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.

Seminal Contribution to the Information Systems Engineering Field

A great honor for the researchers! The paper entitled “Change Patterns and Change Support Features in Process-Aware Information Systems”, which had been originally presented at the CAiSE'07 conference in Trondheim, was selected as one of the most seminal works published in the last 25 years in the prestigious CAiSE conference series. The paper has been co-authored by Barbara Weber, Manfred Reichert and Stefanie Rinderle-Ma and now been re-printed in a Springer book.

Seminal Contribution

The following book was presented at the CAiSE’13 conference in Valencia in June this year. Manfred Reichert was also invited to the “25 years of CAiSE” panel to give a statement about the selected work.

Bubenko, J.; Krogstie, J.; Pastor, O.; Pernici, B.; Rolland, C.; Sølvberg, A. (Eds.) Seminal Contributions to Information Systems Engineering - 25 Years of CAiSE, Springer, 2013


In 2013, the International Conference on Advanced Information Systems Engineering (CAiSE) has turned 25. Initially launched in 1989, for all these years the conference has provided a broad forum for researchers working in the area of Information Systems Engineering. To reflect on the work done so far and to examine prospects for future work, the CAiSE Steering Committee decided to present a selection of seminal papers published for the conference during these 25 years and to ask their authors, all prominent researchers in the field, to comment on their work and how it has developed over the years. The decision was based on the impact of the paper on the information systems engineering field, the number of citations received, and the technical quality.

The DBIS researchers are pleased that their work on process change patterns has been included in this prestigious book, which again acknowledges the high impact and international visibility of DBIS research. Also the journal article Change Patterns and Change Support Features - Enhancing Flexibility in Process-Aware Information Systems. Data and Knowledge Engineering, 66(3): 438-466, which extends the work presented in the CAiSE’07 paper, has been frequently cited, thus further illustrating the impact of DBIS research. In fact, this extended article on process change patterns constitutes the most cited article of the Data & Knowledge Engineering Journal in the last five years.

Reflections on our work on process change patterns as well as their evolution and impact can be found in the following paper:

User Recommendations for the Optimized Execution of Constraint-Based Processes

DKEUser Recommendations for the Optimized Execution of Business Processes by Irene Barba, Barbara Weber, Carmelo Del Valle, and Andres Jimenez-Ramirez got accepted in Elsevier's Data and Knowledge Engineering journal. The article suggests an approach for assisting users during the execution of constraint-based processes (see Chapter 12 of the book) through recommendations on next possible execution steps.

Abstract. In order to be able to flexibly adjust a company's business processes (BPs) there is an increasing interest in flexible Process-Aware Information Systems (PAISs). This increasing flexibility, however, typically implies decreased user guidance by the PAIS and thus poses significant challenges to its users. As a major contribution of this work, we propose a recommendation system which assists users during process execution to optimize performance goals of the processes. The recommendation system is based on a constraint-based approach for planning and scheduling the BP activities and considers both the control-flow and the resource perspective. To evaluate the proposed constraint-based approach different algorithms are applied to a range of test models of varying complexity. The results indicate that, although the optimization of process execution is a highly constrained problem, the proposed approach produces a satisfactory number of suitable Solutions.

bpmuy-logoTitle. Enabling Flexibility in Process-aware Information Systems: Methods and Technologies

Abstract. The economic success of enterprises increasingly depends on their ability to react to changes in their environment in a quick and flexible way. Companies have heretofore identified business agility as a competitive advantage to address business trends like increasing product and service variability and faster time-to-market and process-aware information systems (PAISs) are getting increasingly popular. In contrast to traditional information systems, PAISs rely on an explicit description of business processes. In response to the need for flexible and easily adaptable PAIS, different aradigms and technologies for realizing flexible PAIS have emerged. Examples include adaptive, constraint-based and data‐driven approaches. This talk will present a comprehensive review of the challenges that exist for flexible PAIS, and it will give insights into concepts, paradigms and technologies for their realization. Flexibility issues are discussed along the phases of the process lifecycle (i.e., design, modeling, configuration, execution, monitoring, and evolution). Main focus of the talk will be flexibility requirements and enabling technologies for pre‐specified processes, the currently predominant paradigm for supporting business processes.

Overcoming Challenges of Reuse in Large Collections of Process Models

The increasing adoption of Process-Aware Information Systems (PAIS), together with the reuse of process knowledge has resulted in process model repositories with large collections of process models. Understandability and maintainability of the process models in the repository are preconditions for their successful reuse. However, industrial process models display a wide range of quality problems impeding their comprehensibility and consequently hampering their maintainability and reuse. Literature reports, for example, error rates between 10% and 20% in industrial process model collections. Moreover, non-intention-revealing or inconsistent naming, redundant process fragments, and overly large and unnecessarily complex process models are typical quality problems which can be observed in existing process model collections. These problems have resulted in vivid research with the goal of obtaining a better understanding of factors influencing the quality of process models as well as techniques fostering their understandability and maintainability.

For obtaining high quality models it is essential to understand the factors which are influencing the quality of process models, but also the way how process models are created. This challenge can be approached by taking a cognitive perspective and by analyzing the process of creating and maintaining process models (in addition to the modeling artifacts created). In part I of the talk I will report on some of the findings obtained so far, discuss their implications for the reuse of process models, and outline future research directions.

Part II of this keynote covers different techniques for fostering understandability as well as maintainability of process models which were developed in our group like test driven modeling, literate process modeling, but also techniques for the refactoring of large collections of process models. Again implications for the reuse of process models will be discussed.

BPM'12 Tutorial on Large Process Models and Process Model Collections

In the context of the BPM 2012 conference conference, which took place from September 5-7 in Tallinn, Estonia, Manfred Reichert (DBIS), Barbara Weber (University of Innsbruck) and Victoria Torres Bosch (University of Valencia) organized a tutorial on large process models (i.e., large process model trees or complex inter-related process structures) and large process model collections. The tutorial discussed the challenges that arise both in respect to the handling of large process models and the management of large collections of process models (with related process variants). As a motivational backbone, large process models and process model collections from the automotive industry and the healthcare domain were presented. Overall the tutorial, which was attended by more than 40 participants from the international research community, was a great success! The tutorial also addressed several of the topics described in detail in our book, e.g., process model refactoring (Chapter 9), process variant support and process configuration (Chapter 5), and data-driven process structures (Chapter 13).
