    Enhancing Service Lifecycle Management - Costing as Part of Service Descriptions
    (Association for Information Systems, 2013-08-15) ; ;
    Outsourcing of IT and business processes results in an increased exchange of services. For inter-organizational service exchange to be successful, the participating network players have to establish unified and thus interoperable means of service description. An analysis of contemporary approaches identified a deficit of almost all approaches to address monetary aspects of a service, especially costs. This paper argues that costs are prevalent in almost all stages of a services' lifecycle, and thus its' role within Service Lifecycle Management (SLM) is paramount. Recognizing this discrepancy, the paper proposes a basic version of a costing model that allows for a multi-periodic depiction of service-related costs as part of a service description. It is modeled and implemented as an extension of USDL, the Unified Service Description Language. A case example from the financial services industry demonstrates the artifact's applicability.

    Supporting Service Management with Graph-based Service System Visualization, Manipulation and Analysis
    (Association for Information Systems, 2013-08-15) ; ;
    The ability to establish and maintain connections to business partners has become a critical success factor in many businesses. Service-oriented architectures are being intensively discussed as an enabler on both business- and technical level. The management of services in a SOA requires comprehensive information about the managed services. Several approaches for unified service descriptions emerged, e.g. the Unified Service Description Language. Even small service systems can comprise a considerable number of different services, relationships and resources, which in turn requires (semi-)automated means supporting the analysis and manipulation. This paper builds on the Unified Service Description Language and derives a model for the graph-based visualization, manipulation and analysis of service systems. The proposed model supports service management tasks, including but not limited to redundancy detection and documentation, make-or-buy simulations and service costing. The results are prototypically implemented and applied to a case example from the financial services industry.
