Example of a Service Interface using Service Operations
The service operation “Customer identification” starts with customer research step. If the customer is found, the protocol returns customer information, if not, a "Customer Creation" protocol is activated. The result of the “Customer identification” service interface is the “Information about customer” message.
Service interface Diagram (BPMN)
The steps are represented by used service operations and used service interfaces.
A service operation use represents the usage of a service operation in an service interface.A service interface use is associated to a service interface. It enables representation of complex exchanges.Example of a service interface using service interfaces
With HOPEX Business Process Analysis, a protocol is described by a sequence flow of steps which are represented:
• By used service operations
• By used service interfaces
The protocol roles, presented at the border of the frame, represent participants invoker or invoked.
A service interface can be described by involving more than two participants. In this case, a role is consumer of the service interface and the others are providers.
“Information Requirement” Service Interface (BPMN) diagram
The "Information Request" service interface is used by the supplier call center to take account of a customer request online. There are therefore three participants in this contract: the customer, the IT applications and the customer representative who is the effective requester of the service (in this case the call center).
This contract consists of identifying the customer, then analyzing the request. The request is then processed as a purchase request or as another request if it is an information request for example.
