From EA 1.0 to EA 5.0: An EACOE Perspective on the Evolution of Enterprise Architecture

Enterprise Architecture (EA) has evolved through several distinct eras, reflecting shifts in technology, economics, and the nature of competition. Much of the mainstream EA discourse remains anchored in Industrial Age and early Internet Age thinking, emphasizing cost justification, technology platforms, and documentation‑centric practices. In contrast, the Enterprise Architecture Center Of Excellence (EACOE) has articulated a progression that foregrounds information as the core asset, continuous architecture as a discipline, and a practitioner‑based, competency‑driven model in what it terms Enterprise Architecture 5.0.
