Service Catalog

A service catalog documents customer-facing and internal services—what they deliver, who owns them, dependencies, and performance commitments. It connects business consumption to underlying applications and infrastructure. Catalogs support chargeback, demand management, and transformation impact communication.

In Practice

Larkinized LLC maps catalog services to capabilities and applications in the repository for end-to-end traceability. Service introductions and retirements follow architecture review when dependencies are shared. ITIL and EA catalogs should share identifiers to reduce duplication.

Example

An HR onboarding service catalog entry lists dependent identity, payroll, and learning systems with defined SLAs.
