+====== 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.
