Enterprise Architecture's Identity Crisis

This chapter outlines the rational foundations of the enterprise architecture discipline to date and describes ways and situations in which the traditional approaches of enterprise architecture fail to account for a number of contemporary market and economic situations and organizational behaviors. It characterizes new methods and approaches loosely based on systems thinking, with examples from the Australian e-government experience, and argues that the discipline must re-invent itself to incorporate a post-rational perspective to stay relevant. The chapter concludes with narratives of how the new enterprise architecture must engage with business to stay relevant over the next decade and beyond.
