of reality. But the point is that it must be useful, do we agree on the meaning of the symbols in the model.

So why bother about Enterprise Architecture? If you can’t see it, you can’t manage it, especially if it’s big and needs to change.

Enterprise Architecture is what you need to know about an enterprise to know the enterprise. EA is modeling the enterprise. It is about creating a language to communicate with people.

A very interesting presentation overall a lot of it referring to John Zachman’s (who is presenting next) model.
