    Heavy equipment manufacturing firms are increasingly challenged by the integration of service planning and execution in their established product-centred information systems (IS) environment. Despite a few standardisation efforts, there is no common understanding of service systems in industry goods companies and the corresponding requirements for the appropriation of information systems. We address this need by developing a maturity model. The design of the model is grounded in extant literature, focus group and case study research involving eleven organisations over 1.5 years. The evaluation confirms that the maturity model makes a novel and useful contribution to the design of service systems

    The constantly rising fraction of industrial services reveals the structural economic change that is changing the manufacturing industry landscape. Manufacturing firms have more and more problems to find the appropriate information technology (IT) solution for planning and execution as they are confronted with the strategic challenge of reducing operating costs while at the same time meeting ever-increasing industrial service demands. Despite the existence of some standardization efforts dealing with product-related services, there is no common understanding of product-service systems and the corresponding processes and IT systems among manufacturing companies. This paper addresses this need by developing a maturity model capturing the key requirements for the information systems (IS) support of product-service systems based on a multiple case study. Further, we confronted these requirements with scientifically recognized maturity models and standard specifications developed by the German Standards Institute. The development of the maturity model is grounded in the design science research approach and is evaluated by managerial experts.

    Fostering Efficiency in Information Systems Support for Product-Service Systems in the Manufacturing Industry

    The ongoing shift towards stronger service orientation is leading to a rising number of industrial services offered in the manufacturing industry. In the attempt to fulfill ever-increasing service demands while at the same time reducing operating costs, manufacturing firms search for appropriate information technology (IT) solution for planning and execution. The industry has not yet reached a common understanding of product-service systems and the corresponding processes and IT systems. In order to holistically support such broad design and transformation tasks, we develop a maturity model capturing the key requirements for the information systems (IS) support of product-service systems based on a multiple case study. For a critical reflection on the extant literature, we compared those requirements with scientifically recognized maturity models and standard specifications. Being an integral part of the design science research approach, the model evaluation is organized in accordance with approved evaluation perspectives.

    IT Governance in Multi-Business Organizations: Performance Impacts and Levers from Processes, Structures, and Relational Mechanisms

    IT governance is more than ever recognized as a panacea by IT managers to ensure effective and efficient IT operation in multi-business organizations. The aim of this paper is to analyze the performance impact of IT governance. In order to do so, the study takes the resource-based perspective, and integrates the economic theory of complementarities and the concept of relatedness. The proposed increase in business process performance is grounded in the generation of sustainable competitive advantage. The framework is investigated by using five exploratory case studies in multi-business organizations. The results suggest that IT governance is positively related to business process performance through the mediators of IT relatedness and business process relatedness. Furthermore, IT governance levers have been identified which might significantly increase business process performance.

    The Influence of Information Technology on Industrial Services in the Manufacturing Industry - A Literature Review and Future Research Directions

    In the last 40 years, industrial organizations have optimised their production processes through information technology (IT). Nowadays, manufacturing firms are confronted with shrinking margins, service-demanding customers, and increased competition that are associated with the structural shift from a product-dominant to a service-dominant economy. In order to answer the changed market conditions, those firms started to offer industrial product-service systems that refer to customer life cycle oriented combinations of products and services realised in an extended value-creation network. Since enterprise information systems (IS) are designed and optimised for production planning, a clear lack in functionality and integration for industrial services can be ascertained. In particular, the life cycle management for product-service systems is not adequately covered in current standard software solutions. Firms heavily rely on individual software instead. Due to the cross-disciplinary field of research, it is important to have an overview of the extant literature. Therefore, we present a structured literature review grounded in an established literature review framework. The results suggest that extant literature lacks depth in covering the specificity of industrial services in IT solutions supporting life cycle management. We propose further research in requirements engineering, IT architecture, IT infrastructure, IT governance, and sourcing.

    IT Shared Service Center and External Market Activities

    In the last few years many corporate groups reorganized their IT-Services and established IT Shared Service Centers (IT SSC). These IT SSCs primarily delivered IT services internally; nevertheless some IT SSC provided IT services to external customers as well. These external market activities failed in most cases. In spite of the relevance to organizations, little research has been done investigating the reasons for such failures. In order to address this issue, we have conducted a qualitative study with eight IT SSC cases and five experts interviews. We have triangulated the results between the case studies and the expert interviews and we have identified two set of factors, one explaining IT SCC successes in internal markets and the other explaining IT SSC failures in external markets. The enabling factors for the successes of IT SSCs in internal markets include having the same corporate culture, knowledge of the parent organization and its processes, lower transactions cost, lower average cost, no dependence on external IT service providers, better data protection, improved IT opportunities and obligation to provide services. The factors explaining external market failures include the lack of experience with acquisition, no professional sales and marketing, lack of investment funds, weak unique features of IT services, reassessment of strategic group portfolio by the parent company, higher IT service costs, and inconsistent business models. These findings are relevant to managers of IT SSCs to make decisions on their corporate strategy, as well as to researchers to utilize these findings as a starting point for future research on IT SSCs.
