    Vita

    Christoph Kotthaus studierte Wirtschaftsinformatik an der Universität Siegen. Sein Forschungsinteresse liegt im Bereich Mobile und Ubiquitous Computing. Bereits während seines Studiums konnte er sich als studentischer Mitarbeiter in das Forschungsprojekt INFOSTROM einbringen, wo er maßgeblich an der Entwicklung eines webbasierten Geoinformationssystems beteiligt war. Seine Diplomarbeit verfasste er zum Thema “Konzepte für Mobile Device Management“, wo er Anwendungsmöglichkeiten, die Einführung und die Einbindung von Mobile Devices (Smartphones, Tablets) in die IT-Infrastruktur von (Industrie-) Unternehmen bei einem Schienen- und Bahntechnikkonzern erarbeitet hat. Nach seiner Diplomarbeit arbeitete er dort als IT-Projektleiter, bis er als wissenschaftlicher Mitarbeiter an die Universität Siegen im Bereich Computergestützte Gruppenarbeit und Soziale Medien am Institut für Wirtschaftsinformatik zurückkehrte.

    • Fries, M., Nießner, J., Ludwig, T. & Kotthaus, C. (2025)Exploring AI Integration in SME Production Planning: Design Spaces and the Role of Workers

      IN Computer Supported Cooperative Work (CSCW) doi:10.1007/s10606-025-09512-6
      [BibTeX] [Abstract] [Download PDF]

      The pressure to improve products, services, and processes to remain competitive in the global market has fueled demand for affordable, high-quality, customized products with excellent availability and customer service. Production Planning and Scheduling (PPS) considers a wide range of internal and external factors in its attempts to align production with market demand. Advanced Planning and Scheduling (APS) systems have emerged to support PPS but suffer from issues such as deterministic views and practical uncertainties. Expectations are high that Artificial Intelligence (AI) and Machine Learning (ML) will support complex production planning tasks by analyzing operational data to generate optimal plans. However, there is currently little empirical research on production planning practices and what role AI might play. Our paper highlights current challenges in production planning practices and outlines design spaces for using AI and ML to support these practices. Based on an empirical study of three German small and medium-sized enterprises (SMEs) in the metal processing industry, we uncover how AI might estimate processing time and rework probability and thus we outline current design spaces for AI in production planning.

    • Rutz, P., Kotthaus, C., Pinatti de Carvalho, A. F., Randall, D. & Pipek, V. (2023)The Relevance of KES-Oriented Processes for the Implementation of ERP Systems: Findings From an Empirical Study in German SMEs

      IN Proceedings of the ACM on Human-Computer Interaction, Vol. 7, Pages: 313:1–313:34 doi:10.1145/3610104
      [BibTeX] [Abstract] [Download PDF]

      Past and current research has shown that Knowledge and Expertise Sharing (KES) is central to the appropriation of enterprise software such as Enterprise Resource Planning (ERP) systems. ERP implementation projects in Small and Medium-sized Enterprises (SMEs) are often driven by research and practice. However, they tend to focus on the ‚go live‘ moment rather than on the subsequent, much longer post-implementation phase. This, we argue, results in decreased utilisation over time and an increased need for workarounds. In this paper, we draw on an empirical study within four organisations which exposes the limitations of KES in ERP implementation projects in SMEs, especially in regard to the preparation of key users. Our findings suggest that, despite key users‘ essential role in these projects, they are often chosen haphazardly and are ill-prepared. As a result, they cannot fulfil their role of facilitating KES with end users, who end up appropriating ERP systems mostly through ‚learning by doing‘. This stems directly from complex and largely unrecognised processes involving consultants, hotlines, management, key users and end users. In this paper, we introduce and discuss specific socio-technical, KES-oriented measures which can potentially lead to sustainable KES throughout the ERP life-cycle for longer-term success.

    • Kotthaus, C., Vitt, N., Krüger, M., Pipek, V. & Wulf, V. (2022)Negotiating Priorities on the Shopfloor: A Design Case Study of Maintainers’ Practices

      IN Computer Supported Cooperative Work (CSCW) doi:10.1007/s10606-022-09444-5
      [BibTeX] [Abstract] [Download PDF]

      The coordination of maintenance work in manufacturing poses a crucial productivity factor in small and medium-sized companies (SMEs) but often seems to be rather neglected in practice as well as in much of the literature on maintenance. We shed light upon maintenance coordination work by presenting a design case study conducted in an SME over approximately two years. We took a participatory design-oriented approach, involving all roles on the shopfloor affected by maintenance work. In three major iterations during the pre-study, a release-ready prototype was developed and implemented by the users over the course of one year. The evaluation of the tool showed how a new and mostly unintended practice of information flow, error reporting, and prioritization emerged such that, for instance, foremen becoming a central node of communication, formal prioritization shifting away from higher management, and actual prioritization being done by maintainers. This paper contributes to the body of CSCW work on maintenance practice in SMEs by presenting detailed empirical findings on the coordination work of maintainers, as well as the evaluation of socio-technical interventions into maintenance practices.

      [BibTeX] [Abstract] [Download PDF]

      Regions and their innovation ecosystems have increasingly become of interest to CSCW research as the context in which work, research and design takes place. Our study adds to this growing discourse, by providing preliminary data and reflections from an ongoing attempt to intervene and support a regional innovation ecosystem. We report on the benefits and shortcomings of a practice-oriented approach in such regional projects and highlight the importance of relations and the notion of spillover. Lastly, we discuss methodological and pragmatic hurdles that CSCW research needs to overcome in order to support regional innovation ecosystems successfully.

      doi:10.18420/ecscw2020_ws02
      [BibTeX] [Abstract] [Download PDF]

      This ECSCW workshop draws attention to research and development projects (R&D) that deal with cooperative and collaborative practices in small and medium enterprises (SMEs). European companies are for the most part SMEs: nine out of every ten companies can be defined as an SME (Eurostat 2015). They cover a huge variety of branches and fields, including diverse examples such as manufacturing, construction or IT start-ups, and meanwhile, there is again a growing sphere of CSCW projects that recognize the importance of this field. The empirical methods applied in such SME centered projects include qualitative methods with participant observation, interviewing or conducting co-design workshops, but also quantitative methods like the use of questionnaires or eye-tracking systems. In the workshop, we open up for sharing and reflecting experiences of doing research in SMEs and for discussing the characteristics and challenges of this (old and new) field in CSCW.

      Abstract Although emergency services have already recognized the importance of citizen-initiated activities during disasters, still questions with regard to the coordination of spontaneous volunteers and their activities arise. Within our article, we will present a technological approach based on public displays which aims to foster situated crowdsourcing between affected citizens, spontaneous volunteers as well as official emergency services. We will address the research question: How can the situated tasks performed by spontaneous volunteers be supported by the use of public displays during disasters? First we will present the current state of the art with regard to the coordination practices of spontaneous volunteers and emergency services within disaster situations as well as related problems, potentials and specifics of situated crowdsourcing and public displays. To gain insight into actual coordination practices, we conducted an empirical study with 18 different stakeholders involved in disaster management. Based on the literature review and our empirical study, we have derived a technical concept that supports the task and activity management of spontaneous volunteers as well as the coordination both of the demands of affected people and the offers from spontaneous volunteers. We have implemented our concept as the public display application ‘City-Share‘, which provides a robust communication infrastructure and encompasses situated crowdsourcing mechanisms for managing offers and demands of activities on-the-ground. Based on its evaluation with several users, we will discuss our findings with regard to the assignment of tasks on-the-ground and situated crowdsourcing during emergencies. We outline that City-Share can improve a community’s disaster resilience, especially when focusing on the kind of collaborative resilience emerging between official stakeholders and spontaneous volunteers or affected citizens at a local level.

      [BibTeX] [Abstract] [Download PDF]

      Enterprises are increasingly starting to apply a user-centric perspective in their product and service development processes. This paper uses the concept of customer journey mapping (CJM) to visualize customers’ needs and perceptions throughout all of their relationships with an enterprise to improve development processes. Currently, CJM focuses more on business-to-consumer (B2C) relationships than on business-to-business (B2B) settings. In contrast, we here examine how to conceptualize a CJM template for B2B relationships by researching Bosch Packaging Technology – Business Unit Pharma, a large pharmaceutical packaging company. We employ user narratives from expert interviews, design workshops, and customer interviews/observations to visualize knowledge about customers in a CJM.

      Zusammenfassung Das aktuelle Verständnis von Industrie 4.0 umfasst oftmals die Vision einer vollautomatisierten und Technologie-determinierten Entwicklung der deutschen Industrie. Eine praktische Ausgestaltung einer solchen Vision bietet dabei keine hinreichende Option für den Mittelstand – den eigentlichen Treiber der deutschen Wirtschaft. Speziell bei kleineren und mittelständischen Unternehmen sichern die eigenen Mitarbeiter/innen sowie deren Erfahrungen und Arbeitsver-mögen maßgeblich den wirtschaftlichen Erfolg und müssen bei der Ausgestaltung von Industrie 4.0-Konzepten und -Technologien in den Fokus gerückt werden. Bei 72 T. Ludwig et al. 1 3 der Betrachtung der Mitarbeiter bzw. der Mitarbeiterinnen im Zentrum des Mittel-standes, fallen bei der praktischen Ausgestaltung von Industrie 4.0 eine Vielzahl sozialer Fragestellungen an, welche vor allem aber im Betrieb von Unternehmen und Betriebsrat bearbeitet und sozialpartnerschaftlich ausgestaltet werden müssen. In diesem Artikel werden die aktuellen Spannungsfelder präsentiert, in welchen die sozialen Fragestellungen angesiedelt sind. Diese wurden auf Basis eines Experten-workshops mit Geschäftsführern und Unternehmensberatern kleiner und mittelstän-discher Unternehmen sowie durch verschiedene Interviews mit Vertretern der IG Metall im Hinblick auf die Veränderung von Arbeit im Kontext von Industrie 4.0 erhoben.

      A growing body of research in the area of information systems for crisis management is based on data from social media. After almost every larger disaster studies emerge with the focus on the specific use of social media. Much of this research is based on Twitter data, due to the ease of access of this (mainly public) data, compared to (more closed) data, such as Facebook or Google+. Based on the experience gained from a research project on social media in emergencies and our task to collect social media data sets for other partners, we present the design and evaluation of a graphical user interface that supports those stakeholders (such as emergency services or researchers) that are interested in creating social media datasets for further crisis management research. We do not specifically focus on the analysis of social media data. Rather we aim to support the gathering process and how actors without sophisticated technical skills can be supported to get what they want and especially need: relevant social media data. Within this article, we present a practice-oriented approach and implications for designing tools that support the collection of social media data as well as future work.

      The current understanding of `Industry 4.0′ often includes the vision of a fully-automated and technology-driven development of the German industry. But the practical configuration of such a vision is not an appropriate option for small and medium companies, which are the actual driver of the German economy. Especially for smaller and medium sized companies, the own staff, as well as their experiences and work capacity decisively secure the economic success and need to be put in the spotlight of industrial 4.0 concepts and technologies. When considering the employee as one of the central factors of success within small and medium companies, the practical adaption of fully-automated and technology-driven concepts raise a variety of social issues, which need to be addressed by the social partnership, such as employer organizations, employee organizations as well as scientific partners. This article presents the current social issues as well as areas of conflict in which these social issues are settled. Such issues were collected on the basis of an expert workshop with managers and business consultants of small and medium companies and various interviews with representatives from the labor union IG Metall and the employers‘ associations in regard to the change of work in the context of `Industry 4.0′.
