BPMN 2.0 is a standard for business processes modeling. Besides praise for this notation, there is definitely some criticism. With a practical case study it is analyzed whether positive and negative associations with BPMN play a role in actual practical use. With the help of a group of students a practical case study is carried out, analyzing various BPMN products. This paper summarizes the results and findings from this case study.

Business process management is a widely used tool in practice nowadays. There are methodologies for business process management like EPC, BPMN 2.0, or S-BPM with different focuses and strengths. The subject-phase matrix S-PM follows the subject oriented paradigm of S-BPM focusing on subjects as the central concept. At the same time, S-PM provides a complete and clear overview of the overall process of all subjects. For this methodology a meta model is provided and the implementation of a web based modeling tool is described.

Security and privacy in computer systems is a major issue and it is hard to find a good compromise between necessary protection and desirable open access to the internet. We propose a subject-oriented approach to computer security analysis in order to comply with the users’ needs.

The project STERN aims to support German notaries to implement a secure electronic communication structure involving numerous governmental and private parties. Communication is an integral part of the business process in a notary's office and has to be handled economically. fast, easy. trustworthy. and secure. Therefore, a careful analysis of the notarial work flows is in order. A variety of process modeling techniques is explored to identify their suitability for distributed and communication intensive work flows. To identify the best modeling approach. evaluation criteria were established. Some typical tasks of the application domain were modeled with the different methods and finally presented to and discussed with notaries. The results of this study are presented and an outlook on the further course of the project is given.

Dieser Artikel befasst sich mit dem Stand der IV-Beratung für Notariate und zeigt dabei Moden und Trends in diesem Bereich auf. Es wird ein Überblick gegeben, welche IV-Strukturen für die interne und externe Verfahrensabwicklung im Notariat als Teil des E-Governments existieren und welche in Zukunft eingeführt werden. Es wird gezeigt, auf welche Art die Notariate dabei durch IVBeratung unterstützt werden und inwieweit Notare bei ihrer Tätigkeit selbst als IVBerater auftreten. Es wird ein Referenzmodell für die speziellen Bedürfnisse der notariellen Kommunikation vorgestellt und dargestellt, wie dieses als Basis für die IV-Beratung zum Einsatz kommen kann. Diese Themen sind Teilbereiche des Forschungsprojekts STERN (Sichere Teilnahme am elektronischen Rechtsverkehr für Notare) an der Hochschule Deggendorf. Die gezeigten Entwicklungen werden abschließend zusammengefasst und diskutiert.
