An Architecture for Collaborative Scenarios Applying a Common BPMN-Repository

Collaborative business scenarios require a flexible integration of enterprises. To manage inter-organizational business processes, existing concepts for business process management (BPM) need to be adopted and extended. This paper presents a conceptual architecture for cross-enterprise processes’ planning, implementation, and controlling. Core component of the architecture is a distributed repository managing all required data and information, which especially obtains a process-oriented view on collaboration networks. Cross-organizational processes need close coordination among networking partners. This is achieved through the integration of business process models. Thus we further propose …

Multiperspective Evaluation of Reference Models – Towards a Framework

Within the information systems field, reference models have been known for many years. Despite the relevance of reference model quality, little research has been done on their systematic evaluation. Based on an analysis of prior work on reference model quality, we propose a framework for the multiperspective evaluation of reference models. The framework comprises 15 perspectives. Each perspective is discussed with respect to its strengths and limitations. As well, we provide examples of the types of research that have already been undertaken on each perspective.

Modellierung überbetrieblicher behandlungsprozesse durch objekt-petrinetze

Clinical processes are often performed by the cooperation of different healthcare organization. But even that for modeling of such processes the object Petri nets can be used, they often lack of intuitive comprehensibility. This contribution presents an interpretation of object Petri nets which assigns abstract net elements to real objects of the healthcare domain. By doing this it helps domain user to apply this Petri net type to the modeling of clinical processes. The application of this approach is demonstrated.

Model Driven Architecture (MDA)

Visualisierung von Geschäftsmodellen

Moglichkeiten, ein Unternehmen modellhaft abzubilden, werden entwickelt, wenn neue Fragestellungen auftreten und beantwortet werden mussen. So werden z.B. Buchungssatz und Konto genutzt, um Geschaftsvorfalle im Rechnungswesen zu dokumentieren. Eine Bilanz wird aufgestellt, um die Mittelherkunft und Mittelverwendung eines Unternehmens zu einem bestimmten Stichtag festzustellen. Stellenbeschreibungen tragen im Rahmen der Aufbauorganisation zu einer Klarung der Aufgabenverteilung bei.

Business Process Reference Models: Survey and Classification

Within the Information Systems field, reference models are well-known for many years. The aim of this paper is to survey and to describe reference models for business processes. Our analysis of 30 process reference models is based on a framework consisting of criteria such as application domain, used process modeling languages, model's size, known evaluations and applications of process reference models. Furthermore, we identify model domains, which have been dealt with, describe similarities and differences between the available process reference models, and point to open research questions.

Business models to offer customized output in electronic commerce

Seller-driven business models (e.g. online bookstores) have been successfully implemented and concretized in Electronic Commerce both in practice and science in the last years. In contrast to this we can depict that more customer-driven business models are implemented in the beginning. One major problem of customizable products and services in Electronic Commerce can be found in the adaptation of the human advisory activity which is inevitable in the traditional sale. For this reason we depict the customization in the customer's view and the corresponding business models in electronic markets. Main focus will be on the improvement of the communication interface between customer and seller i…

Zur Identifikation von Strukturanalogien in Datenmodellen

On the one hand, data models decrease the complexity of information system development. On the other hand, data models causes additional complexity. Recently structural analogies are discussed as instruments reducing the complexity of data models. This piece of research presents a procedure to identify structural analogies in data models and demonstrates its performance by analyzing Scheer’s reference model for industrial enterprises (Y-CIM-model). The proposed procedure is based on formalizing data models within set theory and uses a quantitative similarity measure. The obtained results show both identical and very similar information structures within the Y-CIM-model. Furthermore, ways of…

Die multiperspektivische Verwendung von ERP-Systemen in der Wirtschaftsinformatik-Lehre

Dieser Beitrag zeigt, wie ERP-Systeme in der Lehre dazu beitragen konnen, das Wissen uber Geschaftsprozesse, Wirtschaftsinformatik und praktische Erfahrungen zu vernetzen. Dazu wird ein ERP-System als Lerntrager eingesetzt, das zugleich in verschiedene konzeptionelle Ebenen (Metadaten, Daten, Programmcode, Anwendungen, Prozesswissen) aufgeteilt wird. Diese Ebenen werden zu geeigneten Benutzergruppen zusammengefuhrt, die jeweils unterschiedliche Perspektiven auf ein ERP-System — wie bspw. die Anwender- oder Entwicklerperspektive — darstellen. Auf dieser Basis werden einzelne Themenbereiche der Wirtschaftsinformatik-Vorlesungen aufgegriffen und anhand eines ERP-Systems verdeutlicht. Dabei neh…

Classification of reference models: a methodology and its application

Classification is an important tool for perception and can be found in numerous scientific disciplines. Several application areas of classification are described in the context of information modeling. The usefulness of classification for reuse resp. selection of reference models is emphasized. A methodology to systematically create classification systems will be introduced. Furthermore, a classification system for reference models will be developed with the aid of the proposed methodology. This classification system gives a comprehensive, but abstract survey of 26 reference models found in the literature.

Comparing the Control-Flow of EPC and Petri Net from the End-User Perspective

This contribution describes the results of a laboratory experiment which compares the Event-driven Process Chain (EPC) and Petri net (C/E net) regarding their approaches to represent the control-flow of processes. The outcome of the experiment indicates that from end-user perspective the EPC approach of applying connectors is superior to the token game. However, the non-local semantic of the EPC OR-connector clearly had a negative impact on end-user comprehension. The experiment also illustrates that the perceived ease-of-use and the intention to use the EPC notation is higher than C/E net.

Specification of Business Components

Component-based software development is a potential reuse paradigm for the future. While the required technologies for a component-style system development are widely available, for instance Sun's Enterprise Java Beans, a problem inhibits the breakthrough of the component paradigm in business applacation domains: compared to traditional engineering disciplines there is a lack of standardized methods to describe business components. Such a description has to address several aspects: What services are offered and requested by a business component? How can these services be used? Are there any interdependencies between the services of a set of business components? What quality characteristics …
