Enterprise Architecture and the Business of IT

Blog: Form Follows Function

Turning Gears Animation

I’ve been following Tom Graves and his Tetradian blog for quite a while. His view of Enterprise Architecture (EA), namely that it is about the architecture of the enterprise and not just the enterprise’s IT systems, is one I find compelling. With some encouragement on Tom’s part, I’ve begun touching on the topic of EA, although in a limited manner. When it comes to enterprise architecture, particularly according to Tom’s definition, I consider myself more of a student than anything else. I design software systems and systems of systems, not the enterprises that make use of them.

However…

I’m finding myself drawn to the topic more and more these days. I’m finding it more and more relevant to my work. The fractal nature of social systems using software systems is a major theme of the category “Organizations as Systems” on this site. If the parts fit poorly, then the operation of the system they comprise will be impeded. A good way to ensure the parts fit poorly is to fail to understand the context in which they will inhabit. So while I may not be designing the social system which my systems fit into, an understanding of how that system functions is invaluable, as is an understanding of how my social system (IT) interacts with my client’s social system (the rest of the business) to further the aims of the enterprise.

Tom’s latest post, “Engaging stakeholders in health-care IT”, is an excellent example of how not to do things. In the post, Tom discuss attending a conference on IT in healthcare where the players had no real knowledge about healthcare. They couldn’t even identify the British Medical Journal or the Journal of the American Medical Association, much less have an idea about what issues might be found in the pages of those publications. They didn’t feel that was a problem:

Well, they didn’t quite laugh at me to my face about that, but in effect it was pretty close – a scornful dismissal, at best. In other words, about the literally life-and-death field for which they’d now proclaimed themselves to be the new standard-bearers, they were not only clueless, but consciously clueless, even intentionally clueless – and seemingly proud of it, as well. Ouch… At that point the Tarot character of ‘The Fool’ kinda came to mind – too self-absorbed to notice that he’s walking straight over a cliff

While I recently advocated embracing ignorance, it was in the context of avoiding assumption. The architect will know less about the business than a subject matter expert who will most likely know less than the end user on the pointy end of the spear. The idea is not to remain ignorant of the domain, but to avoid relying on our own understanding and seek better sources of information. It’s unreasonable to think we can design a solution that’s fit for purpose without an understanding of the architecture of the problem, and make no mistake, providing solutions that are fit for purpose is the business of IT.
