PublicationUnlocking digital value at the intersection of organizational digital transformation and digital business ecosystems( 2023-07-15)Digital technologies promise to unlock new types of value for organizations and fundamentally change existing business practices. The challenge for today’s organizations is not buying into the new mantra related to digital transformation but understanding what they need to do to adapt - individually and in relationship with other organisations. This chapter leverages decades of academic thought leadership as a way to establish a set of managerial implications to guide organizations through their digital evolution. The challenge from an academic perspective is that these implications sit at the intersection between two mostly isolated research streams: Organizational digital transformation (ODT) focuses on the digital improvement process of individual incumbents, and digital business ecosystems (DBEs) focuses on digitally-enabled value co-creation across organizations. Joining the forces of both research streams, our work aims to assess what empirical evidence and theoretical explanation exist at their intersection. After conducting a comprehensive two-phased literature review, we derive four convergent assumptions and draw implications for managers. We also share a framework that illustrates ODT and DBE as a ‘means to an end of the other’ connected in a cyclical relationship to meet digitally induced challenges. Building on real-world examples, this framework offers a guide to support organizations in their digital journey individually and in the context of digital ecosystems.

PublicationThe enforcement and bankruptcy of blockchain-based assets (Crypto-Assets)( 2023)Blockchain technology is on the rise. As the total market capitalization of blockchain- based crypto-assets continues to rise, more and more companies are turning to blockchain-based applications, such as smart pay-per-use systems. For example, micropayments can be efficiently carried out using tokens specifically implemented for this purpose on the respective blockchain application, which can in turn be exchanged for fiat currency if needed. As more and more wealth is accumulated in blockchain-based crypto-assets, the question of how these new assets behave in individual and general enforcement becomes increasingly relevant. This article dissects these questions and demonstrates where German Code of Civil Procedure (Zivilprozessordnung- ZPO) and the German Insolvency Code (Insolvenzordnung- InsO) de lege lata are not able to ensure effective and comprehensive l enforcement of blockchain-based crypto-assets. These results should encourage the legal debate and call on the legislature to remove the legal obstacles de lege ferenda.

PublicationEngineering Digital Twins and Digital Shadows as Key Enablers for Industry 4.0( 2023)Industry 4.0 opens up new potentials for the automation and improvement of production processes, but the associated digitization also increases the complexity of this development. Monitoring and maintenance activities in production processes still require high manual effort and are only partially automated due to immature data aggregation and analysis, resulting in expensive downtimes, inefficient use of machines, and too much production of waste. To maintain control over the growing complexity and to provide insight into the production, concepts such as Digital Twins, Digital Shadows, and model-based systems engineering for Industry 4.0 emerge. Digital Shadows consist of data traces of an observed Cyber-Physical Production System. Digital Twins operate on Digital Shadows to enable novel analysis, monitoring, and optimization. We present a general overview of the concepts of Digital Twins, Digital Shadows, their usage and realization in Data Lakes, their development based on engineering models, and corresponding engineering challenges. This provides a foundation for implementing Digital Twins, which constitute a main driver for future innovations in Industry 4.0 digitization.

PublicationDigital shadows: Infrastructuring the Internet of Production( 2023)Digitization in the field of production is fragmented in very different domains, ranging from materials to production technology to process and business models. Each domain comes with specialized knowledge, often incorporated into mathematical models. This heterogeneity makes it hard to naively exploit advances in data-driven machine learning that could facilitate situation adaptation and experience transfer. Innovative combinations of model-driven and data-driven solutions must be invented but also made comparable and interoperable to avoid ending up in information silos. In future World Wide Labs (WWLs), experiences can be shared, aggregated, and used for innovation. WWLs will be complex, evolving socio-technical networks of interconnected devices, software, data stores, and humans as users and contributors of expert knowledge and feedback. Integrating a large number of research labs, engineering, and production sites requires a capable cross-domain Internet of Production (IoP) infrastructure. The IoP project claims Digital Shadows (DSs) to offer a shared conceptual foundation for infrastructuring the IoP. In engineering, DSs were introduced as the data provision link to Digital Twins, whereas in computer science, DSs generalize the well-established concept of database views. In this chapter, we elaborate on the roles of DSs in infrastructuring the IoP from three perspectives: analytic functionality, conceptual organization, and technical networking. As an example where an integrative DS-like approach is already highly successful, we showcase the approach and infrastructure of the process mining field.

PublicationSmart grids and energy markets: Towards a real-time energy system( 2023)This chapter provides an overview on how IS and digital technologies can support the integration of increasing shares of renewable energy sources into electricity grids and energy markets by describing: current challenges and opportunities to bridge the existing "digital gap" (Section2); by highlighting relevant technologies (Section 3); by giving examples of what a real-time energy system may look like (Section 4); and by outlining key challenges on the way towards a real-time energy system (Section 5). In this context, the chapter underlines the particular importance of establishing and implementing standards and using latest methods for the analysis of data to actively integrate millions of (heterogeneous) devices and assets into the system. Digital technologies can help in this process both to capture each of these devices in the system and to automate their actions via data exchange in real-time, as well as to preserve necessary privacy of market participants.

PublicationPigConomy: Evidence-based Analysis of Empirical Data from Livestock Farming and its Utilisation( 2023)PigConomy aims to optimize processes in meat production. Data collected during animal husbandry and slaughter are used as raw material for this improvement. These process data are not only presented in tabular form and charts but also form the basis for extracting causal relationships between husbandry decisions and animal health diagnosed at the slaughterhouse. These causal reltionships are represented by a statistical model. This knowledge thus represents a tangible and monetary asset for optimizing production processes in the manufacture of meat, the use of which must be monitored and incentivized. PigConomy illustrates with a proof of concept the monetization of data from the process chain for the production of pork. However, not only the economic optimization of husbandry processes is in the foreground, but also the improvement of animal welfare, as it is quantitatively determined at the slaughterhouse. Animal welfare can be improved by using the knowledge of the causal relationships between husbandry decisions and animal health, analogous to husbandry efficiency. This contribution describes PigConomy as the core of a data management ecosystem. In addition, functional additions are discussed to make PigConomy sustainable.

PublicationElektromobilität im Tourismus - Herausforderungen und potenzielle Lösungsansätze( 2023)Durch die direkte Verbindung von Mobilität und Tourismus beeinflusst die fortschreitende Elektrifizierung des Verkehrs auch unmittelbar die Tourismusbranche. Öffentlich zugängliche Ladeinfrastruktur gewinnt immer mehr an Bedeutung und so werden auch an touristischen Zielorten Lademöglichkeiten nachgefragt. Doch gerade dort stellt der wirtschaftliche Betrieb eine große Herausforderung dar. Grund hierfür sind vor allem volatile Ladebedarfe, die hohe Lastspitzen und aufgrund der Bepreisung im deutschen Stromsystem hohe Kosten nach sich ziehen können. Nach einer kurzen Darstellung der aktuellen Kostenstruktur von Ladeinfrastruktur werden daher touristische Zielorte anhand verschiedener Ausprägungen, die das Lastprofil und damit die Kosten beeinflussen können, charakterisiert. Anschließend werden vielfältige, insbesondere durch die Digitalisierung realisierbare, Lösungsansätze aufgezeigt und mögliche zukünftige Entwicklungen diskutiert.
