- ZeitschriftenartikelA Project Portfolio Management Approach to Tackling the Exploration/Exploitation Trade-off(Business & Information Systems Engineering: Vol. 62, No. 2, 2020) Linhart, Alexander; Röglinger, Maximilian; Stelzl, KatharinaOrganizational ambidexterity (OA) is an essential capability for surviving in dynamic business environments that advocates the simultaneous engagement in exploration and exploitation. Over the last decades, knowledge on OA has substantially matured, covering insights into antecedents, outcomes, and moderators of OA. However, there is little prescriptive knowledge that offers guidance on how to put OA into practice and to tackle the trade-off between exploration and exploitation. To address this gap, the authors adopt the design science research paradigm and propose an economic decision model as artifact. The decision model assists organizations in selecting and scheduling exploration and exploitation projects to become ambidextrous in an economically reasonable manner. As for justificatory knowledge, the decision model draws from prescriptive knowledge on project portfolio management and value-based management, and from descriptive knowledge related to OA to structure the field of action. To evaluate the decision model, its design specification is discussed against theory-backed design objectives and with industry experts. The paper also instantiates the decision model as a software prototype and applies the prototype to a case based on real-world data.
- ZeitschriftenartikelIs it Worth the Effort?(Business & Information Systems Engineering: Vol. 59, No. 2, 2017) Meier, Christian; Kundisch, Dennis; Willeke, JochenThe adequate consideration of resource interactions among IS projects is a challenging but important requirement within IS project portfolio selection. However, the literature does not mention any potential techniques for the identification and assessment of resource interactions. Moreover, the literature has so far neglected the question of the trade-off between time and effort invested in identifying and evaluating resource interactions caused by resource sharing among projects, compared to the benefits derived from this procedure. Hence, the paper’s contribution is twofold. First, a technique to support the identification and evaluation of potentially economically relevant resource interactions is suggested. Second, the paper proposes a decision model that allows to calculate a theoretical upper bound for the amount of effort that should be invested in improving estimates for identified interactions as part of the portfolio planning process.
- ZeitschriftenartikelProduktdifferenzierung für Software-as-a-Service-Anbieter(Wirtschaftsinformatik: Vol. 53, No. 1, 2011) Katzmarzik, ArneDer Markt für das neue Softwarebereitstellungsmodell Software-as-a-Service (SaaS) hat eine beachtliche Größe erreicht und weist weiterhin starke Wachstumsraten auf. Durch eine Produktdifferenzierung können Anbieter ihre Marktposition verbessern und Gewinne vergrößern, in dem sie sich erfolgreich im Spannungsfeld von Kundenakquise, Preissetzung und Kosten bewegen. Im Rahmen dieses Beitrags werden zunächst die Unterschiede bei der Differenzierung von SaaS-Produkten im Vergleich zu auf klassischem Wege bereitgestellter Software untersucht. Dann wird ein mikroökonomisches Modell zur Gewinnmaximierung von SaaS-Anbietern vorgestellt, in welchem die Granularität der Softwareservices optimiert wird. Der Kernbeitrag dieser Arbeit liegt darin, einen Ansatz zur Formalisierung von Überlegungen zur Produktdifferenzierung bei SaaS-Angeboten zu liefern und zudem variable Reproduktionskosten in einem derartigen Modell für Web-basierte Softwareangebote erstmalig zu berücksichtigen. Das Modell wird anhand eines Fallbeispiels mit Daten eines SaaS-Anbieters verdeutlicht.AbstractThe market for the new provisioning type Software-as-a-Service (SaaS) has reached a significant size and still shows enormous growth rates. By varying size of SaaS products, providers can improve their market position and profits by successfully acting in the tension area of customer acquisition, pricing and costs. We first elaborate differences concerning product differentiation between classic software provisioning models and SaaS. Then, we introduce a micro-economic based decision model to maximize the return of a provider by finding an optimal granularity, i.e. by varying the size of services. This paper makes two contributions in this context: (1) it provides a conceptual foundation for product differentiation within the scope of SaaS and (2) it presents the first implementation of variable reproduction costs for web based software offers. The model is illustrated by a real world case with data from a SaaS provider.
