ARCHITECTURE CONCEPTS FOR VALUE NETWORKS IN THE SERVICE INDUSTRY

Value networks are one of the main forms of value creation today. Suppliers, manufacturers and customers form a dynamic collaboration structure. Networks and companies alike are always subject to external and internal influences which require changes in the way things are done. To make sure that the required changes take their intended effect, they have to be implemented on all levels of the enterprise architecture (EA). Research with respect to EA in value networks in the service industry (VNSI) is only in its beginnings. To understand the state of the art, we analyzed 88 papers with respect to the architecture layers in VNSI. Since we base on the fact that a successful introduction of change, e.g. new IT solutions, requires a holistic view on EA, we analyzed the papers according to their covering of the different levels of an EA. Our hypothesis is that most of the papers only cover very specific aspects without positioning their proposed solution in a holistic context. We propose a reference model based on a literature review as well as the results of the paper analysis. This reference model allows for a positioning of solutions in a holistic context and with that adds to a better basis for implementing change in VNSI

LEISTUNGSORIENTIERTE STEUERUNG DER INFORMATIONSVERSORGUNG IM RAHMEN DER QUALITÄTSSICHERUNG IN DIENSTLEISTUNGSNETZWERKEN

Die Qualitätssicherung der Leistungserstellung in Dienstleistungsnetzwerken ist ein wichtiger Erfolgsfaktor. Die Netzwerkunternehmen müssen durch eine effektive und effiziente Informationsversorgung unterstützt werden. Eine leistungsorientierte Steuerung der integrierten Informationsversorgung sowohl auf organisatorischer als auch auf technologischer Ebene trägt den Herausforderungen Rechnung. Drei Szenarien bilden die unterschiedlichen Anforderungen in Bezug auf Flexibilität und Unabhängigkeit der Netzwerkunternehmen ab. Sie werden durch Kriterien definiert, die auf die leistungsorientierte Gestaltung der Informationsversorgung ausgerichtet sind: Ziele der Informationsversorgung, Ausgangs- und Eingangsdaten sowie Prozesse. Daraus leiten sich Architekturen sowie Rollen und Verantwortlichkeiten ab. Zur Steuerung werden drei korrespondierende Controllingansätze entwickelt, die für jede Architektur spezifische Controllingobjekte, Controllinginstrumente sowie quantitative und qualitative Kennzahlen zur Verfügung stellen

A Classification Scheme for Characterizing Service Networks

This paper introduces an extended definition of service networks. The service network definition, which can be used for classifying service networks, comprises two parts: the service network declaration and the service network specification. The service network specification consists of the specification of the network characteristics, the node characteristics, and the link characteristics. Each of these three characteristics comprises a set of criteria. One fraction of the criteria has been identified through literature research on services, networked organizations, and service network concepts. The remaining fraction of criteria is the result of a case study analysis. The service network case study has been taken from the information technology sector (i.e., the network of Cloud computing services). The analysis of the case study identified characteristics that are important for describing IT service networks but cannot be captured with the existing definitions of service networks
