“…However, little quantitative research has 3 been reported on the actual use of conceptual modeling in practice [1]. over, literature typically discusses and analyses languages rather than evalu- 5 ating enterprise models at a larger scale (i.e., beyond "toy examples"). A fun-6 damental problem in this context is that large enterprise models are in general 7 not accessible for research as they represent valuable company knowledge that 8 enterprises do not want to reveal.…”

Up to now there is neither data available on how many errors can be expected in process model collections, nor is it understood why errors are introduced. In this article, we provide empirical evidence for these questions based on the SAP reference model. This model collection contains about 600 process models expressed as Eventdriven Process Chains (EPCs). We translated these EPCs into YAWL models, and analyzed them using the verification tool WofYAWL. We discovered that at least 34 of these EPCs contain errors. Moreover, we used logistic regression to show that complexity of EPCs has a significant impact on error probability.

“…In [6], authors present a workflow management application that collects information-rich business process documents, stores them in an organizational memory system, and informs staff and management in various situations. In fact, they have implemented an integrated workflow-centric knowledge management solution using R/3, SAP Business Workflow, and IXOS-ARCHIVE at a large German media company.…”

This paper investigates the relation between workflow systems and corporate memory. More clearly, it emphasizes how workflow systems facilitate the achievement of corporate memory. It also proposes a classification for corporate memory in the context of workflow systems. This classification defines two types of corporate memory; each providing a distinct knowledge contributing to decision making. The study has been done based on a real case study at the Centre Régional d'Investissement (CRI) in Marrakech, Morocco. This centre is entrusted to accompany investors and facilitate all administrative procedures for them.

“…Furthermore, we use the term inconsistencies to refer to a mismatch of model and specification. It has been described in [92,211] and is referred to in many research papers (see [127,235,281,362,427]). Generally speaking, error detection is related to both verification and validation [436, p.445].…”

“…Reference modeling refers to the documentation of generic business operations in a model such as service processes in the telecommunications sector, for example. The SAP Reference model had a huge impact with several researchers referring to it in their publications (see [473,235,127,362,281,427,415]) as well as motivating the creation of EPC reference models in further domains including computer integrated manufacturing [377,379], logistics [229] or retail [52]. The roots of reference modeling can be traced back to the Kölner Integrationsmodell (KIM) [146,147] that was developed in the 1960s and 1970s.…”

PrefaceBusiness process modeling plays an important role in the management of business processes. As valuable design artifacts, business process models are subject to quality considerations. The absence of formal errors such as deadlocks is of paramount importance for the subsequent implementation of the process. This book develops a framework for the detection of formal errors in business process models and for the prediction of error probability based on quality attributes of these models (metrics). We focus on Event-driven Process Chains (EPCs), a widely used business process modeling language due to its extensive tool support. The advantage of this focus is firstly that the results of this book can be directly translated into process modeling practice. Secondly, there is a large empirical basis of models. By utilizing this large stock of EPC model collections, we aim to bring forth general insights into the connection between process model metrics and error probability. In order to validate such a connection, we first need to establish an understanding of which model attributes are likely connected with error probability. Furthermore, we must formally define an appropriate notion of correctness that answers the question of whether or not a model has a formal error. As a prerequisite to answering this question, we must define the operational semantics of the process modeling language formally. ContributionsThis book presents a precise description of EPCs, their control-flow semantics and a suitable correctness criterion called EPC soundness. Furthermore, we identify theoretical arguments on why structural metrics should be connected with error probability and provide an empirical validation of this connection. To be more concise, this book provides the following technical contributions.Formalization of the OR-join: The semantics of the OR-join have been debated for more than a decade. Existing formalizations suffer from either a restriction of the EPC syntax (see [78,247,238,4,101]) or from non-intuitive behavior (see [325,218,11,465]). In Chap. 2, we formalize the EPC semantics concept as proposed elsewhere [267]. In comparison to other approaches this novel formalization has the advantage of not being restricted to a subset of EPCs. Moreover, VIII Preface it provides intuitive semantics for blocks of matching OR-splits and joins since they cannot deadlock. As a proof of concept, we implemented a plug-in for ProM that calculates the reachability graph. In this way, this novel semantics definition contributes to research on the specification of business process modeling languages. Verification of process models with OR-joins and multiple start and end events:Verification techniques for process models with OR-joins and multiple start and end events suffer from one of two problems: Firstly, they build on an approximation of the actual behavior, e.g., by considering a relaxed notion of soundness [101], by involving user decisions [109] or by approximating relaxed soundness with invariants [440]. Therefore, they d...
