Business Models: An Information Systems Research Agenda

The business model concept, although a relatively new topic for research, has garnered growing attention over the past decade. Whilst it has been robustly defined, the concept has so far attracted very little substantive research. In the context of the wide-spread digitization of businesses and society at large, the logic inherent in a business model has become critical for business success and, hence, a focus for academic inquiry. The business model concept is identified as the missing link between business strategy, processes, and Information Technology (IT). The authors argue that the BISE community offers distinct and unique competencies (e.g., translating business strategies into IT systems, managing business and IT processes, etc.) that can be harnessed for significant research contributions to this field. Within this research gap three distinct streams are delineated, namely, business models in IT industries, IT enabled or digital business models, and IT support for developing and managing business models. For these streams, the current state of the art, suggest critical research questions, and suitable research methodologies are outlined.

Classroom Response Systems

Lehre in Zeiten groser Horerzahlen In vielen Fachdisziplinen werden – insbesondere in Bachelorstudiengangen – obligatorisch zu belegende, einfuhrende Grundlagenveranstaltungen als klassische Frontalvorlesungen angeboten. In stark nachgefragten Studienfachern fuhrt dies haufig zu sehr hohen Teilnehmerzahlen (> 1000). In solchen Veranstaltungen bleibt den Studierenden im Normalfall nur die Rolle passiver Rezipienten, die sich den Vortrag des Dozenten anhoren und sich die dargebotenen Inhalte auf unterschiedlichenWegennach der Veranstaltung individuell erschliesen. Diese Form des Lernens ist angesichts mittlerweile gut fundierter Erkenntnisse der Lehr-/Lernforschung nicht optimal. Konstruktivistische Lerntheorien verstehen erfolgversprechendes Lernen als aktive Auseinandersetzung des Lernendenmit demGegenstandsbereich und begreifen den Wissenserwerb als subjektiven Konstruktionsprozess von wahrgenommener Wirklichkeit [3]. Um diesen Prozess anzuregen, werden haufig handlungsorientierte Formen der Didaktik vorgeschlagen, bei denen die Lernenden zu aktiver und selbststandigerMitarbeit angeregt werden sollen [4]. Solches Lernen in Kooperation mit anderen kann erganzende Vorteile bieten, da ein kritischer Diskurs mit divergierenden Positionen der Klarung und Prazisierung des eigenenWissens dienen kann sowie Teamkompetenzen entwickelt werden konnen, die auch im kunftigen Berufsleben der Studierenden von Bedeutung sind. Es stellt sich daher die Frage, wie auch in grosen

Geschäftsmodelle - Eine Forschungsagenda für die Wirtschaftsinformatik.

Obwohl das Geschaftsmodellkonzept ein noch relativ junges Forschungsgebiet ist, hat es im letzten Jahrzehnt zunehmend an Beachtung gewonnen. Trotz einer Vielzahl grundlegender Definitionen des Geschaftsmodellkonzepts hat es bislang dennoch nur sehr wenig bedeutende Forschung angezogen. Im Kontext der weit verbreiteten und kontinuierlichen Digitalisierung von Unternehmen sowie der Gesellschaft als Ganzes wurde die in einem Geschaftsmodell (GM) enthaltene Logik kritisch fur den Geschaftserfolg und somit ein Fokus fur akademische Forschung. In unserem Beitrag betrachten wir das Geschaftsmodellkonzept als ein fehlendes Bindeglied zwischen der Strategie und den Geschaftsprozessen. Wir argumentieren, dass die Wirtschaftsinformatik-Gemeinschaft spezifische und einzigartige Kompetenzen bietet (z. B. Ubertragung von Geschaftsstrategien in IT-Systeme, Management von Unternehmen und IT-Prozessen, etc.), die fur bedeutende Forschungsbeitrage auf diesem Gebiet genutzt werden konnen. Innerhalb dieser Forschungslucke grenzen wir drei wesentliche Forschungsschwerpunkte ab: Geschaftsmodelle in der IT-Industrie; durch IT ermoglichte oder digitale Geschaftsmodelle; sowie IT-Support fur die Entwicklung und das Management von Geschaftsmodellen. Fur diese Forschungsfragen skizzieren wir den State of the Art sowie kritische Forschungsfragen und schlagen passende Forschungsmethoden fur deren Beantwortung vor.

It sourcing portfolio management for it services providers: an approach for using modern portfolio theory to allocate software development projects to available sites

Global sourcing of Information Technology (IT) work has become a widely accepted practice among transnational corporations. Most of the big IT Services Providers (ITSPs) maintain a portfolio of globally distributed delivery centers and have to decide on the assignment of specific software development projects to their available sites. ITSPs have to consider expected costs, risks, and interdependencies between projects and sites when making value-based sourcing decisions. However, value-based decision approaches that are both well founded in theory and applicable in practice have until now been missing in the Information Systems literature. As decision making with respect to the construction of portfolios of risky financial assets exhibits similar characteristics compared to value-based sourcing decision making, we base our approach on the Modern Portfolio Theory. This paper makes two contributions in this context: (1) It provides a conceptual foundation for the application of Modern Portfolio Theory within the scope of global sourcing of software development projects by ITSPs. Therefore, we adapt the Modern Portfolio Theory to ensure an optimal and full allocation of given software development projects to available sites. Our newly formed model considers site/project combinations as risky assets, assumes discrete portfolio shares, and factors in transaction costs as well as dependencies between both projects and sites. (2) It is the first to actually apply Modern Portfolio Theory using a real world business case. Thereby, we illustrate that using our model leads to considerably different project allocations to the available delivery centers of our case company as well as to substantially lower costs of the sourcing portfolio.

PINGO: peer instruction for very large groups

In this research, we introduce a new web-based solution that enables the transfer of the widely established Peer Instruction method to lectures with far more than 100 participants. The proposed solution avoids several existing flaws that hinder the widespread adoption of PI in lectures with larger groups. We test our new solution in a series of lectures with more than 500 participants and evaluate our prototype using the technology acceptance model. The evaluation results as well as qualitative feedback of course participants indicate that our new solution is a useful artifact to transfer the PI method to large groups.

Sophistication Banking als erfolgreiche Strategie im Informationszeitalter

Traditionelle Produkt- bzw. Anbietergetriebene Marktbearbeitungsstrategien im Finanzdienstleistungsbereich werden durch die steigende Transparenz, die Veranderung der (Lebens-)Arbeitssituation der interessanten Zielgruppe und die abnehmende und einheitlichere Regulierung nachhaltig nicht mehr profitabel sein. Sophistication Banking als eine Potenzial- und Bedurfnisorientierte Strategie fuhrt zu einer signifikanten Steigerung der Kundenbindung und -loyalitat und letztendlich zu einem steigendem Unternehmenswert. IT-basierte, innovative Multi-Channel/Customer Relationship Ansatze sind dabei fur eine ganzheitliche und kosteneffiziente Betreuung der Kunden unerlasslich.

Enabling eCCRM: content model and management for financial eServices

In the paper a formal content model for the financial services industry as an example of one of the most important eServices industries is presented. Generally, a financial services firm can provide its customers with a great variety and quantity of self-produced and externally bought content. However the challenge is to offer information about the proper subject, at the appropriate sophistication level, the right length, at the right time for the customers specific situation. Meta information about the customer as well as about available content may be used to match content with customer problems in order to get proper solutions that satisfy or exceed customer needs. The focus of the paper lies on both the theoretical identification of relevant attributes to formally describe finance related content and on an implementation concept. Some implementation issues are also discussed in the context of an ongoing project with Deutsche Bank.

Beating Irrationality: Does Delegating to IT Alleviate the Sunk Cost Effect?

We investigate the impact of delegating decision making to information technology IT on an important human decision bias-the sunk cost effect. To address our research question, we use a unique data set containing actual market transaction data for approximately 7,000 pay-per-bid auctions. In contrast with the laboratory experiments of previous related studies, our research presents the unique advantage of investigating the effects of IT-enabled automated bidding agents on the occurrence of a decision bias in real market transactions. We identify normatively irrational decision scenarios and analyze consumer behavior in these situations. Our findings show that participants with a higher behavioral investment are more likely to violate the assumption of normative economic rationality because of the sunk cost effect. More importantly, we observe that the delegation of auction participation, i.e., actual bidding, to IT significantly reduces the occurrence of the sunk cost effect in subsequent decisions made by the same individual. We can attribute this reduction to the comparably lower behavioral investments incurred by auction participants who delegate their bidding to IT. In particular, by mitigating different contributors of behavioral investments, delegating to IT reduces the likelihood of the occurrence of the sunk cost effect by more than 50%.

Customer portfolio management in e‐commerce: an analytical model for optimization

Purpose – The purpose of this paper is to present a model that retailers engaged in e‐commerce (e‐tailers) can use for determining the optimal mix of customer segments within a customer portfolio from an integrated risk and return perspective.Design/methodology/approach – Portfolio Selection Theory of Markowitz is applied to find the optimal composition of customer portfolios. The model is developed and discussed for two customer segments (relationship‐ and transaction‐oriented customers) and exemplarily applied to a data set of an e‐tailer.Findings – Portfolio Selection Theory of Markowitz is well‐suited and promising for determining an optimal customer portfolio from a risk‐return perspective. However, since customers vary from financial assets in several aspects, the results of the model have to be interpreted conscientiously and the resulting action options have to be interpreted within the context of customer relationship management (CRM).Research limitations/implications – The model proposes to carr...

A User-Driven SOA for Financial Market Data Analysis

This paper is concerned with an environment, referred to as Ad-hoc DAta Grid Environment (ADAGE), which facilitates the analysis of large financial datasets by expert end-users. The paper focuses on the design of a Service-Oriented Architecture (SOA) that makes it possible to define re-usable and interoperable software components as web services to manipulate entities of an underlying event-based data model. Such a model allows for a coherent representation of market activities as events, e.g., high-frequency market data like trade prices and quotes, and a subsequent analysis. The paper also describes an implementation of a user-driven composition tool based on the SOA which allows domain experts to conveniently compose services to execute individualised processes. The approach is illustrated on a case study about analysing the price setting behaviour of issuers in the market for structured products.
