ABSTRACT:
This paper presents experiences in requirements engineering analysis, service identification, and service specification that were gained during a service development project in a public government organization. These experiences resulted in a method comprising techniques relying on a combination of BPMN 2.0 and UML. This method shows that using a combination of these notations and model generation of IT artifacts leads to fewer documents for different stakeholders, alignment of service specifications to original requirements, and semantic unambiguousness for service specifications.
