Linked.Archi EA-as-a-Service Extension
Extension ontology for modeling the EA function as an internal management consultancy. Provides vocabulary for EA service catalogs, service engagements, stakeholder satisfaction, EA capability portfolios, and maturity assessment. Addresses the Gartner 2025 prediction that by 2028, half of EA teams will rebrand themselves to emphasize their strategic role as business partners. Formalizes the shift from "architecture practice" to "architecture services" by making service offerings, engagements, outcomes, and satisfaction into queryable elements in the knowledge graph. Designed to be lightweight and adaptable — organizations customize the service catalog and maturity model to their operating model.

EA Service Type
Classification of EA services by type — advisory, assessment, design, or intelligence.
Engagement Status
Status of a service engagement in its lifecycle.
EA Maturity Level
Maturity level of the EA function, aligned with Gartner EA Maturity Model. Ranges from Level 1 (ad-hoc) to Level 5 (optimizing).
EA Service
A service offered by the EA function to business and IT stakeholders. Each service has a type, required capabilities, service-level expectations, and a history of engagements. Services are the building blocks of the EA service catalog. Examples: Architecture Review, Technology Radar, Portfolio Assessment, Target State Design, Impact Analysis.
EA Service Catalog
The complete catalog of EA services offered to the organization. Acts as the "menu" of what the EA function provides. Links to the services offered, the EA capabilities available, and the maturity assessment of the EA function.
Service Engagement
An instance of an EA service being delivered to a specific stakeholder or initiative. Tracks the engagement lifecycle from request through delivery to satisfaction assessment. Each engagement has an assigned architect, a status, the element being served (system, capability, initiative), and an outcome.
Service Request
A request for an EA service from a business or IT stakeholder. Records who requested the service, when, and what they need. A request results in a service engagement (or a decline with rationale).
Service Outcome
The measured outcome of a service engagement — deliverables produced, decisions influenced, and value delivered. Links the engagement to its tangible results.
Satisfaction Assessment
Stakeholder satisfaction measurement for a service engagement. Records a numeric score (1-5) and free-text feedback. Used to track EA service quality over time.
EA Capability
A skill or capability within the EA function — not a business capability, but an EA team capability. Examples: ArchiMate modeling, SHACL validation, SPARQL querying, stakeholder facilitation, financial modeling, AI governance. EA capabilities are linked to services (which capabilities are required to deliver each service) and to the service catalog (which capabilities are available in the team).
Distinct from am:Capability (business capability). EACapability describes what the EA team can do, not what the business can do.
EA Maturity Assessment
Assessment of EA function maturity against a maturity model. Records the assessed maturity level, the assessment date, the assessor, and findings/recommendations.
Service Level Expectation
Expected turnaround time, quality, and scope for a service type. Not a binding SLA — an expectation that helps stakeholders understand what to expect when they request an EA service.
EA Value Delivery
Whether the EA function delivers tangible value to the organization — measured through service outcomes, stakeholder satisfaction, and decisions influenced.
EA Capacity Management
Whether the EA function has sufficient capacity and skills to meet demand for its services.
EA Maturity
The maturity of the EA function — from ad-hoc and reactive to optimizing and strategically integrated.
Stakeholder Satisfaction
Whether stakeholders are satisfied with the EA services they receive — quality, timeliness, relevance, and impact.
Overview of all EA services offered — service types, required capabilities, service-level expectations, and engagement history. The entry point for stakeholders seeking EA services.
Engagement Tracking
View of active and completed service engagements — status, assigned architects, stakeholders served, and outcomes. Used for EA workload management and reporting.
EA Capability Portfolio
View of EA team capabilities — which skills are available, which are in demand, and where gaps exist. Used for EA team development and hiring decisions.
View of EA function maturity — current level, assessment history, and improvement roadmap.
View of stakeholder satisfaction across EA services — scores, feedback, and trends. Used for continuous improvement of EA service delivery.
