    Decision Support for IT Investment Projects
    (Business & Information Systems Engineering: Vol. 58, No. 6, 2016) Müller, Marcel Philipp; Stöckl, Sebastian; Zimmermann, Steffen; Heinrich, Bernd
    Managerial flexibilities have to be taken into account in ex-ante decision-making on IT investment projects (ITIPs). In many papers of the IS literature, standard financial option pricing models are used to value such managerial flexibilities. Based on a review of the related literature, the paper critically discusses the assumptions of the most frequently used financial option pricing model, namely the Black–Scholes model, arguing for relaxed assumptions that better represent the characteristics of ITIPs. The authors find that existing real option analysis approaches featured in the IS, Finance, and Economics literature are unable to consider more than two of our relaxed assumptions. Consequently, they present their own approach in form of a simulation model for the valuation of real options in ITIPs which offers a better representation of the characteristics of ITIPs by taking the discounted cash-flows and the runtime to be uncertain as well as the market to be incomplete. Based on these modifications of the Black–Scholes model’s assumptions, it is found that the resulting option value contains idiosyncratic risk that has to be taken into account in ITIP decision making. For the realistic case of risk averse decision makers, the consideration of idiosyncratic risk usually leads to a lower risk-adjusted option value, compared to one calculated by means of the Black–Scholes model. This confirms the perception of managers who feel that financial option pricing models frequently overvalue ITIPs and hence may induce flawed investment decisions.

    On the Ex Ante Valuation of IT Service Investments
    (Business & Information Systems Engineering: Vol. 58, No. 6, 2016) Buhl, Hans Ulrich; Häckel, Björn Steven; Probst, Florian; Schosser, Josef
    The paradigm of service orientation and its incarnation in the form of service-oriented architecture (SOA) and information technology (IT) services play a crucial role in enabling companies to achieve considerable competitive advantages. However, to be able to leverage the opportunities of SOA and IT services, companies need to gain a thorough understanding of the business value of IT service investments. Nevertheless, research on IT services has focused mainly on technical questions so far; the economic perspective largely has been neglected. Therefore, the authors aim to contribute to the ex ante valuation of IT service investments from a decision theoretical point of view. Using decision theory as a theoretical base, the main aim is to identify and discuss specific challenges regarding the financial ex ante valuation of IT service investments, which arise from the inherent flexibility of IT services and the various interdependencies within a company’s IT service portfolio. The authors thereby emphasize that the application of common methods from financial theory for valuating IT service investments has to be treated with caution, as these methods are often tied to rather restrictive assumptions based on the specifics of capital markets. By analyzing different clusters of IT service investment decision problems using decision theory, the authors identify and discuss pitfalls that might occur when applying financial valuation methods to capture the flexibility and interdependencies of IT service investments. The decision theoretical considerations are intended to help build a solid basis for future multi-criteria valuation approaches, of which an essential component is a theoretically well-founded financial valuation.

    Evaluation Methods in Process-Aware Information Systems Research with a Perspective on Human Orientation
    (Business & Information Systems Engineering: Vol. 58, No. 6, 2016) Kriglstein, Simone; Leitner, Maria; Kabicher-Fuchs, Sonja; Rinderle-Ma, Stefanie
    Research on process-aware information systems (PAIS) has experienced a dramatic growth in recent years. Lately, a particular increase of empirical studies and focus on human oriented research questions could be observed, leading to an expansion of applied evaluation methods in PAIS research. At the same time, it can be observed that evaluation methods are not always applied in a systematic manner and related terminology is at times used in an ambiguous way. Hence, the paper aims at investigating evaluation methods that are typically employed in PAIS research with a special focus on human orientation. The applied methodology includes a literature review, an expert survey, and a focus group. The authors present their findings as a collection of typical evaluation methods and the related PAIS artifacts. They highlight which evaluation methods are currently used and which evaluation methods could be of interest for future PAIS research efforts.
