    3D representation of business process models
    (Modellierung betrieblicher Informationssysteme (MobIS 2008), 2008) Betz, Stefanie; Eichhorn, Daniel; Hickl, Susan; Klink, Stefan; Koschmider, Agnes; Li, Yu; Oberweis, Andreas; Trunko, Ralf
    3D technologies open up new possibilities for modeling business processes. They provide higher plasticity and eliminate some deficits of conventional 2D process modeling such as the limitation of the amount of information to be integrated into a process model in an understandable way. The aim of this paper is to show how the usage of an additional visual modeling dimension may support users in compactly representing and animating business process models. For this purpose, we propose an approach for 3D representation of business process models based on Petri nets. The need for the third modeling dimension is pointed out with three modeling scenarios for which we propose modeling improvements in 3D space. Early evaluations indicate the effectiveness of our approach, which goes beyond conventional modeling tools for business processes.

    Automated assessment of process modeling exams: basic ideas and prototypical implementation
    (Modellierung 2016 - Workshopband, 2016) Thaler, Tom; Houy, Constantin; Fettke, Peter; Loos, Peter
    The assessment of process modeling exams is a time consuming and complex task. It is desirable to give each student a detailed feedback on their solution in terms of syntactic, semantic, and pragmatic quality. It is obvious that especially in the case of mass courses with hundreds of participants, individual grading of modeling exams by humans is challenging: Besides reliability, consistency, and validity, the efficiency of the grading process must be guaranteed. Against that background, this paper aims at developing first ideas for an automated assessment of process modeling exams. The goal is to improve modeling education while teaching students not only to model correctly but to develop good models. Our ideas were prototypically implemented and applied in an exemplary scenario with promising results. It was possible to identify limitations but also to derive reliable semi-automated approaches for the assessment of process modeling exams.

    Bpaas modelling: business and IT-cloud alignment based on adoxx
    (Modellierung 2016 - Workshopband, 2016) Woitsch, Robert
    Business Process as a Service (BPaaS) is a new paradigm in Cloud Computing using domain-specific business processes as a mediator for business and IT-Cloud alignment. Therefore, business process models are extended with cloud-specific concepts. This paper introduces the modelling concepts and mechanisms to bridge the semantic distance between domain-specific business processes and IT-Cloud deployable workflows. A prototype has been developed in the H2020 project CloudSocket, where the current status of the modelling tool is available for the research community on ADOxx.org.

    Community application editor: collaborative near real-time modeling and composition of microservice-based web applications
    (Modellierung 2016 - Workshopband, 2016) Lange, Peter De; Nicolaescu, Petru; Derntl, Michael; Jarke, Matthias; Klamma, Ralf
    Research shows a gap in terms of requirements elicitation between developers and endusers. Due to the low technical expertise of some members of online communities, they often cannot collaborate efficiently with developers and cannot provide continuous feedback during application development processes. However, collaborative modeling processes can play an important role in education, enforcing best-practices, support rapid prototyping and lower the communication and collaboration barriers between developers and end-users. This paper presents a tool for collaborative modeling of Web applications in near real-time and their automatic generation. Early evaluation with end-users in simulated community settings show promising results for the interplay of modeling and collaboration in requirements gathering and Web application design and development. We claim that near real-time modeling on the Web has the potential to bring together stakeholders during design and development and offers a new perspective on model-based Web Engineering.

    Daten-Ökosysteme wider Willen: Herausforderungen des Pay-as-you-live-Geschäftsmodells im Kontext deutscher Krankenversicherungen
    (HMD Praxis der Wirtschaftsinformatik: Vol. 58, No. 3, 2021) Wulf, Nele; Betz, Stefanie
    In dem vorliegenden Beitrag wird der aktuelle Trend, Pay-as-you-live-Systeme (PAYL) in Verbindung mit Krankenversicherungen anzubieten, analysiert. PAYL-Systeme bedeutet konkret die kontinuierliche Erfassung von Gesundheitsdaten mithilfe technischer Geräte und Übermittlung dieser Daten an Versicherungen sowie die Auszahlung von Boni für erreichte Fitnessziele. Zunächst wird eine Definition von PAYL-Systemen dargelegt, dann werden die technischen Rahmenbedingungen erläutert, schließlich werden die Auswirkungen dieser sozio-technischen Systeme näher beleuchtet. Dies geschieht auf Grundlage unserer empirischen Untersuchung. Die drei identifizierten Hauptkonflikte betreffen die Genese von PAYL, seine Auswirkungen auf den Wert der Datensouveränität besonders für Versicherte und die Schwierigkeit, für den Anspruch auf Prävention und Kostenersparnis durch PAYL Evidenz zu erzeugen. Diese Konflikte werden diskutiert, um sowohl die direkten wie auch indirekten Auswirkungen der Digitalisierung und der Ökonomisierung des Sozialen durch PAYL zu beleuchten. This paper analyzes the current trend of offering pay as you live systems in conjunction with health insurance. In concrete terms, PAYL-systems mean the continuous recording of health data with the aid of technical devices and transmission of this data to insurance companies, as well as the payment of bonuses for fitness goals achieved. First, a definition of PAYL-systems is presented, then the technical framework is explained, and finally the effects of these socio-technical systems are examined in more detail. This is done on the basis of our empirical investigation. The three main conflicts identified relate to the genesis of PAYL, its impact on the value of data sovereignty especially for insured individuals, and the difficulty of generating evidence for the PAYL prevention and cost savings claim. These conflicts are discussed in order to shed light on both the direct and indirect effects of digitization and the economization of the social through PAYL.

    Development and evaluation of a component-based context modelling method
    (Modellierung 2016 - Workshopband, 2016) Koç, Hasan; Sandkuhl, Kurt
    In very general terms, a method describes a systematic procedure for problem solving including the required aids and resources. This paper is a continuation of our earlier work that reported on the practices and experiences in the development of a component-based context modelling method in the area of information systems development. The contributions of the paper are (1) the detailed development process of the context modelling method, with a particular focus on artefact evaluation by means of the Framework for Evaluation in Design Science Research (FEDS) (2) additional experiences and lessons learned from the method engineering and application process.

    Evaluation of Social Value Icons for a Domain-Specific Modeling Language
    (INFORMATIK 2017, 2017) Fritsch, Andreas; Betz, Stefanie
    Sustainability is one of the major challenges in modern society. Life Cycle Assessment with regard to sustainability is one of the current tools to asses and communicate a product’s impact on sustainability. But currently, life cycle assessments are difficult to communicate to the end-user due to their inherent complexity. Domain-specific modeling languages (DSML) can help to communicatecomplex information. Therefore, we have developed a DSML – TracyML – as a visual language to effectively communicate social sustainability of a product life cycle. Additionally, to help with effectively communicating the different aspects of social sustainability such as child labor and excessive working hours (among others), we have enriched the DSML with social value icons, representing these different aspects. In order to evaluate whether the icons are understood as we intended them to be, we conducted a survey. Thus, in this paper, we present an evaluation of the associativeness of TracyML’s social value icons based on the Multiple Index Approach using an online survey. The main outcome of the evaluation is that the icons (except for one) are all comprehensible and associated with the correct social values.
