- 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.
- ZeitschriftenartikelEliciting and Modeling Business Process Stories(Business & Information Systems Engineering: Vol. 60, No. 2, 2018) Simões, David; Antunes, Pedro; Carriço, LuisMost business process modeling tools used today encourage the rendition of lean, prescribed and clearly coordinated activities, which often clash with far more intricate business realities. This paper evaluates an alternative approach that adopts concepts from storytelling and sense-making theories to elicit process stories. The viability of this approach is tested in a case study involving sixteen individuals from the same organization who tell their personal views about a business process, thus gathering a total of twenty process stories. The obtained results suggest that process stories may increase the meaningfulness, contextualization and overall richness of process models.
- ZeitschriftenartikelMehrebenen-Modellierung(Wirtschaftsinformatik: Vol. 56, No. 6, 2014) Frank, UlrichDomänenspezifische Modellierungssprachen (engl.: “domain-specific modeling languages”, DSMLs) versprechen deutliche Vorteile gegenüber universellen Modellierungssprachen. Ihr Entwurf ist allerdings mit einer essentiellen Herausforderung verbunden. Um ansehnliche Skaleneffekte zu erreichen, empfiehlt sich die Entwicklung von DSMLs, die in einer größeren Nutzungsbandbreite einsetzbar sind. Gleichzeitig spricht der Gewinn an Modellierungsproduktivität im Einzelfall für Sprachkonzepte, die an individuelle Anforderungen angepasst sind. In dem vorliegenden Beitrag wird ein neuartiger Ansatz zur konzeptuellen Modellierung wie auch zur Konstruktion von Informationssystemen präsentiert, der durch die faktische Nutzung von Fachsprachen inspiriert ist – die Mehrebenen-Modellierung. Im Unterschied zu traditionellen Spracharchitekturen wie der „Meta Object Facility“ (MOF) basiert er auf einer rekursiven Architektur, die eine beliebige Zahl von Klassifikationsebenen ermöglicht und dadurch den Entwurf von Sprachhierarchien – von einer Referenz-DSML bis hin zu „lokalen“ DSMLs – erlaubt. Auf diese Weise wird nicht nur der essentielle Konflikt des Entwurfs von DSMLs deutlich entschärft, sondern auch die Wiederverwendung und Integration von Software-Komponenten im Allgemeinen gefördert. Zudem ermöglicht der Ansatz die Reduktion von Modellkomplexität, indem er die Dichotomie von Spezialisierung und Instanzierung teilweise aufhebt. Darüber hinaus integriert er eine Metamodellierungssprache mit dem Metamodell einer Metaprogrammiersprache, wodurch ausführbare Modelle ermöglicht werden. Die Spezifikation der Spracharchitektur wird ergänzt durch die Darstellung von Anwendungsszenarien, die die Potentiale der Mehrebenen-Modellierung verdeutlichen, sowie eine kritische Betrachtung ihrer Besonderheiten.AbstractDomain-specific modeling languages (DSMLs) promise clear advantages over general-purpose modeling languages. However, their design poses a fundamental challenge. While economies of scale advocate the development of DSMLs that can be used in a wide range of cases, modeling productivity demands more specific language concepts tuned to individual requirements. Inspired by the actual use of technical languages, deutsch: “Fachsprachen” this paper presents a novel multilevel modeling approach to conceptual modeling and to the design of information systems. Unlike traditional language architectures such as Meta Object Facility (MOF), it features a recursive architecture that allows for an arbitrary number of classification levels and, hence, for the design of hierarchies of DSMLs ranging from reference DSMLs to “local” DSMLs. It can not only diminish the conflict inherent in designing DSMLs, but enables the reuse and integration of software artifacts in general. It also helps reduce modeling complexity by relaxing the rigid dichotomy between specialization and instantiation. Furthermore, it integrates a meta-modeling language with a metamodel of a reflective meta-programming language, thereby allowing for executable models. The specification of the language architecture is supplemented by the description of use scenarios that illustrate the potential of multilevel modeling and a critical discussion of its peculiarities.
