Enterprise Architecture
on a Page
An interactive navigator for Svyatoslav Kotusev's EA framework — four interconnected reference models covering the practice, function, maturity and artifacts of enterprise architecture.
EA Practice on a Page
Three EA Processes
Strategic Planning, Technology Optimisation, and Initiative Delivery — their goals, structures, inputs, outputs and artifact lifecycles.
EA Function on a Page
Architecture Function
Architecture tiers, governance bodies and procedures, architect roles, domains, and the typical ratio of architects to IT staff.
EA Maturity on a Page
Four Maturity Stages
From no architectural planning to full enterprise-wide alignment — each stage's function, artifacts, processes, benefits and challenges.
EA Artifacts on a Page
28 EA Artifacts
All artifact families — Considerations, Visions, Outlines, Standards, Landscapes and Designs — with format, audience and practical notes.

EA Practice on a Page
An aggregated view of the three processes constituting an EA practice, their interrelationships and properties.
EA Maturity on a Page
An aggregated view of the maturity of an EA practice with its different stages and their essential properties.
This model is purely descriptive — it reflects typical historical paths of most organisations, but is not prescriptive of a mandatory sequence. In large organisations, different parts of their EA practices may be at different stages across their different divisions.
EA Function on a Page
An aggregated view of architecture functions in organisations with their positions and governance bodies.
