After some time thinking about my last post about EA being dead, I decided to resurrect it and marry it up with three other diciplines that I have been working in for the last 10 years; that being Strategic Management, Business Process Management and (now) Service Oriented Architecture. If you’re going to use the word “enterprise” in the context of architecture, then doesn’t it make sense to include the WHOLE enterprise?
So, the result of my thinking is shown below - I’m calling it EA v2.0. When you look at the diagram, the one thing to pay attention to is the relationships between the layers of the model, and not so much what’s in each layer. The fact is that fairly mature methodologies exist for every layer. This model is my attempt to build better understanding about the linkages BETWEEN the layers. In other words, there are a lot of models out there for conducting strategic planning, business process modeling, workflow management, and technology archtiecture; however, I have yet to find anything that explains in simple terms how all this crap ties together in a way that organization executives can understand.
So, take a look at my EA v2.0 reference model below and tell me what you think….r/Chuck
