    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.

    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.

    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.

    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.

    AVENTEON Mobile Business Assistant
    (Wirtschaftsinformatik: Vol. 47, No. 1, 2005) Habermann, Kai
    With the emergence of new mobile data technologies such as GPRS, WLAN and UMTS, corporations now realize that it is possible for the first time to create “real-time” mobile business processes that can truly deliver greater efficiencies at the business process level. ‘Realtime’ here refers to constant data exchanges that ultimately enable seamless interactions between central planners and mobile workers.As with most IT investments, the key factor that will lead to the adoption of mobile business processes among enterprises will be the generation of a positive “mobile” Return on Investment (mROI) based on a stable business case. This can be best performed in an ongoing iterative approach where learning from the current implemented process is always used for further process improvements.This paper primarily examines how existing mobile business processes can be optimized in order to deliver truly greater business process efficiencies for companies that are looking to deploy mobile solutions and also examines some of the best practices that enterprises should consider before making any substantial investment decision into a new mobile process.Finally the paper takes a look at the Aventeon Mobile Business Assistant (MBA) which is a new, cutting edge software that is particularly designed for creation and optimization of “Real-time Mobile Business Processes”. The MBA offers specific products for key verticals including utilities, repair services, logistics, sales and pharmaceuticals. In the development, the MBA strictly follows the key success factors of a process oriented mobile solution and is set up to deal with the complex challenges of the mobile business world.
