Enterprise architecture (EA) has primarily a business focus, but it involves the kind of systems thinking typically associated with information technology (IT). Any one of its component architectures could theoretically drive a business transformation. The example of process architecture is chosen because of its implications for other architectural domains; because of the link between customer-centricity and process-centricity; and because inherited attitudes to process desperately need overhaul. An imagined diagnostic in a financial services company provides context. The diagnostic recommends a holistic alternative to current approaches to process. It articulates an explicit logical meta-model from which it draws out a number of key concepts implementable as generic physical constructs. The resulting process architecture can drive radical business transformation given the right program management, governance, and, above all, sponsorship.
