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.

With the advent of artificial intelligence (AI), individuals are increasingly teaming up with AI-based systems to enhance their creative collaborative performance. When working with AI-based systems, several aspects of team dynamics need to be considered, which raises the question how humans’ approach and perceive their new teammates. In an experimental setting, we investigate the influence of social presence in a group ideation process with an AI-based teammate and examine its effects on the motivation to contribute. Our results show a multi-mediation model in which social presence indirectly influences whether human team members are motivated to contribute to a team with AI-based teammates, which is mediated by willingness to depend and team-oriented commitment.

To face the challenge of digital transformation as well as to implement digital innovation many incumbent companies have set up digital innovation units (DIUs). Despite a steadily growing body of knowledge, there is a rather static picture of DIUs in the literature to date, and we have little knowledge of how these units evolve over time to continuously contribute to digital transformation and innovation. To lay the foundation for an understanding of DIUs as dynamically evolving entities, we conduct a multiple-case study with DIUs of five manufacturing companies and identify DIU evolution as a process driven by an interplay of life-cycle and dialectic motor of change. In the course of this, we also outline specific triggers, sequences, and the nature of change. We generalize our findings with a conceptual process model of DIU evolution and three propositions on their current and future development to inform the existing and forthcoming literature.

While information systems development (ISD) projects play a pivotal role in maintaining a competitive advantage, ISD project distress evolves dramatically. Given the complex and dynamic nature of ISD projects, they are prone to Escalation of Commitment (EoC), the irrational tendency to persist with failing courses of action. While EoC has been studied to a great extent in management and psychology literature, research on its role in the context of ISD project distress is fragmented, making it challenging to develop de-escalation strategies. To address this gap, we conduct a literature review on EoC in the context of ISD project distress. The proposed nomological net including triggering factors, consequences, mediators, and moderators, as well as a set of developed de-escalation strategies can serve as an inspiration and foundation for future IS researchers. By presenting this review we hope to inform future IS research to acknowledge the role of EoC in ISD projects.

Today formal education like higher education relies on digital learning content like learning videos or quizzes. Using such online learning material enables students to learn independently from time and place. While improvements have been made, there are still many issues as the two-year long crisis in 2020 has revealed. Many offerings do not consider the learners’ needs and can result in unsuccessful learning. One way to address these short comings is to actively include learners in the creation process of learning content. However, co-creation oftentimes relies on face to face and or group settings that may not be possible for all students at all times. Therefore, we undertake a long-term action design research project to investigate the novel concept of conversational co-creation of learning material using a conversational agent and persuasive design to engage and motivate learners. In this article we present an early-stage prototype and concept of conversational co-creation.

Crises become the norm for organizations, as recent years have shown. Especially the automotive industry is still facing disruptive changes such as e-mobility, connected cars or autonomous driving. Disrupted supply chains, related production downtimes and associated financial losses are consequences. Procurement departments are the interface between internal and external stakeholders in supply chains, and therefore, the central authority for managing crises. In such situations, effective decision-making is essential. Positive effects of data analytics on decision-making were part of numerous research endeavors, as well as related data analytics competencies. We conducted semi-structured interviews with experienced experts about relevant data analytics competencies in procurement departments. We present an overview specifically for procurement departments and derive implications of these competencies on decision-making. As a result, we apply our findings to existing research from a theoretical perspective and support procurement leaders and their departments in facing current and future challenges from a practical perspective.

Although conversational agents (CA) are increasingly used for providing purchase recommendations, important design questions remain. Across two experiments we examine with a novel fluency mechanism how recommendation modality (speech vs. text) shapes recommendation evaluation (persuasiveness and risk), the intention to follow the recommendation, and how modality interacts with the style of recommendation explanation (verbal vs. numerical). Findings provide robust evidence that text-based CAs outperform speech-based CAs in terms of processing fluency and consumer responses. They show that numerical explanations increase processing fluency and purchase intention of both recommendation modalities. The results underline the importance of processing fluency for the decision to follow a recommendation and highlight that processing fluency can be actively shaped through design decisions in terms of implementing the right modality and aligning it with the optimal explanation style. For practice, we offer actionable implications on how to make effective sales agents out of CAs.

The centrality of information systems (IS) customization to match companies' needs with software systems available in the market has been researched extensively. The distinctive characteristics of Artificial Intelligence (AI) systems compared to other types of IS suggest that customization needs a new conceptualization in this context. We draw on evidence from expert interviews to conceptualize customization of AI systems as composed of four layers: data, models, algorithms, infrastructures. We identify a continuum of levels of customization, from no to complete customization. Since companies customize AI systems in response to business needs, we develop a theoretical model with six antecedents of AI systems' customization choices. In so doing, we contribute to both AI management research, by introducing the IS customization perspective in the field, and IS customization literature, by introducing AI systems as a novel class of systems and enlarging the understanding of customization for a specific class of software systems.

    Research Talk Dr. Maximilian Schreieck, Ass. Prof. for Information Systems, University of Innsbruck, on “Digital Platform Strategies: The Role of The Digital Upper Echelons”

    11. January 2023

    Standort: IWI-HSG, Müller-Friedbergstrasse 8, 9000 St.Gallen (Raum 52-6120) oder per Zoom

    Datum: 11.01.2023, 14:15 bis 15:30

    Abstract: We examine how a company’s digital upper echelons—the members of the top management team with IT-related responsibilities as their primary role—impact the success of digital platform strategies. Focusing on the S&P1500 companies, we show that an initial negative effect of digital platform strategies on a company’s growth opportunities becomes positive after a lag of six years. We find that this positive effect only holds for companies that implement the digital platform organically (“build strategy”) and not for companies that acquire a digital platform (“buy strategy”). Second, we examine the moderating effect of the maturity of digital upper echelon positions. We analyze whether emergent digital upper echelon positions, such as chief digital officers (CDOs) or established digital upper echelon positions, such as chief information and chief technology officers (CIOs, CTOs), have a greater influence on a digital platform strategy’s success. While we do not find a clear positive moderating effect for either position, a post-hoc test reveals that the presence of a CDO has a positive moderating effect for the build strategy but a partially negative effect for the buy strategy. Our findings contribute to understanding why some companies are successful with digital platform strategies while others are not.

    Research Talk Dr. Andreas Hein, Postdoc, Krcmar Lab, Technical University of Munich (TUM): “We Reap What We Sow: How CIOs Change the Outcome of Organizational Crisis”

    1. December 2022

    Standort: IWI-HSG, Müller-Friedbergstrasse 8, 9000 St.Gallen (Raum 52-7024) oder per Zoom

    Datum: 01.12.2022, 14:15 bis 15:30

    Abstract: Pandemics, global warming, and war, whether physical or digital, are grand challenges of our age. Based on a more and more globalized and interconnected world, those challenges’ severity and frequency are increasing (see Global Risk Report by the World Economic Forum). Therefore, managing crises and making organizations resilient become vital capabilities of the top management team (TMT). As the TMT approaches those challenges, the Chief Information Officer (CIO) often emerges as the actor who holds the keys to making the firm more resilient. For example, CIOs triggered the virtualization of workspaces and the provision of hardware such as smartphones and laptops, which later became the essential factors helping the Chief Executive Officer transition the operational mode from physical to digital during COVID-19. However, despite the rising importance, we know little about how TMTs, in general, and the CIO, in particular, make firms more resilient in responding to the grand challenges of our age. Our study builds on the theory of crisis management and organizational resilience to explain how CIOs built proactive resilience before the crisis and utilized this during crisis management as reactive resilience to steer the outcome trajectory of the crisis. The process model illustrates how capacities, authority, and the mitigation of fragilities before a crisis impact the cognitive and behavioral response, which determines if firms suffer adverse effects, can retain the status quo, or even thrive in the advent of an emerging crisis.

    Research Talk Prof. Dr. Kai Spohrer, Associate Professor of Information Systems, Frankfurt School of Finance & Management: “And No One Gets the Short End of the Stick: A Blockchain-Based Approach to Solving the Two-Sided Opportunism Problem in Inter-Organizational Information Sharing”

    14. November 2022

    Standort: IWI-HSG, Müller-Friedbergstrasse 8, 9000 St.Gallen (Raum 52-7024) oder per Zoom

    Datum: 14.11.2022, 14:15 bis 15:30

    Prof. Dr. Kai Spohrer, Associate Professor of Information Systems, Frankfurt School of Finance & Management: “And No One Gets the Short End of the Stick: A Blockchain-Based Approach to Solving the Two-Sided Opportunism Problem in Inter-Organizational Information Sharing”

    The threat of opportunistic behavior is an enduring problem for inter-organizational information sharing. The two sides of opportunism in inter-organizational information sharing – information poaching by the information recipient and information manipulation by the information provider – cause high transaction costs and sometimes preclude information sharing relationships altogether. Existing organizational and technological countermeasures against the two-sided threat of opportunism can either not reliably preclude information poaching and manipulation or address only one of them at a time. We develop four design principles for a blockchain-based system that permits information sharing based on sensitive data in inter-organizational business transactions without revealing the actual data. Thus, our solution simultaneously precludes both information poaching and information manipulation, enabling a novel class of information sharing. We instantiate our design principles in a prototype within a multi-firm research consortium for wear-based leasing contracts for machine tools. An evaluation shows that organizations are willing to engage in more inter-organizational information sharing and draw on more sensitive data when using the proposed prototype compared to traditional inter-organizational information systems. Our study contributes to research on opportunism in inter-organizational information sharing and confidentiality in blockchain networks.

    Kai Spohrer is Associate Professor of Information Systems with the Frankfurt School of Finance & Management. In his research, he applies qualitative and quantitative methods as well as design science to understand and shape the development and use of information systems. He is particularly interested in questions related to collaboration and coordination in information systems development, IT healthcare, and blockchain systems.

    Digital transformations force organizations to develop and maintain innovative digital products and services. Thus, effectively managing these activities and supporting them with appropriate technology at various levels is crucial for organizational success. To support these goals, Kai Spohrer conducts research at several levels, ranging from psychological explanations of biased behavior in AI system users over team-level analyses of software development methods to investigations into the interactions of software architecture and organizational structure in development organizations. His research has appeared and is forthcoming in Information Systems Research, Journal of Management Information Systems, IEEE Transactions of Software Engineering, and others.

    Prior to joining Frankfurt School, Kai Spohrer was Assistant Professor at the Business School of the University of Mannheim where he completed his habilitation on digital innovation in healthcare and the software industry, focusing particularly on agile development, design, and use of information systems. He received his Ph.D. from the University of Mannheim for his dissertation on collaborative quality assurance and team cognition in software development teams. Over the years, he has spent time as a student and visiting researcher at institutions such as the University of Arkansas, Washington State University, and Universidad Politécnica de Madrid. He is a founding member and the director of content and media of the AIS special interest group “Advances in Sourcing”.

    Abstract: Although conversational agents (CAs) are increasingly used for providing purchase recommendations, important design questions remain. Our research project seeks to examine whether processing fluency is a novel mechanism to explain how recommendation modality (speech vs. text) shapes recommendation evaluations, the intention to follow the recommendation, and how modality interacts with the style of recommendation presentation. Our main goal is to identify under which conditions a specific modality (speech-based or text-based CAs) is superior in terms of processing fluency and consumer responses. Our first research findings provide robust evidence that text-based CAs outperform speech-based CAs in terms of processing fluency and consumer responses. Moreover, the findings underline the importance of processing fluency for the decision to follow a recommendation and highlight that processing fluency can be actively shaped through design decisions in terms of implementing the right modality and aligning it with the optimal recommendation presentation. For example, numerical explanations increase processing fluency and purchase intention of both recommendation modalities. For practice, we offer actionable implications on how to make effective sales agents out of CAs.

    Research Talk Prof. Dr. Simon Trang, Assistant Professor, University of Göttingen: “The technology-behavior compensation effect: How beneficial and actively used technologies can counteract their societal goals”

    18. October 2022

    Standort: IWI-HSG, Müller-Friedbergstrasse 8, 9000 St.Gallen (Raum 52-7024) oder per Zoom

    Datum: 18.10.2022, 14:00 bis 15:15

    Prof. Dr. Simon Trang, Assistant Professor, University of Göttingen: “The technology-behavior compensation effect: How beneficial and actively used technologies can counteract their societal goals”

    In search of solutions to societal health challenges, policymakers are increasingly turning to innovative apps as complements to existing non-technological interventions. Such apps developed for supporting users’ health are designed with the premise of being seen as beneficial and actively used. However, based on risk homeostasis theory, we theorize that these two classical design goals for effective information systems (IS) unintentionally foster risk compensation and lead to the neglection of other non-technical preventive health behaviors. Evidence from a multi-wave study regarding COVID-19 contact tracing apps confirms the existence of what we call the technology-risk compensation effect: those individuals who perceived the app to be highly beneficial or actively use it in return reduce other preventive health behaviors such as social distancing after app adoption. This technology-risk compensation effect implicates a hitherto overlooked tension between two established IS design goals and the successful exploitation of technology to support users’ health. We expand the established perspectives on dark sides of IS use by revealing a previously neglected type of unintended consequences and draw attention to the implications of this finding for research well beyond the health context.

    Prof. Dr. Simon Trang holds the Chair for Information Security and Compliance (‘Juniorprofessur’) at the University of Göttingen. The focus of his work concerns the analysis and effective design of information security measures in companies and for a resilient society. He approaches the topic from a socio-technical perspective, in which information systems and information security are not understood as ends in themselves, but always in the interplay of technology, processes and actors. This includes the study of user behavior and psychology, technical, legal as well as strategic aspects. Prof. Trang and his team have received various grants from renowned public institutions such as the BMBF, the BMWK, the BMG and the Volkswagen Foundation. His work has been published in journals such as the Journal of the Association for Information Systems, the European Journal of Information Systems, and Information Systems Frontiers, among others.

    Research Talk Prof. Dr. Jana-Rebecca Rehse, Universität Mannheim: „User Behavior Mining: Applying Process Mining to Analyze Human Behavior Change“

    19. September 2022

    Standort: IWI-HSG, Müller-Friedbergstrasse 8, 9000 St.Gallen (Raum 52-7024) oder per Zoom

    Datum: 19.09.2022, 11:00 bis 12:30

    Prof. Dr. Jana-Rebecca Rehse, Universität Mannheim: „User Behavior Mining: Applying Process Mining to Analyze Human Behavior Change“

    User behavior mining (UBM) refers to the application of process mining and machine learning techniques to user interaction logs, i.e., high-resolution event logs that record low-level, manual activities performed by a user during the execution of a task in a software system. By analyzing these event logs, UBM can generate detailed insights into how users of a software interact with its user interface. Those insights can be used for technical purposes, such as the mitigation of software usability issues or the automation of process execution. In addition, UBM is a valuable tool for researchers who want to understand or predict a specific aspects of user behavior. It provides a data-driven, non-intrusive method to obtain a holistic view on the behavior of software users over a longer period of time. Researchers can hence use UBM to gather and analyze empirical data, which can be used to test, support, refute, or develop behavioral theories.

    In this talk, I present UBM as an analytical method for examining user behavior in software systems. In the first part, I conceptualize it by means of the four-part UBM framework, which elaborates (1) how UBM data can be captured, (2) which technologies can be applied to analyze it, (3) which objectives UBM can accomplish, and (4) how theories can guide the analytical process. In the second part, I show how we applied UBM to analyze behavior changes in a mobile health (mHealth) scenario. Based on social cognitive theory (SCT), we apply process discovery and sequential rule mining to investigate how people interact with mHealth apps and how these interactions affect their physical activity. We find that by applying UBM, we can empirically substantiate implicit assumptions of SCT and derive recommendations for the optimal design of mHealth apps.

    Research Talk Konstantin Bauman, Ph.D., Ass. Prof. Fox School of Business@Temple University: “Intelligence Augmentation for Higher-Quality Peer Feedback: Supporting Students by Recommending Features of Written Feedback that Should be Improved”

    1. June 2022

    Standort: IWI-HSG, Müller-Friedbergstrasse 8, 9000 St.Gallen (Raum 52-7024) oder per Zoom

    Datum: 01.06.2022, 14:00 bis 15:30

    Konstantin Bauman, Ph.D., Ass. Prof. Fox School of Business@Temple University: “Intelligence Augmentation for Higher-Quality Peer Feedback: Supporting Students by Recommending Features of Written Feedback that Should be Improved”

    The value of peer feedback is growing for large-scale courses in universities, as well as for MOOCs, where it is used as a method to provide students with formative feedback and support them in their learning journey. However, students usually have little to no experience in providing feedback and especially in formulating ideas in a way that would help feedback recipients understand all the raised critical issues and improve their submission accordingly.  In his research talk, Konstantin Bauman will present his work in collaboration with Roman Rietsche, Matthias Söllner and Jan Marco Leimeister from the Institute of Information Management (HSG) and the University of Kassel. In their work they developed an intelligence augmentation approach which was implemented and proposed to support students in the process of creating peer feedback with personalized recommendations of the most critical text features that need improvement. They designed a novel framework that provides such recommendations aiming to maximize the feedback quality as perceived by the feedback recipient. Furthermore, they also designed a novel Feature Utility Saturation Model (FUSM) that works as part of the framework. To test how the proposed method works in practice, they conduct a field experiment with 490 students taking three different courses at a public university in Europe. The results show that the personalized recommendation approach works well as it outperforms baselines and helps students create longer feedback and of significantly higher quality, as evaluated by feedback recipients.

    Dr. Konstantin Bauman joined the Fox School on a tenure track appointment within the Department of Management Information Systems on January 1, 2018. He arrives at Fox from the Stern School of Business at New York University, where he served as a postdoctoral research fellow. Bauman’s research interests lie in the areas of technical information systems, with focus on the fields of quantitative modeling and data science. In particular, he works on developing novel machine learning methods for predicting customer preferences, and designing novel approaches to recommender systems that provide personalized advice to customers. Before joining NYU, Bauman worked as the head of a machine-learning group within the research department of Yandex, where he dealt with large-scale machine learning and data science problems on a daily basis. He also served as a software engineer at Yandex and the Russian Academy of Foreign Trade.

    Bauman received his PhD in Mathematics (Geometry and Topology) from Russia’s Moscow State University, where he also earned a Master of Science degree in Mathematics. He also obtained a Master of Science degree in Machine Learning from a joint program between the Moscow Institute of Physics and Technology and the Yandex School of Data Analysis in Russia.

    Research Talk Dominik Gutt: The Rise of Robo-Reviews – The Effects of Chatbot-Mediated Review Elicitation on Online Reviews

    16. September 2021

    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

    Research Talk Prof. Dr. Ali Sunyaev: Design Trade-Offs, Viability, and Management of Applications on Distributed Ledger Technology

    6. September 2021

    Standort: IWI-HSG, Müller-Friedbergstrasse 8, 9000 St.Gallen (Raum 52-5120) oder per Zoom

    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.

    Research Talk Dr. Monika Malinova Mandelburger: Cognitive diagram understanding and task performance in systems analysis and design

    26. April 2021

    Standort: Via Zoom, Müller-Friedberg-Strasse 8, St. Gallen

    Datum: 26.04.2021, 11:00

    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.
