Considering the forum in which this article is published, I think it is safe to say that anyone reading it already knows the value of Business Architecture. I hope we also share the opinion that the IT Architecture is secondary to the Business Architecture: the business is the driver, not IT.
That is nice theory, but it hasn’t been reality for quite some time. New technology trends emerge, people with an eye for technology see the benefits, and they sell the idea of implementing the new technology based on those benefits.
