Are Two Better than One?

Das Konzept der Hybriden Intelligenz gewinnt zunehmend an Popularität (Horvitz 2014). Dieses Konzept zielt darauf ab, die komplementären Stärken von menschlicher Intelligenz und KI zu nutzen, um sich intelligenter zu verhalten, als es jede der beiden für sich genommen sein könnte (Kamar 2016). Die Integration von menschlichem Input in die künstliche Intelligenz bringt jedoch Herausforderungen mit sich, da insbesondere die menschliche Intelligenz nur dann integriert werden kann, wenn bestimmte organisatorische Randbedingungen adäquat berücksichtigt werden (Kamar 2016). Im Rahmen des vorliegenden Grundlagenforschungsfondsprojekts wird daher untersucht welche Auswirkungen der Einsatz hybrider Intelligenz auf die Performanz sozio-technischer Systeme hat.

Design Principles for Service Systems in the Internet of Things

The Internet of Things (IoT)–understood as digitizing and connecting the physical world and its objects–uses a multitude of technologies to bring along many technical advancements. Overall, IoT is expected to have tremendous economic impact in the nearer future and to affect all sectors and settings of our business and private lives, e.g. in manufacturing, smart cities, healthcare, etc. Thereby, the value IoT systems can deliver depends on the services they can offer to users and customers. To leverage the potentials of IoT and its technical feasibility and superiority, not only the purely technological connectedness of things, but also the interplay and design of interfaces between IoT and people are crucial, i.e. people, software and hardware need to be orchestrated.To realize this interplay between IoT hardware, IoT software and people, all need to be integrated into existing value networks, e.g. patients and physicians need to be an integral part when designing IoT systems for medication adherence. While current research mainly focuses on empirically analyzing IoT systems and its effects, research concentrating on design knowledge for IoT systems is missing. The project wants to close this research gap and extend the existing body of knowledge by generating design knowledge for this highly promising area. To describe the involved stakeholders and technologies of IoT systems, the concept of service systems is used and a sociotechnical system’s perspective is taken. Service systems are defined as value-co-creation configurations of people, technology and value propositions, e.g. patients and their relatives, physicians and care personnel as the involved “people” who are “co-creating value” by working together to improve the patient’s quality of life while using “technology” such as IoT devices or infrastructures.

Enhancing Student Performance Through Formative Feedback in Large Scale University Lectures (SNF Doc Mobility)

In einer 10. Klasse des Gymnasiums und einer Berufsschulklasse bearbeitete eine Gruppe die Aufgaben mit Hilfe eines Smart Personal Assistants, die andere Gruppe mit “traditionellen” Methoden. Die empirischen Ergebnisse zeigten, dass die Schüler in den Experimentierklassen signifikant mehr Problemlösungskompetenzen erwarben als die Schüler in den Kontrollklassen und sich die Lernprozesse veränderten. Die Ergebnisse liefern erste empirische Belege für den Wert des Einsatzes von Smart Personal Assistants wie z.B. Alexa auf die Fähigkeiten zum Lösen von Problemen.

IS Architecture

This project investigates IS architecture from two distinctive, but interrelated perspectives. While the first part of the project employs a static approach to explain which institutional factors underlie desirable outcomes for IS architecture, the second part opts for a dynamic approach to explain how IS architecture evolves over time. This project combines both static and dynamic explanations to triangulate the generated theories on IS architecture.

An unhealthy lifestyle is one of the key factors of mortality in modern society. Persuasive technologies, information systems that aim to change users behaviors and attitudes in a predefined way, are increasingly used for health promotion to encourage a physically active lifestyle and healthful nutrition to prevent diseases of affluence. Persuasive technologies for health come in different shapes, though, recent advances in mobile and sensor technologies have given rise to wearable self-tracking devices that have shortly reached high penetration in mainstream markets. While high hopes lie on persuasive technologies to improve personal and public health outcomes and empirical evidence for their effectiveness exists, concerns regarding their capacity to sustainably induce changes in health behaviors are growing. Despite the rich body of literature on the adoption of persuasive technology, gaps in knowledge exist with regard to users post-adoptive use experiences and behaviors, the processes along which persuasive technologies generate cognitive-affective and behavioral outcomes, and how persuasive technologies can impel such processes in a targeted way. This cumulative dissertation addresses these gaps and seeks to gain an understanding of post-adoptive use processes, to explain the occurrence of adverse experiences and their effects on users, to explain the outcomes of persuasive technology use, and to generate design knowledge to develop persuasive technologies to achieve long-term changes in health-promoting behaviors. These research objectives are achieved through eight research papers using different research approaches to shed light at different aspects concerning the post-adoptive use, the behavioral outcomes, and the design of persuasive technologies, by applying qualitative and quantitative research methods, and following the design science research paradigm. The dissertation makes several primary contributions to persuasive technology research: First, users habit formation processes and adverse experiences are highlighted. Second, the outcomes of persuasive technology use are outlined and mechanism-level explanations for why some users arrive at behavioral outcomes while others do not are provided. Third, by presenting a design artifact, design knowledge for the development of adaptive persuasive technologies for health promotion is generated. Moreover, the findings have important implications for practitioners, in particular, providers of persuasive technology and system designers.

Currently, more and more learning environments exist in whole or in part online. Although these learning environments can be scaled to large audiences, the lack of interaction between educators and students is difficult to replace and remains a primary challenge in the field. This is why Smart Personal Assistant Technology (SPAT) has received attention in the field. SPAT describes computer systems intended to converse with humans. These systems may alleviate the problem of individual support in online and blended learning environments by engaging in natural interaction with the students. Although SPAT seems to be promising for education, three important challenges related to SPAT design emerge and will be tackled in this dissertation. Research Challenge (RC) 1: There is limited knowledge about existing SPAT and corresponding requirements of SPAT in online and blended learning environments. RC2: There is limited knowledge of how to design SPAT to improve students learning outcomes. RC3: It is not yet clear how non-tech-savvy educators can design and use SPAT on their own to offer individual support. This dissertation tackles these RCs by following a multi-method approach that identifies research gaps and requirements of SPAT in online and blended learn-ing environments in order to propose design principles (DPs) and design knowledge regarding how educators can use the technology. The dissertation has three main core findings. First, the findings show that there is a lack of consensus on how to design and develop SPAT for online and blended learning environments. Second, based on the first finding, this study proposes five DPs on how to design SPAT in these contexts and investigate the effectiveness of these principles in a series of laboratory and field experiments across different school levels (secondary education, higher education) and school types (high school, vocational business school, university). The findings show that these DPs can have a positive influence on students learning processes resulting in increased students learning outcomes. It also addresses the third RC by developing a SPAT Platform that empowers non-tech-savvy educators to create their own SPAT in order to make this technology accessible to educators who are not technically inclined. The dissertation contributes to a theory of design and action that explains how non-tech-savvy educators can design effective SPAT in their online and blended learning environments.

While digital transformation as a research phenomenon per se gains acceptance in both practice and academia, its precise conceptualization and theoretical underpinnings are discussed. To address these gaps, we propose a critical realist view on Digital Transformation. Building on a literature review on generative mechanisms in digital transformation studies, we show how the concept of generative mechanisms is used and what types of generative mechanisms are adopted. Based on our findings, we propose a research agenda that encourages further studies on digital transformation, taking a critical realist stance. Thus, we put forward ways of applying critical realism to digital transformation studies and show how critical realism can advance research through its ability for multi-level analysis and its unique understanding of change and transformation.

Digital nudging is a promising approach from behavioral economics. In deci-sions where individuals tend to struggle, nudges can support users of digital systems by aligning their behavior with their preferences. Despite their wide use, most digital nudges are designed to support the intended behavior from the perspective of a company while neglecting potential legal, ethical, or individual constraints or preferences. With modern technologies such as artificial intelli-gence or big data, these issues multiply and with the increasing effectiveness of digital nudges and use of new technologies, this has become even more critical. Thus, in this paper we follow a Design Science Research approach to develop a process model for the systematic development of legitimate nudges (DELEN). Legitimacy requires that dealings between different entities shall be fair. Unlike other models, we set normative boundaries derived from literature, expert in-terviews, and target group segmentation as integral elements. Target group seg-mentation increases nudge effectiveness and avoids unnecessary burdens for other individuals. By doing so, the DELEN process model paves the way for legitimate and effective digital nudges.

Volatility, uncertainty, ambiguity, and complexity (VUCA) are drivers in today’s business world. Therefore, an increasing number of organizations implement agility (agile methods) to cope with the rapid and accelerating change. However, these agile transformations do not succeed unhindered, and some fail. One reason for that is the employees lacking an agile mindset and they do not support or participate in the transformation. So far, knowledge of the agile mindset is in its infancy. A conceptualization for developing a measuring instrument on the individual level is lacking. Furthermore, the relevance of the agile mindset regarding organizational performance in a VUCA world is still unclear. Our study aims to close this gap. To do so, we examine the agile mindset with 15 qualitative interviews and conduct an online survey (N=449) to predict organizational agility and organizational performance based on the agile mindset. As for results, we conceptualize the agile mindset as an attitude that comprises four dimensions: ’learning spirit’, ‘collaborative exchange’, ‘empowered self-guiding’, and ‘iterative value creation’. We have found an indirect effect of the agile mindset affecting organizational performance towards organizational agility. These findings contribute to the agility and management research by providing both a conceptualization and a measuring instrument for the agile mindset. Furthermore, the agile mindset´s relevance in agile transformation is explained and its relation to organizational performance outlined. For successful agile transformation, executives must focus on the agile mindset of their employees and foster this by e.g. being a role model.

We present an annotation approach to capturing emotional and cognitive empathy in student-written peer reviews on business models in German. We propose an annotation scheme that allows us to model emotional and cognitive empathy scores based on three types of review components. Also, we conducted an annotation study with three annotators based on 92 student essays to evaluate our annotation scheme. The obtained inter-rater agreement of α = 0.79 for the components and the π = 0.41 for the empathy scores indicate that the proposed annotation scheme successfully guides annotators to a substantial to moderate agreement. Moreover, we trained predictive models to detect the annotated empathy structures and embedded them in an adaptive writing support system for students to receive individual empathy feedback independent of an instructor, time, and location. We evaluated our tool in a peer learning exercise with 58 students and found promising results for perceived empathy skill learning, perceived feedback accuracy, and intention to use. Finally, we present our freely available corpus of 500 empathy-annotated, student-written peer reviews on business models and our annotation guidelines to encourage future research on the design and development of empathy support systems.

Business ecosystems are dynamic network structures of autonomous actors who contribute individual resources and capabilities towards a shared purpose. This study proposes a design theory to develop a model that describes the fundamental value creation activities in business ecosystems. This research endeavor is embedded in a consortium research project following design science and builds on both the current body of academic knowledge and the experience of. The paper makes three main contributions. Firstly, the study defines a specific problem space, identifies justificatory knowledge, and develops design requirements and principles as the theory’s core. Secondly, a reference model is developed that describes value creation, providing a conceptual grid for further theoretical analysis. Thirdly, the model provides an analytical framework for practitioners, who need to understand which activities should be performed and how these activates should be configured to generate advantages relative to others.

Im Rahmen einer Lehrveranstaltung des Masters in Business Innovation im Frühjahr 2021 gelang es, ohne vertiefte Kenntnisse der Bäckereibranche durch Verwendung bereits vorhandener Daten und durch Nutzung von Methoden der Statistik und der Künstlichen Intelligenz die Verkaufsprognosen der Filialleiterinnen und Filialleiter zu übertreffen und die Verkäufe des folgenden Tags mit einer Abweichung von ca. 13% bis 14% vorherzusagen. Diese unerwartet guten Ergebnisse lassen den Schluss zu, dass der Einsatz von Methoden der Statistik und der Künstlicher Intelligenz auch in KMUs wie Bäckereien in Zukunft wettbewerbsrelevant sein wird. Wenn es gelänge, die Prognosequalität zu verbessern, wäre in Bäckereien Nutzen in zwei Richtungen zu erwarten: Der unternehmerische Erfolg kann gesteigert und der Foodwaste reduziert werden. Allerdings bräuchte es mehr und bessere Daten, weiteren Austausch mit Experten der Domäne sowie geeignete Apps, um datengetriebene Prognosen in den Bäckereien zu implementieren.

    Dominik Gutt,  Assistant Professor at Rotterdam School of Management: The Rise of Robo-Reviews – The Effects of Chatbot-Mediated Review Elicitation on Online Reviews

    Chatbots have been introduced as a new way to receive product reviews. However, little is known how the chatbot-mediated solicitation influences review characteristics such as the valence or the helpfulness. We conduct four studies to narrow this literature gap. Our results show that (1) chatbot-mediated review elicitation leads to a positivity bias in ratings, particularly strong for low-quality products; (2) chatbot-mediated reviews negatively impact a range of review dimensions (e.g., helpfulness) mainly due to decreased review length, (3) the positivity bias varies depending on the level of anthropomorphism in the chatbot and the nature of the survey deployer (seller vs. platform), and can be explained by audience tuning due to social presence. Our research is among the first to uncover a link between chatbot use, review valence, and other valuable review

    Prof. Dr. Ali Sunyaev, Karlsruher Instituts für Technologie (KIT): Design Trade-Offs, Viability, and Management of Applications on Distributed Ledger Technology

    While design decisions determine the quality and viability of applications in general, in Distributed Ledger Technology (DLT), the decision for a suitable DLT design (e.g., Ethereum, IOTA) is of particular relevance because the retroactive change of the underlying DLT design is currently very hard and often even impossible. Extant research has revealed several trade-offs between DLT characteristics (e.g., availability vs. consistency). Such trade-offs inhibit a one-size-fits-all DLT design that suites the requirements of applications on DLT. For an appropriate assessment of the suitability of DLT designs for a particular application on DLT, researchers and developers require a systematic and holistic overview of the functioning of different DLT designs, including their configuration of DLT characteristics as well as dependencies and resulting trade-offs between DLT characteristics. In this talk I will first summarize and reflect the design trade-offs, viability, and management of applications on DLT. Second, I will present the configuration and management tool for applications on DLT we currently work on.

    Dr. Monika Malinova Mandelburger, WU Wien; “Cognitive diagram understanding and task performance in systems analysis and design”

    Diagrams play an important role in Systems Analysis and Design (SAD). So far, cognitive research on diagram criteria in relation to task performance has been fragmented. The aim of this talk is to (1) discuss the cognitive processing steps involved during understanding and task performance with diagrams, (2) discuss criteria for such diagrams to best support cognitive processing and (3) demonstrate the support effective diagrams provide for performing SAD tasks. First, we present a theoretical cognitive framework of task performance with diagrams called CogniDia. It integrates different cognitive theories from research on diagrams in software engineering and information systems. Second, we present findings from a literature review on criteria for effective cognitive processing of diagrams. Third, we use the theoretical cognitive framework CogniDia to investigate how diagrams support the SAD process effectively.

    Monika Malinova is a postdoctoral researcher with the Institute for Information Business at the Vienna University of Economics and Business (WU Vienna), Austria. She obtained her PhD degree in 2016 from WU Vienna.

    Research Talk Henderik Proper: Fundamental challenges in systems modelling

    26. September 2019

    Standort: Institut für Wirtschaftsinformtik, St. Gallen

    Prof. Henderik Proper, Luxemburg Institute of Science and Technology (LIST); Fundamental challenges in systems modelling

    Abstract: In the context of information systems, and digital ecosystems at large, many different forms of systems modelling are used. This includes: enterprise (architecture) modelling, business process modelling, ontology modelling and information modelling. The resulting models have come to play an important role during all stages of the life-cycle of digital (eco)systems.

    In our view, the key role of models also fuels the need for a more fundamental reflection on core aspects of modelling itself. In line with this, the goal of this presentation is to explore some of the underlying fundamental challenges of modelling, and in doing so create awareness for, and initiate discussions on, the need for more foundational research into these challenges.

    The discussion of these challenges has been structured in terms of three clusters: the semiotic foundations, the essence of modelling, and the role of normative frames (such as modelling languages).

    Research Talk Sunil Wattal: Competitive Poaching in Search Advertising: A Randomized Field Experiment

    16. July 2019

    Standort:

    Prof. Sunil Wattal, Assistociate Professor at Fox School of Business, Temple University, Philadelphia; “Competitive Poaching in Search Advertising: A Randomized Field Experiment”

    Abstract: Keyword searches with brand names occur very commonly on search engines, which enables firms to infer not only when customers are searching for them, but also when customers are searching for their competitors. In other words, firms can generate traffic from search engine advertising by bidding not only on their own keywords but also on competitors’ keywords. The strategy of bidding on competitors’ keywords, known as competitive poaching, presents unique opportunities for academic research.

    In this research, we examine the factors that influence the effectiveness of competitive poaching, specifically the role of different ad copies and the type of competitor (poached brand) that a brand is “poaching” from. We also examine how competing sponsored ads from the poached brand and other advertisers have an impact on competitive poaching. We run a field experiment for a three-month period with a business school in northeastern United States, by bidding on keywords of competing schools and randomly displaying different types of ad copies. We find that ad copies that feature vertical differentiation are more effective than other ad copies when poaching on keywords of high-quality brands. We also find that when poaching from low-quality brands, ad copies featuring horizontal differentiation perform better than other ad copies. We further show that the presence of the poached brand’s own ad leads to a positive impact when that brand is high-quality, and a negative impact if the poached brand is low-quality. Finally, we also find that the presence of other advertisers using quality signals in their ad copies has a positive impact on clicks. However, use of vertical differentiation ad copies by the focal brand negatively moderates the impact of  the presence of other advertisers using quality signals. The academic and managerial contributions are also discussed.
