Service description and interaction analysis: a multiple actors' view on the BCSM

This paper presents a method which has been developed in the EURESCOM project P509 "Handling Service Interaction in the Service Life Cycle" to describe IN services as perceived from different actors involved in a service's execution. This method called Feature Invocation Model (FIM) provides a graphical description of the relation between the normal call process and the utilized service features. Besides its suitability to clarify the impact of a service's execution on the involved actors, the FIM concept has been mainly promoted in the EURESCOM project P509 to support the detection of service/feature interaction cases. So far, two analysis approaches which differ in their granularity have been developed in order to ease the identification of service combinations that might lead to an undesired interaction because of control flow conflicts.
