The Bottom Line

Services realize Capabilities — the most foundational of the inter-inventory relationships. The Capability is the standing ability the enterprise possesses; the Service is the deliberate, contracted, governed offering through which that ability becomes operationally available to a Service Requester Community. Many-to-many: one Capability may be realized by many Services; one Service may realize many Capabilities.

Core Concepts

ConceptDefinition & Strategic Role
CapabilityThe standing enterprise ability — what the enterprise can do — governed in the IF4IT Capabilities Inventory and Attributes.
RealizationThe relationship where a Service makes a Capability operationally available — without Services, Capabilities remain abstract.
Many-to-Many StructureOne Capability may be realized by multiple Services (different Requester Communities or delivery models); one Service may realize multiple Capabilities.

Quick Q&A

Question: What does a Capability with no realizing Services indicate?

Answer: An unrealized strategic intent — the enterprise claims to have the Capability but has no governed Service through which it becomes operationally available to Service Requesters. This is a gap that Enterprise Architecture and the Service Management Office should surface and address — either by defining new Services to realize the Capability or by re-evaluating whether the Capability claim is accurate.

Question: What does a Service that realizes no Capability indicate?

Answer: A misclassified activity — the Service may not actually be a Service at all (it may be a Process, a team activity, or an informal offering) or it may be a Service whose Capability link has not yet been articulated. Either way, the Service Owner should work with Enterprise Architecture to either map the Service to a Capability or reconsider whether it belongs in the inventory.

Services realize Capabilities. Every governed Service exists to make one or more Capabilities operationally available to a Service Requester Community. The Capability is the standing ability the enterprise possesses; the Service is the deliberate, contracted, governed offering through which that ability becomes accessible. The Services Inventory connects to the IF4IT Capabilities Inventory and Attributes through the Capability Realization attribute in the Strategic Attributes category.

A Capability without any Services realizing it is an unrealized strategic intent; a Service that does not realize a Capability is a misclassified activity. This relationship enables enterprise-wide analysis of which Capabilities are well-supported by Services, which are under-served, and where the Service portfolio is misaligned with Capability strategy. The relationship is many-to-many: one Capability may be realized by multiple Services (each realizing the Capability for a different Service Requester Community or through a different delivery model), and one Service may realize multiple Capabilities (where the Service contributes to several enterprise abilities).
