Alignment Verification in the Early Stage of Service Design

Alain Wegmann, Gorica Tapandjieva Sekulovska, Matteo Filipponi

Verification is a costly task, sometimes burdensome and tedious, requiring strong formal background. To reduce the effort and cost invested in verification, we developed a model-driven approach for automatic verification of service properties, done in the ...

IT Service Alignment Verification of Quantitative Properties in Service Design

Alain Wegmann, Gorica Tapandjieva Sekulovska

Despite many years of research, alignment of business and IT services remains a challenge. In this paper we show how to verify the quantitative properties of a service against stakeholder requirements during service design. We model the service with the Sy ...

Specification and Implementation of a Meta-model for Information Systems Cartography

Alain Wegmann, Gorica Tapandjieva Sekulovska

Models are used in software engineering, enterprise architecture, requirements engineering, etc. In this context, models can give support in creating a shared understanding of what exists in an enterprise. For this purpose we suggest to use a cartography t ...

Patterns for Value-Added Services Illustrated with SEAM

Alain Wegmann, Gorica Tapandjieva Sekulovska, Aarthi Gopal, Maude Laetitia Grossan

The basic idea behind the provision of a service is to hide the service implementation details from the client in such a way that more value is provided to the client. Very often support services allow too much of their implementation details to be visible ...
