Making Data Valuable for Smart City Service Systems - A Citizen Journey Map for Data-driven Service Design

Due to the digital transformation of smart cities (SCs), improved access to digital technologies can enable gathering and utilization of data which can serve as key resources for services to improve citizens’ quality of life. SCs face challenges making data valuable for the design of such data-driven services. Service literature lacks in providing methods to facilitate the design of these services while addressing the requirements of SCs as smart service systems. This paper presents the Data-driven Citizen Journey Map (DCJM), a method which supports designing data-driven services in collaborative Design Thinking (DT) workshops. Following design science research (DSR), we developed and evaluated our method through five iterations of workshops, interviews, and questionnaires with SC experts and students. Our evaluations indicate that the DCJM, including all promoted constructs, is useful to support data-driven service design in SCs and that it can be combined with existing methods in comprehensive service development processes

INTER-ORGANIZATIONAL DATA GOVERNANCE: A LITERATURE REVIEW

Digitization and the associated quantitative increase of data continue to advance. Simultaneously, companies share their data in inter-organizational networks, and this new form of interaction also requires a new form of governance. Existing governance approaches that only operate within company boundaries cannot achieve the new form of interaction. To overcome this inadequacy, we conducted a systematic literature review. We identified four constructs of inter-organizational governance. We used these constructs to develop our research framework and they serve as a basis for our results. The constructs are structure, processes, participants, and success. Moreover, we identified various findings within the constructs\u27 domains. This contribution mirrors the current state of research and lays a foundation for future efforts. Based on the results, we propose several research streams for an in-depth examination of the individual constructs. Limitations include possible undiscovered contributions within the literature analysis

Blockchain for Smart Mobility—Literature Review and Future Research Agenda

Today’s cities face numerous challenges due to climate change and urbanization. The concept of a smart city aims to help cities to address these challenges by adapting modern information and communication technology. Smart mobility and transportation form one important aspect of smart cities. Inefficient mobility in cities can lead to problems such as traffic congestion, which results in frustration for residents and a decrease in the quality of life. Against the backdrop of global warming, cities also strive to reduce CO2 emissions, an attempt which requires sustainable and novel mobility concepts. Blockchain is a current technology, said to have huge potential, that is being investigated for application in many facets of smart cities. In the context of smart mobility, blockchain can be used for transactions relating to ridesharing and electric charging, handling of interactions of platoon members, or serving as a foundation for communication between vehicles. Although initial research about this topic exists, it is distributed among different use-cases and applications. This article conducts a systematic literature review to analyze blockchain’s role in mobility and transportation in smart cities, and its potential to increase efficiency in these areas. With this review, we aim to consolidate and summarize the current knowledge about this topic. As a first result, we present the findings from our literature review, which can be divided into five categories of use-cases. We also present a platform for further research about this emerging topic by identifying promising future research avenues. For this purpose, we derive a future research agenda based on our findings

Blockchain for AI Data – State of the Art and Open Research

Artificial intelligence (AI) and blockchain are two current trend terms. Although they are mostly investigated separately, blockchain and AI benefit from each other. A blockchain, for example, supports AI through the management and sharing of data. Since AI systems are highly dependent on a large amount of high-quality training data, a blockchain can serve as a new platform to store and exchange data. Notwithstanding the blockchain’s multifaceted potential for data sharing, there is currently no comprehensive overview of this promising application. By conducting a systematic literature review, this article aims to close this research gap. This article provides an overview of the existing approaches, their functionality, as well as their intended benefits. Furthermore, risks and open research challenges are investigated

Enhancing Inter-Organizational Data Governance via Blockchain – Shaping Scopes and Research Avenues

With increasing technological and competitive challenges, the number of inter-organizational networks that share data to improve performance constantly grows. Governing these inter-organizational environments is challenging. Nevertheless, inter-organizational data governance (IODG) is the linchpin of successful data sharing in collaborations. Simultaneously, the attention on blockchain technology steadily increases. Its decentralized nature and focus on transparency and trust make blockchain fascinating for practitioners and researchers in the context of data sharing. A symbiosis of IODG and blockchain is still lacking, although both concepts will become more critical in future. This paper aims to fill this gap and lay the foundation for future research in the context of blockchain and IODG. Four IODG modes are used as a research framework and are directly addressed via blockchain-based concepts within a grounded theory-based literature review to utilize the information systems (IS) body of knowledge. This paper also uncovers many research gaps for future IS research
