Service Portfolio

Service Portfolio: Internal list that details all the services offered by a service provider, including those in preparation, live and discontinued.

Service: Way to provide value to customers through bringing about results that they want to achieve.

Service component: Logical part of a service that provides a function enabling or enhancing a service.

NOTE: A service is usually composed of several service components.

NOTE: Although a service component underlies one or more services, it usually does not create value for a customer alone and is therefore not a service by itself.
