An ultimate goal of an SOA transition effort is to produce a collection of standardized services that comprise an SOA service inventory. The inventory can be structured into layers according to the service models used, but it is the application of the service-orientation paradigm to all services that positions them as valuable IT assets in full alignment with the strategic goals associated with the SOA project.

However, before any SOA services are actually built, it is desirable to establish a conceptual blueprint of all the planned services for a given inventory. This perspective is documented in the service inventory blueprint. There are several common business and data models that, if they exist within an organization, can provide valuable input for this specification. Examples include business entity models, logical data models, canonical data and message models, ontologies, and other information architecture models.
A SOA service inventory blueprint is also known as a service enterprise model or a service inventory model.
