Methodology
From foundation to transformation, in five phases
KeystoneEA™ is our optional, output-based methodology. A clear, proven path that takes your EA practice from getting started to delivering strategic value.
Use it as a guide — or bring your own. The platform adapts either way.
Phase 01
Establish
Get the foundations in place — catalogs, metadata, and a model your team can trust.
Phase 02
Structure
Add governance and validate the model so the practice runs the same way every time.
Phase 03
Activate
Bring it live — applications, capabilities, and the technology reference model in active use.
Phase 04
Optimize
Deepen coverage with integration, data architecture, and future-state planning.
Phase 05
Transform
EA becomes strategic — embedded in business planning, powered by AI, continuously improving.
The fastest path to EA ROI. Our proven methodology gets you delivering richer, more valuable architecture from day one — and compounds that value at every stage of maturity.
Metamodel
A structured language for your architecture
Every object in KeystoneEA™ belongs to one of seven layers — each with a precise meaning. Together they give your architecture a consistent, shared vocabulary across every team and viewpoint.
Objects connect through six relationship types — Composition, Connection, CRUD, Realization, Flow, and Supporting — giving you a precise, consistent way to express how your architecture fits together.
