We've gotten great feedback from our clients that these are effective illustrations too. The crayon styling makes it clear that they're just mockups so people don't poke at the style aspects of the design. We use Pencil with the crayon-styled stencils to make quick mockups. Best practice to draw/describe UIs in plain text? I wouldn't use text to illustrate a GUI.Furthermore, the authors were able to verify the conformity of extensions as they were published after the introduction of the BPMN extension mechanism by the Object Management Group. To the best of the authors’ knowledge, the literature review is the only one that evaluates and compares all BPMN extensions over the last four years, based on several criteria covering different aspects. On the other hand, the authors have observed several shortcomings and suggested recommendations for addressing them. The representation of the results in the form of tables and graphs allowed the authors to deduce several positive points on the extensions as their demonstration through concrete examples. After the collection and filtering of papers, 52 extensions were retained to be thoroughly examined and compared according to a set of criteria including objective, targeted domain, conformity to the extension mechanism, demonstration, implementation, etc. The purpose of this paper is to present a literature review that aims to determine the current state of the art of BPMN extensions and identify the gaps that should be filled in this research area.įor a comprehensive and effective analysis, a systematic literature review was conducted. Then we propose the prototypes for these two smart systems in order to carry out a set of extensive experiments illustrating the efficiency and effectiveness of our work.īusiness Process Model and Notation (BPMN) is a generic language that is often extended by researchers, either for dealing with processes of specific domains or for improving the language itself. Third, we model, by using the proposed BPMN 2.0 extension, smart autistic child and coronavirus disease 2019 monitoring systems. Second, we present a new IoT-fog-cloud based architecture, which (i) supports the distributed inter and intralayer communication as well as the real-time stream processing in order to treat immediately IoT data and improve the entire system reliability, (ii) enables the multiapplication execution within a multitenancy architecture using the single sign-on technique to guarantee the data integrity within a multitenancy environment, and (iii) relies on the orchestration and federation management services for deploying BP into the appropriate fog and/or cloud resources. The proposed extension takes into consideration the heterogeneous IoT and non-IoT resources, resource capacities, quality of service constraints, and so forth. In this article, first, we propose a business process model and notation (BPMN) extension to enable the Internet of Things (IoT)-aware business process (BP) modeling. However, this brings many challenges shall be overridden when distributing a real-time stream processing, executing multiapplication in a safe multitenant environment, and orchestrating and managing the services and resources into a hybrid fog/cloud federation. Making resources closer to the user might facilitate the integration of new technologies such as edge, fog, cloud computing, and big data.
