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.

Driven by circumstances like the global pandemic many learners and educators realize the importance and value of self-regulated digital learning. To better support self-regulated learning, conversational agents have become more relevant. Conversational agents can act as tutor or as learning mate for learners. Although conversational agents have potential to better support self-regulated learning processes, challenges exist requiring implications about how to make these interactions more engaging and supportive. This study discusses the value of gamified conversational learning chatbots that use game elements to engage learners to guide researchers and practitioners to design conversational agents that effectively motivate learners and provide self-regulated learning at the same time. Therefore, we propose a systematically developed framework for gamifying educational conversational agents and contribute to theory by consolidating several theories about games, digital learning, and conversational agents and support practitioners by providing implications about what to care about when gamifying conversational agents

Today’s servitized and digitalized society has significant implications for the economic system as value creation increasingly shifts towards digital services. Organizations are increasingly relying of artificial intelligence, which enables them to operate with novel technological artifacts like conversational agents (CA). These human-like AI-driven artifacts open new possibilities and channels for service providers to scale up their business even further and to create a business value or even to make processes more efficient. While we witness the results of that each day, we do not fully understand how such CAs can contribute to scaling up a business. Therefore, we conduct an analysis of service research and popular CAs to determine the status quo and highlight opportunities for scaling services with CAs. We contribute to theory by clarifying the meaning of scalability in combination with CAs and support practitioners by providing an overview about how organizations successfully scale their CAs.

The increasing digitalization and automatization in the manufacturing industry as well as the need to learn on the job has reinforced the need for much more granular learning, which has not yet impacted the design of learning materials. In this regard, granular learning concepts require situated learning materials to support self-directed learning in the workplace in a targeted manner. Co-creation approaches offer promising opportunities to support employees in the independent design of such situated learning materials. Using an action-design research (ADR) approach, we derived requirements from co-creation concepts and practice by conducting focus group workshops in manufacturing and vocational training schools to develop design principles for a co-creation system that supports employees through the creation process of work-process-related learning material. Consequently, we formulate four design principles for the design of a collaborative learning and qualification system for manufacturing. Using an innovative mixed methods approach, we validate these design principles and design features to demonstrate the success of the developed artifact. The results provide insights regarding the design of a co-creation system to support learners in the co-creation of learning material with the consideration of cognitive load (CL). Our study contributes to research and practice by proposing novel design principles for supporting employees in peer creation processes. Furthermore, our study reveals how co-creation systems can support the collaborative development of learning materials in the work process.

Design science projects are of great interest in information systems (IS) research. Typically, design-oriented projects generate valuable design knowledge through the design and possible instantiation of artifacts. Although designing novel artifacts and accumulating design knowledge is common practice in IS, there is still limited shared knowledge about the distinctive characteristics of design knowledge to facilitate its accumulation. To address this issue, we develop a design knowledge taxonomy and contribute to a deeper understanding of design knowledge properties. The taxonomy is grounded on a systematic literature review, followed by a combination of empirical-to-conceptual and conceptual-to-empirical iterations. We evaluate the taxonomy by interviewing six domain experts and demonstrate its practical application and utility. Thus, the taxonomy consists of key dimensions and characteristics of design knowledge and contributes to a better scientific understanding of its characteristics. Practitioners can use the taxonomy as an instrument to further understand, design, and accumulate design knowledge.

To ensure that an intended target group accepts and uses an information system (IS) is a major challenge for service systems engineering and a key interest in IS research. On the one hand, individuals’ cultural values affect their willingness to use an IS; on the other hand, information technology (IT) is neither value-neutral and, thus, also affects IT acceptance and usage. Therefore, the adaptation of IS should consider both sources of value. Thus, in this paper, we present the theory-driven design of a method for culture-sensitive IS adaptation that draws on IT-culture conflict theory. Our two-fold evaluation approach results show that the method enables to create feasible results for developing culture-sensitive design solutions for IS. As a theoretical contribution, we contribute to the exploration of culture in IS development; as a practical contribution, we provide guidance in how to adapt IS for specific target groups.

As more and more organizations reach the limits of their internal capabilities to deal with the challenges induced by digital transformation, they are increasingly forced to seek external digitalization opportunities. In particular, small and medium enterprises are affected by this due to their limited human and financial resources. Currently, there is a lack of overview of options considering limited internal digital capabilities and resources. Thus, we choose an action design research approach to develop an external digitalization activity navigator. As a result, we derive five design principles for successful navigation and 30 activities, which are presented as design pattern cards. Our work can help practitioners and scholars alike to structure external digitalization activities. After discussing the insights, we outline directions for future research. We conclude by noting the managerial implications of our findings.

Although the nexus of Design Thinking (DT) and corporate entrepreneurship is heralded to be promising, the concrete compositional architecture of how DT manifests in practice has received limited scholarly attention. Drawing on the argument that DT can facilitate intrapreneurial innovation as it enables effectual cognition, we developed a multidimensional assessment model that measures DT for intrapreneurial innovation in an organizational context and applied it via an online survey to 547 organizations of different sizes and industries. An analysis of the dimensional and sub-dimensional values obtained from the quantitative survey data in general, and with regard to industry and firm size types in detail, enriches our understanding of DT’s manifestation in practice. We provide practitioners a useful tool to assess, benchmark, plan, analyze, and communicate the use of DT for intrapreneurial innovation, and guide future DT and entrepreneurship researchers seeking practitioner-relevant insights with nine propositions derived from our observations.

To equip students with practical capability to innovate, academic institutions are promoting industry collaboration projects where students use creative approaches, for example, design thinking, to solve complex business challenges. In creative work, the ability to reflect on the current team state and to continuously improve based on these insights is vital for effective teams. However, research on the role of digital technology to support collaborative reflection is still in its infancy. This study aims to present a digital solution that uses micro surveys and concepts of Educational Data Mining (EDM) to support collaborative reflection of students working in creativity-driven engineering projects. Using design science research, we identify design requirements of the InnoPulse tool, implement the corresponding design features and evaluate our digital solution in a real-world educational setting. Our findings pave the way for the potential of using EDM concepts to improve collaborative reflection of students using DT methods.

Intelligent agents (IAs) are permeating both business and society. However, interacting with IAs poses challenges moving beyond technological limitations towards the human-computer interface. Thus, the knowledgebase related to interaction with IAs has grown exponentially but remains segregated and impedes the advancement of the field. Therefore, we conduct a systematic literature review to integrate empirical knowledge on user interaction with IAs. This is the first paper to examine 107 Information Systems and Human-Computer Interaction papers and identified 389 relationships between design elements and user acceptance of IAs. Along the independent and dependent variables of these relationships, we span a research space model encompassing empirical research on designing for IA user acceptance. Further we contribute to theory, by presenting a research agenda along the dimensions of the research space, which shall be useful to both researchers and practitioners. This complements the past and present knowledge on designing for IA user acceptance with potential pathways into the future of IAs.

Purpose – The emergence of Internet of Things (IoT) platforms in product companies opens up new data-driven business opportunities. This paper looks at the emergence of these IoT platforms from a business-model perspective. Design/methodology/approach – The study applies a mixed method with two research studies: Study I–a cluster analysis based on a quantitative survey, and Study II–case studies based on qualitative interviews. Findings – The findings reveal that there is no gradual shift in a company’s business model, but in fact three distinct and sequential patterns of business model innovations: (1) platform skimming, (2) platform revenue generation and (3) platform orchestration. Research limitations/implications – The results are subject to the typical limitations of both quantitative and qualitative studies. Practical implications – The results provide guidance to managers on how to modify the components of the business model (value proposition, value creation and/or delivery and profit equation) in order to enable platforms to advance. Social implications – As IoT platforms continue to advance, product companies achieve better performance in terms of productivity and profitability, and more easily secure competitive advantages and jobs. Originality/value – The paper makes three original contributions: (1) it is the first quantitative study on IoT platforms in product companies, (2) identifies three patterns of business model innovations and (3) offers a first process perspective for understanding the sequence of these patterns as IoT platforms advance.

    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.
