Three Schools of Thought on Enterprise Architecture

Three schools of thought on enterprise architecture exist, each with its own belief system (definitions, concerns, assumptions, and limitations). A novel taxonomy of these schools creates a starting point for resolving terminological challenges to help establish enterprise architecture as a discipline.

If organisations are to survive the turbulence of today’s markets, they must learn to adapt and innovate. A survey by the Gartner and Forrester technology market consulting firms shows that current enterprise architecture practices, which are mostly based on the enterprise IT architecture school of thought, aren’t doing very well—they lack acceptance and are perceived as organisationally inconsiderate. It is recommended that the enterprises should have to move to more holistic ways of thinking if they wish to survive and flourish.
