Using Hungarian Cube to demonstrate enterprise architecture
I started the show holding the cube very close to my eyes. What I'm doing right now is technology architecture, I said. I see just one side of the cube, but I can see in detailed what exist on each surface of each rectangle of this side. That's what you are doing now, Having the cube so close to your eyes you see and capture every aspect of the cube surface (or technology architecture). Although this is an important work this is not EA.
In order to do EA we MUST take the cube away from our eyes, so we can see three sides of the cube and the relations between them. Actually we need to roll the cube to see all 4 elements of the cube. When we take the cube away from our eyes we can see the holistic view of the enterprise, which is enterprise architecture. When we take the cube away we can't see anymore all the details on the cube sides surface, therefore we can't capture low level details of the cube surfaces (or different enterprise architecture domains). As anything in life there are compromises, we can see the holistic view of the enterprise but we can’t do out work using the same level of granularity as we've done while doing technology architecture.
