This is an abridged version of the EA Forum presentation2Copyright © Real IRM Solutions (Pty) Ltd 2016“Interest in business architecture is growing dramatically. During the past two years both IT and business leaders have joined the discussion about the need for a well -defined business architecture. Though there is a great deal of discussion, there is little consensus about what business architecture is, how it should be pursued, and what value it delivers. Business architects in IT as well as in the business have started developing business -unit-wide and enterprise- wide business architectures, learning as they go. Their ultimate goals are to improve business decision- making and facilitate better alignment between IT and the business units it supports. Architecture teams that want to play a leading role in business architecture development must start soon or be left behind.” Jeff Scott, Forrester Research, 2008Approaches to Business Architecture3Copyright © Real IRM Solutions (Pty) Ltd 2016The Open Groups view (O -BA Part I) … “The formalised description of how an organisation uses its essential competencies for realizing its strategic intent and objectives.”What is Business Architecture?4Copyright © Real IRM Solutions (Pty) Ltd 2016Business Architecture Working Groups updated …. “A Business Architecture is a formal blueprint of governance structures, business semantics and value streams across the extended enterprise.
