Keynote 1: Process Abstraction, Choreographies, and Design

by Mathias Weske

Abstract. The explicit representation of business processes and their enactment are important aspects of information systems design. In this talk, current trends in business process management are highlighted. Based on fundamentals of process orchestrations, we start by discussing business process abstraction. This stream of work was conducted in cooperation with a large German health insurance company. While business processes have so far mainly focused on procedures within organizations, processes involving multiple partners receive increasing attention. Based on research done by the scientific community, the BPMN standard has introduced specific diagram types to capture process choreographies. Finally, a novel approach to process model elicitation is discussed. This work was conducted in a joint project with Stanford University. It tries to increase involvement of domain experts in the modeling process and uses the concept of tangibility to achieve this. The talk concludes with a brief introduction of the BPM Academic Initiative, which aims at supporting process technology in academic research and teaching.

Professor Dr. Mathias Weske is chair of the business process technology research group at Hasso Plattner Institute of IT Systems Engineering at the University of Potsdam, Germany. His research interests include business process management, process choreographies, process modeling methodologies, and service oriented computing. Dr. Weske has published twelve books and over 150 scientific papers in journals and conferences. He is on the steering committee of the BPM conference series, a member of ACM, IEEE, and GI. Dr. Weske has published a textbook on business process management. He is a co-founder of Berlin-based software company Signavio, chairperson of the Business Process Management Academic Initiative and the author of a massive online course on Business Process Modeling and Analysis hosted at

Keynote 2: The Challenges of Modeling and Evolving Cross-Organizational Processes

by Manfred Reichert

Abstract. The economic success of companies more and more depends on their ability to rapidly implement new business processes as well as to flexibly adapt existing processes to changes in their environment. While modeling and flexibility issues of internal company processes are well understood nowadays, the controlled change of the interactions between partner processes in a collaborative setting (i.e., cross-organizational process) has not been sufficiently considered so far. If one partner changes its internal process in an uncontrolled manner, inconsistencies or errors regarding its interactions with the other partners might occur. Additionally, compliance of the changed cross-organizational process and the partner interactions, respectively, with imposed regulations and laws need to be guaranteed. As a particular challenge,the private parts of the internal partner processes are hidden to the other partners and hence are unknown to them.
This keynote will discuss research challenges to be tackled in this context. Further, it will give insights into selected results from the C3Pro research project which aims to enable change and compliance for cross-organizational processes.

Professor Dr. Manfred Reichert holds a PhD in Computer Science and a Diploma in Mathematics. Since 2008 he has been appointed as full professor at the University of Ulm, where he is director of the Institute of Databases and Information Systems. Before, he was associate professor at the University of Twente in the Netherlands and a member of the management board of the Centre for Telematics and Information Technology, which is one of the largest academic ICT research institutes in Europe. Manfred’s research interests include business process management (e.g., process flexibility, process lifecycle management, and object-centric processes), service-oriented computing (e.g., service interoperability, mobile services, and service evolution) and e-health. Manfred has been PC Co-chair of the BPM’08, CoopIS’11, EMISA’13 and EDOC’13 conferences, and General Chair of the BPM’09 and EDOC’14 conferences. Recently, he co-authored a Springer book on process flexibility.

Towards a Foundational Framework for Developing and Testing Inter-organizational Business Processes

by Philip Langer, Stefan Sobernig, and Gustaf Neumann

Abstract. Modeling and analyzing inter-organizational business processes is complicated substantially by heterogeneous process-modeling languages (e.g., surface vs. analysis languages) as well as by their inherent properties of loose coupling and local control (views). On top, multiple concerns must be addressed when modeling inter-organizational business processes, such as process data, behavior, distribution, and resources management. We believe that more research effort is needed towards establishing a language-oriented foundation for modeling inter-organizational business processes. This paper lays out one direction of language engineering towards this goal, collects generic and specific requirements on a language framework for IOPs, and discusses them tentatively.

Challenges of Testing Business Process Models in Intra- and Inter-Organizational Context

by Stefan Mijatov and Tanja Mayerhofer

Abstract. In order to address the issue of complexity and changeability of business processes, as well as of the information technology used to implement these processes, business process models are used. As business process models become central artifacts, validating their functional correctness becomes essential. Many approaches exist, that deal with validating the functional correctness of business process models in an intra-organizational context (i.e., the process is controlled and maintained by one business entity). However, in today’s highly globalized business world, business processes are usually carried out by several business partners, each providing their own services to accomplish more complex inter-organizational business processes. This induces new challenges to validating the functional correctness of business processes based on models. In this paper we provide an overview of existing approaches to analyze business process models in both intra- and inter-organizational context and discuss arising challenges.
