- KonferenzbeitragModel-based competency-oriented business process analysis(Modellierung betrieblicher Informationssysteme (MobIS 2008), 2008) Leyking, Katrina; Angeli, Ralf; Loos, Peter; Nüttgens, Markus; Turowski, Klaus; Werth, DirkTraditionally, business process analysis is primarily concerned with the identification of structural weaknesses, inefficient capacity utilization or IT deficiencies. Despite this well-founded knowledge about process performance, and despite the increasingly recognized relevance of human capital for business performance, business process analysis efforts rarely touch human resources - except for downsizing or layoffs. The objective of this paper is to extend traditional business process modelling and business process simulation by competency requirements and their impact on process performance. By doing so, business process performance can be improved through the integration of competency requirements into process design. The approach addresses the need to derive competency requirements from business processes in order to facilitate the alignment of employee competency profiles with business roles (staffing) as well as the effective closure of business-relevant competency gap through tailored learning processes (business-driven personnel development).
- KonferenzbeitragDesigning and utilising business indicator systems within enterprise models – Outline of a method(Modellierung betrieblicher Informationssysteme (MobIS 2008), 2008) Frank, Ulrich; Heise, David; Kattenstroth, Heiko; Schauer, Hanno; Loos, Peter; Nüttgens, Markus; Turowski, Klaus; Werth, DirkThe design of effective indicators and indicator systems requires a profound understanding of the relevant business context. Numerous relations and dependencies within an indicator system exist, which need to be analysed thoroughly: Many relations are based on implicit assumptions or sometimes not known by the management at all. This is of particular relevance for business success, since improperly used indicator systems may lead to `dysfunctional effects' like opportunistic behaviour. This paper outlines a method for designing and utilising indicator systems. It fosters a convenient and consistent definition and interpretation of indicator systems. Furthermore, it serves as a conceptual foundation for related performance management systems, such as dashboard systems.
- KonferenzbeitragTowards simulation-supported enterprise architecture management(Modellierung betrieblicher Informationssysteme (MobIS 2008), 2008) Buckl, Sabine; Matthes, Florian; Renz, Wolfgang; Schweda, Christian M.; Sudeikat, Jan; Loos, Peter; Nüttgens, Markus; Turowski, Klaus; Werth, DirkEnterprise architecture management is based on a holistic view on the enterprise addressing business and IT aspects in an integrated manner. EA management is a process to manage the complexity of the overall architecture and to improve the alignment of business and IT. In order to achieve these goals, it is necessary but not sufficient to manage the static complexity that arises from dependencies between the elements of the EA, like goals, organizational units, business processes, business applications, and IT infrastructure elements. Performance, stability, and scalability can only be analyzed, modeled, and controlled, if static EA models are enriched by appropriate abstractions to capture the dynamic complexity of the EA understood as a socio-technical system of interacting (sub-)systems. This article identifies possible techniques to address dynamic complexity in EA. The potential benefits of system simulations are discussed and the derivation of apropriate simulation models is exemplified. A key observation is the fact that EA management is a iterative evolution process, where each iteration only changes a small fraction of the EA. It is therefore possible to automatically derive model parameters required for the simulation of the future architectures from an analysis of the dynamics of the current architecture.
- KonferenzbeitragAn engineering approach to enterprise architecture design and its application at a financial service provider(Modellierung betrieblicher Informationssysteme (MobIS 2008), 2008) Aier, Stephan; Kurpjuweit, Stephan; Schmitz, Otto; Schulz, Jörg; Thomas, André; Winter, Robert; Loos, Peter; Nüttgens, Markus; Turowski, Klaus; Werth, DirkIn analogy to classical engineering disciplines, this contribution discusses characteristics and requirements of an engineering approach to enterprise architecture design and proposes components and a top-level structure of an approach to address these requirements. The proposed components can partially be realized by existing work; partially they lay out the research path towards a mature engineering discipline of EA design. Core components of the proposed approach have been applied and evaluated at Deutsche Leasing AG, a globally operating financial service provider based in Germany.
- KonferenzbeitragOn the choice between graph-based and block-structured business process modeling languages(Modellierung betrieblicher Informationssysteme (MobIS 2008), 2008) Kopp, Oliver; Martin, Daniel; Wutke, Daniel; Leymann, Frank; Loos, Peter; Nüttgens, Markus; Turowski, Klaus; Werth, DirkThe most prominent business process notations in use today are BPMN, EPC and BPEL. While all those languages show similarities on the conceptual level and share similar constructs, the semantics of these constructs and even the intended use of the language itself are often quite different. As a result, users are uncertain when to use which language or construct in a particular language, especially when they have used another business process notation before. In this paper, we discuss the core characteristics of graph-based and block-structured modeling languages and compare them with respect to their join and loop semantics.
- KonferenzbeitragBusiness process compliance checking: Current state and future challenges(Modellierung betrieblicher Informationssysteme (MobIS 2008), 2008) Kharbili, Marwane el; Medeiros, Ana Karla Alves de; Stein, Sebastian; Aalst, Wil M. P. van der; Loos, Peter; Nüttgens, Markus; Turowski, Klaus; Werth, DirkRegulatory compliance sets new requirements for business process management (BPM). Companies seek to enhance their corporate governance processes and are required to put in place measures for ensuring compliance to regulations. In this sense, this position paper (i) reviews the current work in the context of BPM systems and (ii) suggests future directions to improve the current status. During the literature review, techniques are classified as supporting forward or backward compliance. The latter is a post-execution compliance (i.e. based on execution histories of systems) and the former takes place at designor run-time. In a nutshell, this position paper claims that four main aspects need to be incorporated by current compliance checking techniques: (i) an integrated approach able to cover the full BPM life-cycle, (ii) the support for compliance checks beyond control-flow-related aspects, (iii) intuitive graphical notations for business analysts, and (iv) embedding semantic technologies during the definition, deployment and executions of compliance checks.
- Konferenzbeitrag3D representation of business process models(Modellierung betrieblicher Informationssysteme (MobIS 2008), 2008) Betz, Stefanie; Eichhorn, Daniel; Hickl, Susan; Klink, Stefan; Koschmider, Agnes; Li, Yu; Oberweis, Andreas; Trunko, Ralf; Loos, Peter; Nüttgens, Markus; Turowski, Klaus; Werth, Dirk3D technologies open up new possibilities for modeling business processes. They provide higher plasticity and eliminate some deficits of conventional 2D process modeling such as the limitation of the amount of information to be integrated into a process model in an understandable way. The aim of this paper is to show how the usage of an additional visual modeling dimension may support users in compactly representing and animating business process models. For this purpose, we propose an approach for 3D representation of business process models based on Petri nets. The need for the third modeling dimension is pointed out with three modeling scenarios for which we propose modeling improvements in 3D space. Early evaluations indicate the effectiveness of our approach, which goes beyond conventional modeling tools for business processes.
- KonferenzbeitragEPK-Validierung zur Modellierungszeit in der bflow* Toolbox(Modellierung betrieblicher Informationssysteme (MobIS 2008), 2008) Gruhn, Volker; Laue, Ralf; Kern, Heiko; Kühne, Stefan; Loos, Peter; Nüttgens, Markus; Turowski, Klaus; Werth, DirkDieser Beitrag stellt den Prototyp eines EPK-Modellierungswerkzeugs vor, der Verfahren zur Suche in Graphen nutzt, um Fehler in EPK-Modellen zu identifizieren. Dieses Werkzeug hat gegenüber bekannten Ansätzen zwei Vorzüge: Zum einen ist es nicht notwendig, den (oft sehr großen) Zustandsraum aller möglichen Abläufe in einem Modell zu berechnen. Zum Zweiten kann unser Ansatz auch auf noch nicht vollständig fertiggestellte Modelle angewendet werden. Der Modellierer wird sofort zur Modellierungszeit über mögliche Probleme sowie deren Ursachen informiert und erhält unmittelbare Vorschläge zur Beseitigung der Probleme.
- KonferenzbeitragEin Transformationsmodell zur Überführung von Prozessmodellen in eine Simulationsumgebung(Modellierung betrieblicher Informationssysteme (MobIS 2008), 2008) Petsch, Mathias; Schorcht, Hagen; Nissen, Volker; Himmelreich, Katja; Loos, Peter; Nüttgens, Markus; Turowski, Klaus; Werth, DirkViele Unternehmen nutzen Prozessmodelle, z.B. ereignisgesteuerte Prozessketten, im Rahmen ihrer Anstrengungen, Abläufe transparenter, effektiver und effizienter zu gestalten. Die Simulation von Geschäftsprozessen bietet die Möglichkeit, Auswirkungen von Änderungen im Geschäftsprozess am Simulationsmodell zu überprüfen. Als problematisch erweist sich in der Regel die Überführung von Prozessin Simulationsmodelle. Aufgrund der unterschiedlichen Modellierungsziele und Detaillierungsgrade ist die direkte Übertragung häufig schwierig oder unangemessen. In diesem Beitrag wird basierend am Beispiel Krankenhaus ein Transformationsmodell als Zwischenstufe der Überführung von Prozessin Simulationsmodelle vorgeschlagen und Überlegungen zur weiteren Entwicklung zu einem domänenunabhängigen Transformationsmodell angestellt.
- KonferenzbeitragComponents for growing the RESTful enterprise(Modellierung betrieblicher Informationssysteme (MobIS 2008), 2008) Heil, Andreas; Meinecke, Johannes; Gaedke, Martin; Loos, Peter; Nüttgens, Markus; Turowski, Klaus; Werth, DirkFor a modern enterprise, it is vital to be on the Web. Beyond offering human-readable Web sites, organizations increasingly use the Web as a media for machine-readable data about itself. With the help of technologies like XML feeds, RESTful Web services and semantic markup, new forms of enterprises models emerge in a bottom-up way. These models are easily consumable and facilitate the interaction with departments, partners and customers. Engineering good publishing systems is however extremely challenging. On the one hand, knowledge of many technologies is required; on the other hand, it must be easy to extend systems and data models in accordance to agile businesses. In this paper, we propose a framework of components for publishing dynamically growing enterprise models on the Web, present an implemented system and discuss its use in a case study.
