Service asset

Definition
Service assets fall into two classes: internal and external.


 * Internal service assets (e.g., customer service systems, enterprise networks, operations support) are those that provide internal functions for increased productivity and efficiency.
 * External services include those that provide service offerings or promote some other essential business function (e.g., Web servers for advertising, marketing, and customer relations).
