- ZeitschriftenartikelAutomatic Generation of Glossaries for Process Modelling Support(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 6, Nr. 1, 2011) Peters, Nicolas; Weidlich, MatthiasProcess models are often used for human to human communication. Besides other aspects, e.g., the chosen modelling notation or the model layout, the labelling has a strong influence on the understandability and, therefore, quality of a model. Consequently, labels should be reused and aligned across different process models. In order to support these goals, a glossary might be applied in the course of modelling. In this article, we argue that such a glossary can be generated automatically from the labels of an existing process model collection, e.g., a reference model. We introduce an approach for such a glossary generation that takes additional information on structural as well as control flow aspects into account. The applicability of our approach is illustrated by means of two case studies. Based thereon, we also report on findings regarding the appropriateness of the chosen structural and behavioural aspects.
- ZeitschriftenartikelBalancing Customer Requirements and IT Service Standardisation - A Procedural Reference Model for Individualised IT Service Agreement Configurations(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 6, Nr. 2, 2011) Brocke, Henrik; Uebernickel, Falk; Brenner, WalterIT service providers are increasingly urged to stringently align their service portfolio with the IT support of their customers’ business processes. Consequently, both IT expenses and its strategic contribution to value creation are expected to become subject to heightened transparency. Yet, in order to allow for standardised on-demand service request processing within the meaning of IT industrialisation, these services appear too adapted to individual customer needs, particularly as they are subject to continuous changes in business requirements. In order to address this issue, a three-phase procedural model of IT service agreement configuration is introduced: IT services thus remain transformable and configurable via predefined complementary services which are selected by configuring a customer’s individual service directory. In addition, the reutilisation of modular commitments in order to compose service specifications aims to maintain standardised IT operations. Serving as a procedural reference model, these configuration phases are introduced in detail regarding activities, roles, techniques and data structure as developed and implemented in Action Research cooperation with two IT providers.
- ZeitschriftenartikelChecking the Semantic Correctness of Process Models - An Ontology-driven Approach Using Domain Knowledge and Rules(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 6, Nr. 3, 2011) Fellmann, Michael; Hogrebe, Frank; Thomas, Oliver; Nüttgens, MarkusThis paper presents an ontology-driven approach that aims at ensuring the semantic correctness of semiformal process models. Despite the widespread use of these models in research and practice, their semantic correctness is still a challenging issue. We suggest an ontology-driven approach making use of background knowledge encoded in formal ontologies and rules. In the first step, we develop a model for ontology-based representation of process models. In the second step, we use this model in conjunction with rules and machine reasoning for applying checks concerning the semantic correctness. We apply our approach using real-life administrative process models taken from a capital city.
- ZeitschriftenartikelA Conception of a Presentation Development and Management System Featuring ‘Smart Slides’(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 6, Nr. 1, 2011) Frank, UlrichThis paper presents a conception of a presentation development and management system (PDMS) and a related process model that guides its adequate use. It is inspired by the idea to replace certain graphical representations on presentation slides with diagrams that are constructed with domain-specific modelling languages (DSML) and corresponding model editors. The PDMS features an extensible set of graphical DSML that originate in a method for enterprise modelling. They provide the conceptual foundation for graphical representations that include domain-specific semantics. Specifying DSML and generating code for corresponding model editors is supported by an integrated metamodelling environment. Various DSML can be combined to create interactive, multi-language diagrams. The embedded semantics enables versatile machine analysis and allows for interactive slides. An accompanying compound architecture allows for integrating interactive diagrams with slides that contain traditional types of content such as text or drawings. Furthermore, it provides the conceptual foundation for storing presentations in a steadily growing common repository of organisational knowledge, thereby promoting reuse on various levels of abstraction.
- ZeitschriftenartikelConceptual Development of Industrial Product-Service Systems - A model-based Approach(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 6, Nr. 2, 2011) Sadek, Tim; Köster, MatthiasThe increasing competitiveness of today’s globalised economies and changing customer requirements prompt manufacturers to provide integrated product and service solutions, referred to as Industrial Product-Service Systems (IPS²). An IPS² constitutes a customised solution, whereas providing performance is set above the purchase of a mere technical product. It can comprise any combination of product and service shares. Once such an offer is planned, the IPS² concept development phase generates principle solutions that meet customerspecific requirements. This article presents a model-based methodology to support an IPS² designer during the process of generating IPS² concepts in the early phase of IPS² development. This methodical framework and the modelling approach for conceptual IPS² development has been implemented as a computer-aided tool and has been evaluated by solving a typical IPS² issue.
- ZeitschriftenartikelDetecting Common Errors in Event-Driven Process Chains by Label Analysis(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 6, Nr. 1, 2011) Gruhn, Volker; Laue, RalfIn this article, we discuss several classes of error patterns that can frequently be found in Event-Driven Process Chains (EPC). Instances of these patterns can be detected by using a pattern-matching approach: The model is translated into a set of Prolog rules and potential modelling problems are located by querying the Prolog fact base for certain problem patterns. In particular, this article presents patterns for problems that can be detected by analysing the labels of events and functions in EPCs. To make reasoning about the contents of the labels possible, the labels are transformed into a normal form. By taking synonyms, antonyms and negating words (no, not) into account, we locate labels that contradict each other. This leads to the detection of some classes of errors like modelling of an event and its negation occurring at the same time. Our method has been applied to 1253 EPC models in German language. We have been able to detect a large number of errors in those models that remain undetected using traditional approaches for EPC validation.

- ZeitschriftenartikelPricing of Value Bundles - A Multi-Perspective Decision Support Approach(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 6, Nr. 2, 2011) Becker, Jörg; Beverungen, Daniel; Knackstedt, Ralf; Müller, OliverValue bundles are compositions of physical goods and related value-added services that are put together to solve customer problems. Pricing value bundles constitutes a complex decision problem, since it requires the consideration of three perspectives: From the point of view of the provider, the available price corridor is limited downward by the costs for engineering, marketing and delivering a value bundle. From the customer’s point of view, the upper limit of the price corridor is imposed by the expected customer value and corresponding willingness to pay. From a competitive perspective, the upper limit of the price corridor is marked by the price of a comparable competitor’s offer. To provide companies with sound decision support, an integrated multi-perspective modelling language that accounts for all three perspectives simultaneously is presented. Based on the developed modelling language, an integrated decision support tool, i.e., the pricing workbench, has been designed.
