The dissertation contributes the integration of process management technology with smart mobile devices. It examines how specific process activities can be executed on smart mobile devices in a robust and context sensitive fashion. Furthermore, the dissertation examines what additional challenges arise when executing processes on mobile devices when compared to their execution on stationary systems. A concrete framework for modeling mobile activities in a process environment, as well as their robust and context sensitive execution is presented. The framework was validated with a thorough prototypical implementation as well as multiple studies.

Time patterns for process-aware information systems

New article online now: "Time patterns for process-aware information systems" by Andreas Lanz, Barbara Weber and Manfred Reichert. More information:


Companies increasingly adopt process-aware information systems (PAISs) due to their promising perspectives for improved business process support. Although the proper handling of temporal constraints is crucial in this context, existing PAISs vary significantly regarding their support of the temporal perspective of a business process. To make PAISs comparable with respect to their ability to deal with temporal constraints and to facilitate the development of a time-aware PAIS, this paper suggests 10 time patterns. All patterns are based on empirical evidence we gathered in case studies. Additionally, they are validated through a systematic literature review. Based on the time patterns, we then provide an in-depth evaluation of selected PAISs and academic approaches. Altogether, the 10 time patterns will not only facilitate the selection of technologies for realizing time- and process-aware information systems but can also be used as reference for implementing time support in PAISs.

In her PhD project, Vera Künzle developed the PHILharmonic Flows framework, which enables object-aware process management in a very flexible and comprehensive manner. In particular, the framework not only provides a highly original process modeling approach, but also establishes a well-defined operational semantics enabling the robust execution of object- and process-aware applications as well as the automatic and dynamic generation of end-user components for them (e.g., overview tables and user forms). Overall, a holistic framework integrating data, functions, processes and users offers promising perspectives in order to overcome the numerous limitations of contemporary business process management systems. PHILharmonic Flows hence provides an important contribution towards the realization of more flexible process management technology in which daily work can be done in a more natural and flexible way.

Keynote at EDOC’14: Investigating the Process of Process Modeling: Towards an In-depth Understanding of How Process Models are Created


Barbara will give a keynote at EDOC’14, which is organized by Manfred Reichert and his team of the university of Ulm. The keynote on gaining and in-depth understanding of the process of process modeling will be held on September 5th. Don’t miss it! Details can be found subsequently.

Abstract. Business process models have gained significant importance due to their critical role for managing business processes. Still, process models display a wide range of quality problems. For example, literature reports on error rates between 10% and 20% in industrial process model collections. Most research in the context of quality issues in process models puts a strong emphasis on the product or outcome of the process modeling act (i.e., the resulting process models), while the process followed for creating process models is only considered to a limited extent.

2014 08 15 Weber Keynote

The creation of process models involves the elicitation of requirements from the domain as well as the formalization of these requirements as process models. In this presentation the focus will be on the formalization of process models, which can be considered a process by itself­—the process of process modeling (PPM). In particular, this presentation will discuss how the PPM can be captured and analyzed. For this, it will present a specialized modeling environment, which logs all interactions of the process modeler with the modeling environment, thus, providing the infrastructure to investigate the PPM. The presentation will also shed light on the way how process models are created, present different behavioral patterns that can be observed, and discuss factors that influence the PPM, e.g., modeler-specific factors like domain knowledge or process modeling competence and task-specific factors. In addition, the presentation will provide an outline on how methods like eye movement analysis, think aloud, or the analysis of bio-feedback (e.g., heart rate variability) might enable even deeper insights into the PPM.

IEEE Conference on Enterprise Computing at Ulm University

Helsinki, Beijing, and Vancouver in the previous years, Adelaide next year, and this year? Ulm! More than 150 experts from over 25 countries will travel to Ulm between 1st and 5th September 2014 in order to attend the Opens external link in new window18th International IEEE EDOC Conference.

Regardless of whether an industrial company, a service provider or the public sector – every organization has to embrace state-of-the-art information and communication technology (ICT) to run its business successfully these days. In this context, Enterprise Computing comprises all information systems that ensure the smooth operation of intra- and inter-organizational business processes. Thereby, information-processing technologies come into play as well as methodologies and efficient approaches to develop and run those technologies.

The EDOC conference series provide the key forum for researchers, decision makers, enterprise architects, solution designers, and practitioners in the field of Enterprise Computing. The world's largest association of technical professionals Opens external link in new windowIEEE has been sponsoring the series since its foundation in 1997.  “We are regarded as one of the top research groups in the field of Enterprise Computing. So, bringing this international top conference to Ulm was a logical step at the end,” Opens internal link in current windowProf. Dr. Manfred Reichert, designated director of the Opens internal link in current windowInstitute of Databases and Information Systems, said.

This year’s EDOC conference in Ulm focuses on a late-breaking topic that even companies in the local area have to deal with in upcoming decades: the rapidly growing information overload in the information age as well as its implications on business processes, products and services. “Big Data will affect companies as much as the Internet did at end of 1990s. A direct and fast access to huge amounts of data including the smart analysis as well as the automatic extraction of information and knowledge will offer entirely new opportunities to companies. However, at the very same time, companies’ IT systems face tremendous challenges regarding the proper processing of big data, no matter whether it is unstructured data from the Internet or structured one from sensors built in production machines,” Prof. Reichert explains.

The EDOC 2014 organizers are very glad that they were able to convince Opens external link in new windowthree distinguished speakers holding the conference keynotes. One of Europe’s most famous computer scientists, Opens external link in new windowProf. Wil van der Aalst from the Technical University Eindhoven (The Netherlands), who is a member of the Royal Holland Society of Sciences and Humanities and the Academy of Europe, will give a presentation about the role of Big Data in the analysis and optimization of business processes on Wednesday. In the following days, Dr. Heiko Ludwig from the IBM Research Center in San Jose/USA and Prof. Dr. Barbara Weber from the University of Innsbruck will give talks about specialized topics in the area of Cloud Computing and Business Process Management.

Regarding the keynotes it is to be finally emphasized that students from Ulm University are allowed to attend the keynotes for free (after a registration on the website). The local EDOC 2014 organizers – Prof. Dr. Manfred Reichert, Opens internal link in current windowNicolas Mundbrod and Opens internal link in current windowRüdiger Pryss – thereby want to strengthen the important interplay between teaching and research. Further information about the conference, the keynote speakers as well as the opportunity to quickly register for the conference are available on the official website Opens external link in new window
