    Flexible deep modeling with melanee
    (Modellierung 2016 - Workshopband, 2016) Atkinson, Colin; Gerbig, Ralph
    Multi-level modeling has gained increasing attention in recent years as the maturity of the supporting tools has grown. One of the most advanced tools for deep modeling is Melanee [Me16] which supports modeling through deep, multi-format, multi-notation user-defined languages. “Multiformat” refers to seamlessly editing a language in several formats in parallel (e.g. diagrammatic, textual and tabular) while “multi-notation” denotes the ability to mix notations arbitrarily (i.e. to show one part of a model in a general-purpose, UML-like, notation and one part in a domain-specific notation such as BPMN). The deep modeling component of the tool, underpinned by the orthogonal classification architecture and deep instantiation, allows models to contain as many classification levels as needed to concisely represent the domain in hand. This demonstration shows the capabilities of the Melanee tool in the context of defining a language to model the structure of an enterprise.

    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.

    The potentials of a code generator which faces the stress ratio of requirements engineering processes in agile development projects
    (Modellierung 2016 - Workshopband, 2016) Kuhlen, David; Speck, Andreas
    The agile software development method is common in many software development companies worldwide. The following paper approaches an universal problem of agile development projects in the whole software development branch of industry. Unfortunately, in many cases, the requirements are incomplete and the projects are under-specified. Imprecise requirements and specifications cause not only problems in the development, but they also result in inaccurate cost estimations. This leads to problems even in the development and in the requirements engineering. Moreover, the lack of clear specifications may lead to further customer requests at the development time. They might be realized at very high costs. This increases the time pressure for the developers. In order to realize the software in time, the developers lower the quality level of the code. A lack of quality causes technical debts which reduces the economic efficiency of the system considerably. A potential solution, proposed in the paper, is the use of code-generation systems. The use of a code generator could offer potentials to improve the processes of requirements engineering. The support of these generators enables the software developers to focus on the requirements engineering. As the generated code contributes directly to the sprint goal, this approach could be well accepted by the developers. The potentials of such a concept are investigated.

    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.

    Invigorating event-driven process chains - towards an integrated meta model for EPC standardization
    (Modellierung 2016 - Workshopband, 2016) Jannaber, Sven; Karhof, Arne; Riehle, Dennis M.; Thomas, Oliver; Delfmann, Patrick; Becker, Jörg
    When deciding about appropriate modelling languages, the degree of standardization often represents an important decision criterion. Although the EPC is commonly used for process modelling in the last decades, the absence of an official standard leads more and more to its nonconsideration. A coherent meta model is a pillar for the specification of process modelling languages. Accordingly, this work builds the basis for further standardization by providing an integrated meta model for the EPC. The resulting meta model therefore supports the invigoration of the EPC by impelling the future standardization effort.

    Towards a multi-faceted framework for semantics in enterprise modeling languages
    (Modellierung 2016 - Workshopband, 2016) Braun, Richard
    The semantic specification of Enterprise Modeling Languages (EMLs) is a challenging task that is primarily caused by the immanent subjectivity in the context of enterprise modeling. This covers the interpretation of respective meta model constructs due to their references to the reality. In contrast, EMLs may also contain formal semantics in regard of automating specific parts. Despite the generally accepted relevance of semantics for the application of EMLs, current research lacks in the provision of appropriate description means and largely omits semantic investigations. This paper therefore proposes a multi-faceted framework for the analysis and description of EML semantics in order to increase the awareness of relevant influences. The framework consists of an ontic and epistemological dimension in its core, as material semantics finally address such fundamental aspects. On this basis, several wrapping dimensions are outlined: Conceptualization dimension, pragmatic dimension, representation dimension and the final consensus dimension.

    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.

    Qualität von Geschäftsprozessmodellen aus dem Blickwinkel der Anforderungsanalyse
    (Modellierung 2016 - Workshopband, 2016) Laue, Ralf
    Kommunikation von Anforderungen ist nur einer von zahlreichen Einsatzzwecken von Geschäftsprozessmodellen. Nicht selten stehen zur Anforderungserhebung daher Modelle zur Ver- fügung, die ursprünglich eine andere Aufgabe hatten (etwa die Prozessdokumentation oder die Un- terstützung einer internen Schulung). Das hat zur Folge, dass solche Modelle unter Umständen wesentliche Informationen nicht enthalten, da selten vorkommende Abläufe, Fehlerzustände und Ausnahmen bewusst nicht modelliert wurden. Aufgabe bei der Anforderungsanalyse ist es, solche Modellierungslücken zu erkennnen und das Stellen geeigneter Nachfragen zu unterstützen. In diesem Beitrag wird die Idee eines Werkzeugs vorgestellt, das einige typische Indikatoren für fehlende Informationen im Modell automatisch findet und die erforderlichen Nachfragen formuliert. Dies kann Anforderungsanalytiker bei der Arbeit mit Geschäftsprozessmodellen unterstüzten.
