John Zachman on Enterprise Architecture: Profession vs. Trade

John Zachman talks about Enterprise Architecture and whether it is a profession or a trade. Throughout history, what determines a profession in a particular industry, is the ability to do diagnosis- otherwise that discipline is just a trade based on labor and practitioner experience. The Professional Service Cycle states that an ontology (the Zachman Framework), allows practitioners in a discipline to repeat and predict, giving them the ability to diagnose and provide solutions. This is the difference between a Doctor and an X-ray technician. The Zachman Framework - Enterprise Ontology gives EA professionals the ability to diagnose and become "Enterprise Doctors" as opposed to "Enterprise Technicians."
