Abstract. E-procurement solutions can deliver great cost-saving potential for purchasing. But services have not generally been considered as a part of these cost-saving measures. The process of service procurement is often argued to be more complex and less standardized than material procurement. In this paper we propose solutions and standards for service procurement.
Abstract. In this paper we propose a conceptual model for e-procurement solutions for industrial services. Product-related services are of particular interest of companies and should be supported through an appropriate network strategy. However, in the service field, e-business solutions and current standards are still not or only partially considering specifications and related variables of services. We make an approach to develop a conceptual model which allows analyzing existing systems and to specify requirements by distinguishing four system levels. Services can be classified using criteria such as degree of tradeability, intangibility, degree of labor intensity or interaction, etc. In the context of collaborative networks and professional services another common variable is the level of customer contacts or interactions. Services looked at in this paper require close buyer-supplier relationships in nature, and motivate to apply collaborative networks as a strategy, as trust between buyer and seller can be seen as a central focus.
Abstract.A new conceptual design for service procurement networks may surpass existing limitations and bottlenecks. Thereby efficiency can be improved and transaction costs be reduced. To overcome existing limitations a design approach is presented that supports enterprise application integration based on master data and company-wide business process integration. Master data is harmonized with standardized data types and service-oriented architectures (SOA). eBuS-XML is introduced, in the proposed solution it serves as service-specific XML-based library for transaction data types, storage and integration of service e-procurement order processing.
Abstract. Based on recent research in business process modeling and management enhanced integration of resource management can be beneficial. In this context appropriate resources can be identified by matching their profiles with business process requirements. Requirements may be generated from business process models as competence profiles, if advanced modeling techniques that enable detailed modeling are being used. Matching generated profiles to profiles of internal resources (typically maintained by human resource departments) or external business partners (organizations as well as individuals) requires profile descriptions at a similar level of detail. In order to enable sound matching of resource profiles between supplicants and suppliers in collaborative networks, we suggest modeling and system architecture that can handle these challenges. As one main pillar we will present a framework that allows formal description of competence profiles as well as their aggregation to common job profiles; we will outline this approach for the sector of information and communication technology (ICT). Formal description is accomplished by building profiles with the Resource Modeling Language (RML). Regarding architecture we focus on exchange and processing of profile description models. The practical application of our approach is demonstrated by formalization of competence descriptions given by the European eCompetence Framework (eCF).
