Enterprise Architecture (EA) is defined not as diagrams or IT systems, but as the strategic discipline of designing how an organization creates coherent value through structure, relationships, and intentional evolution. The post distinguishes between EA (describing organizational structure and logic) and Enterprise Architecture Management (ensuring that structure actively influences decisions and investments). Key points include: terminology alignment is foundational before solutions are discussed; EA spans the full enterprise — business model, governance, capabilities, information flows, and technology; architecture models (capability maps, roadmaps) are instruments, not the architecture itself; and EA success is often invisible — when it works, transformation feels coherent; when it fails, fragmentation and contradictions become visible.
