In this ArchiMate diagram example, external and internal business services are distinguished. The Basic administration function acts as a shared service center. The take out business processes corresponding with the travel and luggage insurance use the (internal) business services that are provided by the Basic administration function. Both business processes realize an (external) business service. The insurance selling service is accessible via a business interface (e.g., web form) of the insurance seller. Each business service should be of value to the user(s) of the service (in this example, the insurance buyer role). This value may be explicitly modeled, if appropriate. The value of the Travel insurance selling service to an external customer (the insurance buyer) is that the customer is insured.
