One standard to rule them all
from strategy to execution.

Keystone EA™ is the Enterprise Architecture standard that simplifies strategy to execution. A layered metamodel to build a strong foundation for insight. A rule-governed relationship system to simplify work and reduce errors. Six viewpoints to gain value from data.

What it is

A single connected model of the enterprise. Intuitive. Effective. Simple.

How many times has your architecture team spent months learning a heavy standard instead of getting the work done? Or have you spent months agreeing over the small details of a loose standard?

Keystone EA™ balances rigor with agility, enough to keep a live repository both consistent, and light enough to use day-to-day.

This standard describes the organisation as one model tying together strategy, governance, business, data, applications, and technology. Each element has a defined type, and every relationship is governed by an explicit rule.

From a board-level driver down to a database engine, everything traces through the same fabric.

Keystone EA's power lies in three parts. Start with a metamodel, communicate with a viewpoint library, and execute with a proven implementation methodology.

The layered model

Seven layers, top to bottom, intent to delivery.

Keystone EA™ stacks the enterprise into seven layers. Upper layers express intent; lower layers deliver it. Every object type lives in exactly one layer.

Design principles

Design that cuts through the noise.

Lean by design

Hundreds of object types simplified to 19 to create a dependable model of the enterprise that is easy to maintain and read.

Link any object, with rules

Leverage flexibility by linking any objects without worrying about governance. The rule matrix for relationships keeps your model consistent with room for innovation.

Viewpoint-driven

Don't get overwhelmed by a mammoth model. Impactful Viewpoints filter your model into key object types, whether that's strategy, technology, capability, or governance.

AI-assisted delivery

The methodology assumes a live repository accelerated by AI. Fill in the gaps, generate content quickly, or automate impact analysis.

Consistent Visibility

With Realization relationships, visualise the common thread from a strategic driver, through capabilities and applications, down to the infrastructure that ultimately delivers it.

Governance, sorted. Always

The model is built on principles and standards, guaranteeing compliance as you work. Leverage a technology reference model that is wired into governance.
