For years I’ve been fascinated by the usage of EA as a means to document and structure all aspects of an enterprise. There are many good sources of information out there today that will show you how to do that. But what about reasoning about the enterprise, what models exists to do that. I’ve put together a presentation (see below) which may awake some to the issue of modeling just enough of the enterprise for documentation. Perhaps we can move our EA focus towards using models for reasoning and strategizing. This would enable EA to act as a guide towards understanding the emerging strategy within the organization and its value network.
