- KonferenzbeitragAccessibility in Conceptual Modeling Research and Tools(Modellierung 2024, 2024) Sarioglu, Aylin; Metin, Haydar; Bork, DominikThe reports on Disability by the World Health Organization show that the number of people with disabilities is increasing. Consequently, accessibility should play an essential role in information systems engineering research. While software and web engineering research acknowledge this need by providing, e.g., web accessibility guidelines and testing frameworks, we show in this paper, based on a systematic review of the literature and current modeling tools, that accessibility is, so far, a blind spot in conceptual modeling research. With the paper at hand, we aim to identify current research gaps and delineate a vision toward more inclusive, i.e., disability-aware conceptual modeling. One key finding relates to a gap in research and tool support concerning physical disabilities. Based on these results, we further present the first modeling tool that can be used keyboard-only, thereby including users with physical disabilities to engage in conceptual modeling.
- ZeitschriftenartikelBausteinbasierte Modellierung von Prozesslandschaften mit der PICTURE-Methode am Beispiel der Universitätsverwaltung Münster(Wirtschaftsinformatik: Vol. 49, No. 4, 2007) Becker, Jörg; Algermissen, Lars; Pfeiffer, Daniel; Räckers, MichaelKernpunkteDie Prozesslandschaft als Menge aller in einer Organisation ausgeführten Geschäftsprozesse ist das neue Handlungsfeld der Prozessgestaltung in öffentlichen Verwaltungen. Zur Modellierung und Analyse einer Prozesslandschaft ist ein neuer methodischer Ansatz erforderlich:Die PICTURE-Methode dient zur modellierung der Prozesslandschaft. Sie besteht aus 24 domänenspezifischen Prozessbausteinen mit festem Abstraktionsniveau, die durch Attribute näher spezifiziert und zu einzelnen Prozessen zusammengesetzt werden können.Mit der PICTURE-Methode lässt sich die Prozesslandschaft deutlich effizienter modellieren, als dies klassische Modellierungsmethoden leisten können.Die PICTURE-Methode wurde im Praxiseinsatz in einem Modellierungsprojekt der Universität Münster evaluiert und hat die an sie gestellten Anforderungen erfüllt.AbstractPublic administrations face a strong pressure to reorganise caused by decreasing financial resources, a changing political environment, and increased customer demand.A process oriented visualisation, analysis and improvement of administrational processes is a key prerequisite for the successful organisational and technical change of public administrations within the current reorganisation activities.In order to successfully conduct reorganisation projects a coherent view on all administrational processes (the process landscape) and their interdependencies is of great value as a starting point.Common approaches to collect and visualise processes lead to such complex models that only a small percentage of the overall process landscape can be examined.The PICTURE-method as the core of this paper surpasses weaknesses of classical approaches and allows for a very efficient means of modelling the process landscape by using 24 domain specific reusable process building blocks. Hence by applying the PICTURE-method one can create a high degree of transparency as a base for reorganisation projects.In this paper we conceptually introduce the PICTURE-method and describe its practical application in a large modelling project within the administration of the University of Münster. We describe the experiences made by applying PICTURE and evaluate the method in terms of the requirements made by the project contractor.

- KonferenzbeitragDigital Transformation through Conceptual Modeling: The NEMO Summer School Use Case(Modellierung 2024, 2024) Völz, Alexander; Vaidian, IuliaIn the digital age, achieving a balance between human creative thinking and technology capabilities is crucial. Recognizing the potential of such collaborations, OMiLAB (Open Model Initiative Laboratory) developed a conceptual framework for establishing experimental innovation spaces in which skills to advance human-machine interaction can be taught and applied. The resulting Digital Innovation Environment incorporates both business and engineering perspectives, emphasizing the importance of interdisciplinary settings. Conceptual models and Digital Twins play a pivotal role within the environment, seamlessly bridging business strategies with cyber-physical systems. This paper offers a comprehensive understanding of the OMiLAB network, highlighting its alignment with the principles of a Community of Practice and emphasizing the knowledge exchange, exemplified by the NEMO Summer School Series. We present insights, best practices, and educational paradigms vital for navigating the digital transformation landscape.

- ZeitschriftenartikelFive questions to be clarified before starting to model conceptually(Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 15, Nr. 3, 2021) Elmar J. SinzConceptual modeling looks at the concept of a system. An important property of such a concept is that it can be viewed from at least two perspectives: The perspective of the users of the system and the perspective of the implementers. Based on these different perspectives, five sets of questions are identified that should be sufficiently answered before modeling is started. This is not a guarantee for the success of the modeling project, but it is necessary.

- WorkshopbeitragPreface for Workshop on Virtues and Values in Conceptual Modeling and Requirements Engineering(Modellierung 2024 Satellite Events, 2024) Rachmann, Alexander; Gulden, JensEthics and human values in developing software systems have long been a topic of discussion. A satisfactory solution like a collection of methods or model gallery for ethical argumentation has not yet been developed. The workshop provides a discussion forum in which various methods for incorporating human values into system development are discussed, as well as models, methods, and other specification techniques for incorporating values into conceptual modeling. Four submitted contributions are part the workshop. In a second practical part, the workshop gives a theoretical and practical introduction to the Square of Values (SoV) modeling approach.
- ZeitschriftenartikelReferenzmodellierungsforschung(Wirtschaftsinformatik: Vol. 46, No. 5, 2004) Fettke, Peter; Loos, PeterWithin the information systems discipline, reference modeling is a complex and heterogeneous research field. This paper reviews prior work based on a research framework. The framework comprises four elements: reference modeling languages, reference modeling methods, reference models and reference modeling context. Each element is discussed regarding its state of research and future research opportunities.
