    Theory: Argumentation is crucial for all academic disciplines. Nevertheless, a lack of argumentation skills among students is evident. Two core aspects of argumentation are the recognition of argument structures (e.g., backing up claims with premises, according to the Toulmin model) and the recognition of fallacies. As both aspects may be related to content knowledge, students studying different subjects might exhibit different argumentation skills depending on whether the content is drawn from their own or from a foreign subject. Therefore, we developed an instrument to measure the recognition of both argument structures and fallacies among the groups of preservice teachers and business economics students in both their respective domains (pedagogy and economics), and a neutral domain (sustainability). For the recognition of fallacies, we distinguished between congruent and incongruent fallacies. In congruent fallacies, the two aspects of argument quality, i.e., deductive validity and inductive strength, provide converging evidence against high argument quality. In incongruent fallacies, these two aspects diverge. Based on dual process theories, we expected to observe differences in the recognition of congruent and incongruent fallacies. Aims: We investigated whether these two abilities are domain-specific and whether the recognition of fallacies depends on the congruence of two aspects of argument quality. Methods: 267 preservice teachers and 56 business economics students participated in the study. For the recognition of argument structures, participants assigned the five statements constituting one argument to the corresponding component according to the Toulmin model. For the recognition of fallacies, we created arguments and incorporated a common fallacy into some of them: formal fallacy, overgeneralization, irrelevance, or circularity. Participants rated whether the argument was cogent or not, which was followed by a brief justification. Results: Domain specificity could not be found for either of both abilities. For the recognition of fallacies, two dimensions were found: a congruent dimension (formal fallacies and overgeneralizations) and an incongruent dimension (irrelevance and circularity). Discussion: The instrument measures the recognition of both argument structures and fallacies in these two groups across domains. The recognition of fallacies differs depending on whether the deductive validity and the inductive strength of the argument are equally indicative of argument quality or not.

    Meditec is a German manufacturer of instruments for surgeries. The company is quality leader in this sector and supplies many German and international hospitals. However, the opportunities for differentiation against competitors decrease continuously. New competi- tors from emerging markets are challenging the market position of established companies in this industry. Meditec is therefore forced to change its strategy and business model in order to survive in this novel competitive environment. The management of Meditec has decided to traverse from a pure product manufacturer to a customer-centric solution provider. This transformation requires the development of new processes, competencies and capabilities - especially with respect to IT and IT services. This teaching case helps in understanding the role of IT in product-service systems (PSS) and PSS-based business models. Therefore the case illustrates why IT is necessary to establish a PSS-based business model and why a customer-centric view is important for this kind of business model.

    Why can't I use my iPhone at work?: managing consumerization of IT at a multi-national organization

    As IT innovations in the last years emerged on the consumer market, employees are more experienced in the private than in the corporate use of innovative IT devices and applications. These employees, familiar with the benefits consumer products offer, expect those to be provided by their corporate IT. This trend, referred to as ‘consumerization of IT', leads to more and more consumer innovations infiltrating companies. In particular, mobile consumer devices are currently spreading into companies, strongly pushed by top manage- ment, and create several challenges to Chief Information Officers (CIOs) around the globe: ‘What IT costs are associated with the use of mobile consumer devices?', ‘How will corporate use of mobile consumer devices affect IT management?', and ‘How to introduce an IT service for corporate as well as personal mobile consumer devices?'. OMEGA Group, a multi-national company with 50,000 employees, wants to leverage the potential of mobile consumer devices for corporate purposes. Therefore, these questions have to be addressed and answered by its CIO. The teaching case is designed to introduce the char- acteristics of consumerization and associated challenges for IT management. The case uses selected information systems methodologies and frameworks.
