I’d like to make the case why business architects should operate outside of enterprise architecture (EA).
First, business architects are “big thinkers” and more business savvy than their EA counterparts. Their cultures clash. No matter how much EAs cast themselves as strategic thinkers, trusted advisors, or business partners there still seems a stigma that EA is only all about IT. This stigma stuck for decades and may help explain why IT-oriented EAs attracted only their kind. Meanwhile, recent converts to business architecture possess a distinct left- and right-brained aptitude for stating holistic viewpoints that are rigorous, well-understood, and fact-based. Some of them are ex-product managers, ex-business analysts, ex-sales, ex-entrepreneur, or simply ex-EAs or ex-IT pros who recently earned their MBAs and a light bulb went on, so to speak.
