On the source side, a service type (Business service symbol) must be linked to an application system type (Software service type symbol) via a connection of the supports type. The relationship between a business service and a software service type must be modeled in a service allocation diagram that is assigned to the business service. The software service type is included only if exactly one service exists for the business service.

The application system type (Software service type symbol) must be the same as in the image above. The connection between the application system type (Software service type symbol) and the IT function type (Software service operation type symbol) must be included in the application system type diagram assigned to the software service type. The software service operation type is only contained if it is the only one for the software service type.
