    Evolutionary Method Engineering – A Case Study in Meta Modeling
    (Meta-modelling and ontologies – Proceedings of the 2nd Workshop on Meta-Modelling – WoMM 2006, 2006) Becker, Jörg; Seidel, Stefan; Pfeiffer, Daniel; Janiesch, Christian
    Meta modeling is a widely established means for developing conceptual modeling methods (CMM). Here, we show how a CMM for the structured conceptual design of management information systems has been developed in an evolutionary process based on meta modeling. The aim of management information systems is to satisfy the information need managers have to successfully accomplish their tasks. The quality of management decisions is highly dependent on the information they are based on. A structured conceptual design of management information systems is a crucial task that has to precede their implementation and monitoring. Several conceptual modeling methods have been developed in order to support the specification of data warehouse structures and management information systems. However, none of them was found to be appropriate to bridge the communication gap in the process of requirements analysis. Thus, in an ongoing research effort, a CMM has been designed to adequately support the conceptual design of management information systems. Several case studies were conducted and in an iterative process the findings were incorporated to improve the initial CMM. The result of this process is a CMM quite different to the original one. The aim of this paper is to elaborate on the evolutionary development of a CMM using meta modeling and to show how it has successfully been applied in multiple case studies.

    In Search of Information Systems (Grand) Challenges
    (Business & Information Systems Engineering: Vol. 57, No. 6, 2015) Becker, Jörg; Brocke, Jan; Heddier, Marcel; Seidel, Stefan
    The paper reports on the results of a Delphi study with 143 information systems (IS) academics that was designed to explore what IS academics perceive to be the grand challenges of the IS discipline. The results provide evidence that the scholarly IS discipline is still much concerned with itself, for instance, in terms of its identity, relevance, foundational theory, or methodological pluralism – suggesting that the old debate on IS identity is not yet overcome. It thus cannot be claimed that the study identifies the grand challenges of the discipline – still it becomes noticeable that the academic community sees potentials for the IS discipline to have societal impact. A total of 21 challenges are identified, of which six challenges are categorized as “meta challenges for further developing the IS discipline” and the remaining 15 challenges are categorized as “IS research challenges” pertaining to socio-technical systems, IS infrastructures, society and ecology, as well as social well-being and affectivity. We provide a ranking of all challenges according to their relevance, potential impact, and possible time frame of realization. The results have some important implications for IS as a discipline as well as its prospective future societal role. It is hoped that through our study we can contribute to the important debate on the challenges of the academic IS discipline.

    Konfigurative Referenzmodellierung zur Fachkonzeption von Data Warehouse-Systemen mit dem H2-Toolset
    (Integration, Informationslogistik und Architektur, 2006) Knackstedt, Ralf; Seidel, Stefan; Janiesch, Christian
    Im Rahmen einer auf einer konsensorientierten Wahrheitskonzeption basierenden Informationsbedarfsermittlung ist es von Bedeutung, die Auffassungen mehrerer Sachverständiger zusammenzuführen. Dieser Beitrag identifiziert den Einsatz konfigurierbarer Referenzmodelle als wichtiges Instrument zur Ausweitung der Expertisenbasis von Informationsbedarfsermittlungen. Konfigurative Referenzmodelle ermöglichen durch die für sie konstituierenden Wenn-Dann-Aussagen die Formulierung von Theorien sowohl zur angemessenen inhaltlichen Gestaltung von Data Warehouse-Systemen in verschiedenen Kontexten als auch die Explikation modellierungstheoretischer Aussagen zur geeigneten Gestaltung der konzeptionellen und repräsentationellen Aspekte von Modellierungsmethoden für Data Warehouse-Fachkonzepte. Für die Erstellung und Nutzung entsprechender referenzmodellbasierter Aussagesysteme stellt der Beitrag eine umfassende Werkzeugunterstützung in Form des erweiterten H2-Toolsets vor.

    Reuse, Reduce, Support: Design Principles for Green Data Mining
    (Business & Information Systems Engineering: Vol. 65, No. 1, 2023) Schneider, Johannes; Seidel, Stefan; Basalla, Marcus; Brocke, Jan
    This paper reports on a design science research (DSR) study that develops design principles for “green” – more environmentally sustainable – data mining processes. Grounded in the Cross Industry Standard Process for Data Mining (CRISP-DM) and on a review of relevant literature on data mining methods, Green IT, and Green IS, the study identifies eight design principles that fall into the three categories of reuse, reduce, and support. The paper develops an evaluation strategy and provides empirical evidence for the principles’ utility. It suggests that the results can inform the development of a more general approach towards Green Data Science and provide a suitable lens to study sustainable computing.

    Towards Tool Support for Configurative Reference Modeling - Experiences from a Meta Modeling Teaching Case
    (Meta-modelling and ontologies – Proceedings of the 2nd Workshop on Meta-Modelling – WoMM 2006, 2006) Delfmann, Patrick; Janiesch, Christian; Knackstedt, Ralf; Rieke, Tobias; Seidel, Stefan
    The adaptation of conceptual information models to specific requirements has been discussed for several years. Especially, different approaches to information model configuration have reached certain popularity. Nevertheless, up to now, model configuration is not supported sufficiently by recent modeling tools. In this paper, we present the implementation of a meta model based model configuration approach in order to close this gap. The results of the implementation are two modeling tool add-ons that enable model configuration based on the modeling tools ARIS and H2. The implementation was conducted in the course of a teaching seminar at the University of Münster. Besides the configuration approach as well as architectures and functionalities of the developed tools, we discuss teaching experiences.
