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.
