- ZeitschriftenartikelA Study on the Usage of the BPMN Notation for Designing Process Collaboration, Choreography, and Conversation Models(Business & Information Systems Engineering: Vol. 66, No. 1, 2024) Compagnucci, Ivan; Corradini, Flavio; Fornari, Fabrizio; Re, BarbaraBeing widely accepted by industries and academia, Business Process Model and Notation (BPMN) is the de facto standard for business process modeling. However, the large number of notation elements it introduces makes its use quite complex. This work investigates the usage of the BPMN notation by analyzing 54,500 models harvested from seven online collections. The study considers different model types introduced by the standard, such as process collaboration, choreography, and conversation. The analyses focus on the syntactic dimension of BPMN, investigating the usage of BPMN elements and their combinations. Syntactic violations of the standard, and of good modeling practices, are also investigated as well as possible relations with BPMN elements and modeling tools. The results of the study can guide further activities of educators, practitioners, researchers, and standardization bodies.
- KonferenzbeitragA Collaborative Approach to Public Administrations Inter-organizational Business Processes Modelling(Electronic Government and Electronic Participation - Joint Proceedings of Ongoing Research of IFIP EGOV and IFIP ePart 2019, 2013) Cognini, Riccard; Falcioni, Damiano; Polzonetti, Alberto; Re, BarbaraThe paper presents a collaborative approach to the definition of interorganizational Business Processes. Applying the proposed modeling approach multiple organizations can easily reconcile local and global views. In particular, the modeling phase is based on BPMN 2.0 standard notation and it proceeds according to the following steps: (i) all organizations collaboratively derive a communication view of the process, (ii) a local communication view is automatically deduced for each organization, and (iii) each organization models its own private process taking into account foreseen local communications. The approach is supported by a user-friendly and web based tool named HawkEye that has been successfully applied to real scenarios in the e-government domain.
