Analysing the Contribution of Coupling Metrics for the Development and Management of Process Architectures

Currently, the development and modeling of enterprise architectures is an intensively discussed topic in both science and practice. Process architectures represent a core element in recent enterprise architecture frameworks. With process models being a central means for communicating and documenting the process architectures, both their quality and understandability are decisive. However, the concept of process model quality is still not fully understood. The recent development has highlighted the role of coupling in models. Coupling is expected to represent an important dimension of quality for conceptual models. Still, this perspective is hardly understood and its definition vague. Therefore, this work collects diverse coupling interpretations in the field of process modelling and integrates them to a common and precise definition. Once introduced and formally specified, the metrics serve as a basis for a discussion on coupling and on how the future development in respect to coupling could look like. The main findings are that currently metrics evaluate either the documentation of the process architecture regarding its understandability or they contribute to the individual applications of process architectures. These findings support practitioners selecting metrics for a particular task and scientists to identify research gaps for further development

An Exploration of Enterprise Architecture Research

Management of the enterprise architecture has become increasingly recognized as a crucial part of both business and IT management. Still, a common understanding and methodological consistency seems far from being developed. Acknowledging the significant role of research in moving the development process along, this article employs different bibliometric methods, complemented by an extensive qualitative interpretation of the research field, to provide a unique overview of the enterprise architecture literature. After answering our research questions about the collaboration via co-authorships, the intellectual structure of the research field and its most influential works, and the principal themes of research, we propose an agenda for future research based on the findings from the above analyses and their comparison to empirical insights from the literature. In particular, our study finds a considerable degree of co-authorship clustering and a positive impact of the extent of co-authorship on the diffusion of works on enterprise architecture. In addition, this article identifies three major research streams and shows that research to date has revolved around specific themes, while some of high practical relevance receive minor attention. Hence, the contribution of our study is manifold and offers support for researchers and practitioners alike

Cost Accounting in German hospitals - a comparative assessment of the implementation of cost accounting and analysis of the effect of cost accounting on hospital performance

Mit Blick auf das G-DRG-System gewinnt die Kostenrechnung in Krankenhäusern zunehmend an Bedeutung. Daher erfolgt zunächst die vergleichende Betrachtung des Implementierungsstands der Kostenrechnung in deutschen Krankenhäusern. Anschließend wird ein Strukturgleichungsmodell zur Wirkung der Kostenrechnung auf den Krankenhauserfolg entwickelt und überprüft. Die Befunde haben Implikationen für Forschung und Praxis zur Kostenrechnung in Krankenhäusern.With a view to the G-DRG-system cost accounting in hospitals is becoming increasingly important. Hence a comparative analysis of the implementation of cost accounting in German hospitals is carried out first. Subsequently, a structural equation model for the effect of cost accounting on hospital performance is developed and tested. The findings have implications for research and practice in hospital cost accounting
