Traditional Enterprise Architecture frameworks like TOGAF divide work into four domains (business, data, application, technology), creating silos that fragment responsibility and limit holistic thinking. A more effective approach views architecture through organizational scope levels—Enterprise, Segment, and Solution Architects—where each role maintains an organization-wide perspective at different granularities. The Enterprise Architecture Implementation Wheel offers a modern alternative that centers architecture as a guiding force through continuous cycles of documenting, defining, executing, and controlling, rather than partitioning by domain. This shift enables architects to contribute across all concerns while maintaining strategic coherence and alignment.
