As the number of candidate services increases, an unstructured list can quickly become unmanageable. Therefore, as soon as possible a service classification scheme needs to be
identified so that candidate services can be organized into groups within the classification hierarchy. The Service
Hierarchy organizes services in the service portfolio using a uniform classification scheme. The classification scheme is often based on the functional areas identified by
RUP/SOMA Domain Decomposition Functional Area Analysis. Notation for the
Service Hierarchy in an outline format is shown in below.

While a simple list of service names can be a quick starting point, it will eventually be important to capture
additional information about each service. This information can be
subdivided into two types: information that supports service identification, and information that supports service
specification.
Service
identification is focused on building a portfolio of services that can be associated with business functions, business
goals, assets such as existing systems, and an indication of whether the service is considered a candidate service, or
has been chosen for exposure. Table 2 in Template: Service Model in Word can be used to document services at the level of
detail needed in the service portfolio.
