In SAP Service Cloud Version 2, "Installed Base" and "Measurements" are two of the services that can be added to a business role. The Installed Base service allows for the management and tracking of a customer's installed products or equipment, enabling service agents to have a comprehensive view of the customer's assets for better service and support. The Measurements service, on the other hand, enables the tracking and recording of various metrics or performance indicators related to the installed base or service processes. This service is crucial for monitoring performance, ensuring quality, and making informed decisions based on empirical data.
