Enterprise Architecture is probably one of, if not he the most, misunderstood terms in the business and IT world today. Most people have a definition for it - The problem is, a lot of those definitions are either incomplete or just plain wrong. I know because I used to be one of those people. It has become clear to me that Enterprise Architecture is not complicated, is not difficult, is not expensive. Of course there are elements out there who would prefer boards and organisations to think that it is complicated, is difficult and therefore is expensive. That is not to say that Enterprise Architecture does not have its issues problems and risks. However, so long as the key tenet’s are understood and the issues, problems and risks are managed, any organisation can instigate and reap the benefits of Enterprise Architecture.
This illustrates the basic structure that all models will follow. Each piece of information in a model can exist at different times – yesterday, today, tomorrow, etc. Each piece of information in a model can be grouped into one or more domains – business, technology, etc. Each piece of information in a model can exist at different levels of abstraction – where transistion from one level to another requires a transformation of some kind. NOTE - Abstraction is not composition/decomposition. Composition/decomposition. Can exist as a fourth dimension anywhere in the model.
