- KonferenzbeitragAn approach for the management of service-oriented architecture (SoA) based application systems(Enterprise modelling and information systems architectures, 2005) Berbner, Rainer; Grollius, Tobias; Repp, Nicolas; Heckmann, Oliver; Ortner, Erich; Steinmetz, RalfFlexible business processes are a key success factor for enterprises to succeed in globalised markets. The Service-oriented Architecture (SoA) concept is very well suited to support flexible business processes and application systems because capabilities (in form of services) can be composed in the most efficient way to achieve a high level of agility. However, the management of SoA-founded application systems is often neglected. Thus, we present an approach that enhances the traditional SoA concept by additional management functionality, e.g. monitoring mechanisms and SLA management. As a validation of our concept we introduce WSQoSX, a prototypical implementation based on Web Services.
- KonferenzbeitragAn approach to quantify the costs of business process intelligence(Enterprise modelling and information systems architectures, 2005) Mutschler, Bela; Bumiller, Johannes; Reichert, ManfredToday, enterprises are forced to continuously optimize their business as well as service processes. In this context the process-centered alignment of information systems is crucial. The use of business process intelligence (BPI) tools offers promising perspectives in this respect. However, when using BPI tools one has not only to look at potential benefits but at costs as well. Therefore, most enterprises thinking about the purchase of a BPI solution demand for a business case systematically outlining an investment's benefits and costs. This paper summarizes such a business case based on an evaluation of contemporary BPI tools and practical experiences. We present basic BPI concepts, describe BPI benefits and cost drivers and introduce two cost models to gain insights into BPI economics.
- KonferenzbeitragA comprehensive enterprise architecture metamodel and ist implementation using a metamodeling platform(Enterprise modelling and information systems architectures, 2005) Braun, Christian; Winter, RobertDue to the growing importance of alignment, compliance and manageability issues, increased attention is being paid to architectures and architecture management recently. A holistic approach to enterprise architecture requires business related and information systems related artifacts to be equally treated. This paper describes the extension of an existing approach to enterprise architecture and its implementation using a commercial metamodeling platform. In addition to the approach metamodels in general, special attention is paid to the linkages between different architecture layers, both in the underlying model and in its implementation.
- KonferenzbeitragControllability of open workflow nets(Enterprise modelling and information systems architectures, 2005) Schmidt, KarstenAn open workflow net is basically a workflow net extended with a message passing interface. Open workflow nets are adequate models for services or parts of inter-organizational business processes. We investigate the problem of controlla ilit , a natural counterpart of soundness in classical workflow nets (as studied by van der Aalst). We distinguish centralized, distributed, and local controllability and provide solutions to all problems.
- KonferenzbeitragCost oriented modelling of IT-landscapes: generic language concepts of a domain specific language(Enterprise modelling and information systems architectures, 2005) Kirchner, LutzThe accounting of IT-costs is an important aspect not only in the context of corporate cost accounting in general, but also for the management of IT. Various approaches to IT-cost accounting exist. However, they usually are implemented with only loose integration to the company s IT-management. This often causes discrepancies between the numbers used for accounting and those for planning and operating the IT. A tighter integration of the information basis, which the two corporate functions (cost accounting and IT-management) share, is suggested, to solve this problem. One way to achieve this integration, is the implementation of cost accounting concepts in an IT-management method. In this paper we introduce concepts for modelling IT-costs within a domain specific language for the modelling of IT-landscapes. The language is part of an IT-management method, which is currently under development. Using these concepts, costs can be modelled on the same level of abstraction as IT- components, thereby establishing a higher integration level between corporate cost accounting and IT-management.
- KonferenzbeitragA domain engineering approach to specifying and applying reference models(Enterprise modelling and information systems architectures, 2005) Reinhartz-Berger, Iris; Soffer, Pnina; Sturm, ArnonBusiness process modeling and design, as an essential part of business process management, has gained much attention in recent years. An important tool for this purpose is reference models, whose aim is to capture domain knowledge and assist in the design of enterprise specific business processes. However, while much attention has been given to the content of these models, the actual process of reusing this knowledge has not been extensively addressed. In order to address this lack, we propose to utilize a domain engineering approach, called Applicationbased Domain Modeling (ADOM), for the purpose of specifying and applying reference models. We demonstrate the approach by specifying a sell process reference model and instantiating it for a chocolate manufacturer. The benefits of utilizing the ADOM approach for specifying business models are the provisioning of validation templates by the reference models and the ability to apply the approach to various modeling languages and business process views.
- KonferenzbeitragEconomic reflections on managing web services using semantics(Enterprise modelling and information systems architectures, 2005) Wolff, Frank; Oberle, Daniel; Lamparter, Steffen; Staab, SteffenIn Web Services Management different approaches are discussed. In this paper we analyse three options for Web Service Management: a) Web Services standards descriptions and tools (WS*), b) Semantic-supported and c) Automatic semantic Web Services Management. For the analysis of the differences we identify a number of use cases and investigate the information required for the management of Web Services. The three discussed options result in varying processes with considerable differences in the work efforts. As they involve different levels of investment which only repay on a number of similar WS- applications the discrimination between them is not straightforward. A number of factors must be included in the analysis. Based on the cost arguments and the actual status of standards we consider Semantic-supported management of Web Services to be the most promising option for near future.

- KonferenzbeitragA framework for comparing conceptual models(Enterprise modelling and information systems architectures, 2005) Pfeiffer, Daniel; Gehlert, AndreasConceptual models are a widely used mean for documenting software systems as well as describing organisational structures. The trend towards integrated and flexible information systems has encouraged research about the comparison of conceptual models. Current approaches on the identification of similarities between conceptual models often adopt an automation perspective only. In this paper we will unfold severe arguments that a fully automatic model comparison process is not feasible. Furthermore, we will show that only a semiautomatic process can perform the comparison of conceptual models at the semantic level. On this theoretical basis, we will develop a framework which identifies all necessary and sufficient components for comparing conceptual models. We will show that this framework includes all the requirements that a semi-automatic model comparison process must meet.
- KonferenzbeitragFrom reference model to component model(Enterprise modelling and information systems architectures, 2005) Albani, Antonia; Zaha, Johannes MariaStable component models are an essential prerequisite for developing customer-individual business applications. Thereby the information for the identification and specification of their components is gained from domain models. Reference models constitute a potential source for building enterprisespecific domain models. Based on the analysis of existing reference models, this article shows how information available through reference models can be used for the development of stable component models. The derivation of information required for the identification and specification of reusable business components is discussed using example reference modelling techniques. Additionally, potential extensions of existing reference modelling techniques are shown.
