    Innovationspotenzial von RFID für das Supply-Chain-Management
    (Wirtschaftsinformatik: Vol. 47, No. 1, 2005) Strassner, Martin; Fleisch, Elgar
    RFID (Radio Frequency Identification) supports Supply-Chain-Management processes through automated identification and data acquisition. Hence it is an enabler for seamless integration of physical resources with IT-systems. On the example of the automotive industry this article shows how the supply chain can benefit from the integration of physical resources, how companies can proceed with the adoption of RFID and what critical success factors they must consider. A higher degree of integration and automation improves process efficiency and quality, which reduces manual labour and failure costs. Case studies show that these cost savings can justify the investment in RFID systems. Companies can adopt RFID step by step in order to minimize their investment risk and to achieve an efficient degree of integration. Before they start with the implementation of RFID systems, they should determine their own need and consider economic and technical requirements. The dynamic of technology and the market will simultaneously favour the expansion of RFID in Supply-Chain-Management applications.

    Technische Möglichkeiten und Akzeptanz mobiler Anwendungen
    (Wirtschaftsinformatik: Vol. 47, No. 1, 2005) Hess, Thomas; Figge, Stefan; Hanekop, Heidemarie; Hochstatter, Iris; Rauscher, Barbara; Hogrefe, Dieter; Riedel, André; Zibull, Marco; Kaspar, Christian; Richter, Markus
    Mobile data communication applications, referred to in this paper as mobile applications, were one of the technological innovation and investment targets in recent years. From the past it became obvious that mono-disciplinary approaches to investigate mobile applications have shortcomings when it comes to successful innovation and investment decisions as interdependencies are insufficiently addressed. The paper therefore aims at structuring the scientific contributions of computer science, business economics and sociology in the context of mobile applications to approximate a holistic understanding comprising technological feasibility, economic opportunities and human needs.

    This article describes the iManual-concept developed at Fraunhofer FIT which deals with the use of mobile devices as context-aware integrated control and help systems for in principal arbitrary wirelessly connected consumer or industrial products. Following the premise of designing the interface of various IT-based products in a way that facilitates learning and respects user expectations, we explore the design space that is created by combining control and help functions by way of mobile devices. On the way, we discuss various potentials of this approach to enhance the corresponding products and services. Based on a review of the state of the art on intelligent help systems and mobile interfaces we describe the iManual concept and a prototypical implementation for a PDA-based control and help system for the navigation system of the BMW 7. We conclude with a discussion of limitations and opportunities for extension of the approach and corresponding further work.

    Strategy Alignment of Mobile Solutions in Customer-Oriented Processes
    (Wirtschaftsinformatik: Vol. 47, No. 1, 2005) Schierholz, Ragnar; Kolbe, Lutz; Brenner, Walter
    In this paper we analyze how companies define their strategy, especially how they interact with and appear to the customer. Based on a framework of five goals in customer oriented strategy, we classify seven cases. Analyzing the strategic premises and the processes chosen to be supported by mobile solutions, we show interdependencies between the strategic premises and the selected processes, resulting in typical properties which qualify processes for mobilization.

    Ubiquitous Customer Interface
    (Wirtschaftsinformatik: Vol. 47, No. 1, 2005) Robra-Bissantz, Susanne
    A Ubiquitous Customer Interface (UCI) is a concept for the different stationary and mobile media that are used in companies’ contact with private customers. Via the UCI contents are distributed to a mobile customer at any time and to any place, but under the condition that the supplier considers customers’ needs regarding media and content preferences. In this paper approaches for a UCI are developed from a customer’s point of view. An empirical study shows that customers in e-commerce find themselves in five different types of situation during the routine of a day. These types of situation have an impact on the preferred media and on the special need for information. The variable that determines the description of the types of situation is the mood of the customer. Based on these insights the concept of the UCI is transferred to the example of a financial service provider.
