PublicationTowards computer aided IT service engineeringIncreasing demand for cost-efficiency and customer-orientation leads to the need for professionalization in all stages of the information systems' lifecycle. Standardization and automatization of provision and delivery processes are commonly adequate means to reach a higher level of maturity in the operations and maintenance stage. A prerequisite is that corresponding processes are also designed in the development stage of information systems and reused if possible. Commonly, IT services encapsulate these processes. Reusability of IT services is often achieved by decomposing them in modular IT service components. But customer-orientation and individualization decrease reusability of each IT service component. Hence, the complexity in the design stage rises due to the variety and the enormous amount of IT service components. Besides, permanent changes of the customer's needs also reinforce this situation. To assure the reusability of former created IT service components we suggest implementing a repository for these components. An efficient retrieval in the repository strongly relies on well-defined specifications of these components. In this paper we contribute to a reference data model to structure the repository of IT service components.Type: conference paper

PublicationVariant configuration for IT-services and its impact on the service request fulfillment process( 2011-08-05)IT organizations are currently facing a trade-off between standardization and customer individuality. Standardization is onemeans to realize scale economies, is prerequisite to automate the delivery of IT-services and hence a possibility to cut costs.Best-practice frameworks like ITIL also drive the standardization efforts by defining IT-service catalogues and standardprocesses. Upcoming or rather ongoing trends like on-demand computing require standardization to assure efficientallocation of resources. But on the other hand customers of IT-services are confronted with increasing competition in theirbusiness that provokes individuality of their processes. Consequently IT-services must also be adjustable or customizable tomeet the customers’ needs. The resulting variety must be handled efficiently by the IT organization to stay or becomecompetitive. One means to cope with variety in the service request fulfillment process is variant configuration. In ourcontribution we discuss how variant configuration mechanisms can be applied on IT-services and what impact variantconfiguration has for the service request fulfillment process.Type: conference paper
