- KonferenzbeitragTowards an integrated modelling framework for engineering design processes(Enterprise modelling and information systems architectures, 2005) Miatidis, Michalis; Jarke, MatthiasEngineering design processes consist of an administration level where the coordination of the design workflow takes place and a process level where human actors perform their tasks following engineering methodologies. Most of the existing information system infrastructures support either of these two levels, resulting in isolated islands of support. In this paper, we present an integrated modelling framework that bridges the gap between these two levels. The key idea behind this framework is a multi-perspective modelling language that adequately captures both levels by interrelating them according to a number of semantic bridges. Our approach has been evaluated in an interdisciplinary chemical engineering project focusing on the conceptual design and basic engineering phases of the nylon production.
- 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.
- 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.
- KonferenzbeitragTowards the interchange of configurable EPCs: An XML-based approach for refernce model configuration(Enterprise modelling and information systems architectures, 2005) Mendling, Jan; Recker, Jan; Rosemann, Michael; Aalst, Wil van derRecent research has led to proposals for the model-driven configuration of Enterprise Systems (ES) by the help of configurable reference models. While the proposed on gura le P s (C-EPCs) provide adequate conceptual support towards reference model configuration, the issue of translating the configured models towards executable process specifications has not been approached yet. A first step in this direction is the definition of a machine-readable format for C-EPCs that can be used as an interchange format and as an input format for transformations. This paper proposes a C-EPC representation in XML based on the P Mar up anguage (EPML) format. We take the formal C-EPC syntax definition as a starting point to define the requirements for a respective extension to EPML and introduce a C-EPC representation in EPML. Furthermore, we introduce the - P alidator, a program that generates validity reports for C-EPCs represented in EPML. The C-EPC Validator can be used to validate both configurable and configured C-EPCs. Finally, we highlight future application areas of the C-EPC schema.
- 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.
- KonferenzbeitragIT architecture management: A framework for IT-services(Enterprise modelling and information systems architectures, 2005) Moser, Christoph; Bayer, FranzIn practice more and more concepts are used for IT service management. Standards like the IT Infrastructure Library (ITIL) ensure that IT services are delivered to meet all requirements of the business processes. They permit the effective and efficient design, operation and maintenance of IT services and the underlying service components in the short run. However, cost savings through the planning and controlling of the IT architecture remain unattended. This shortcoming can be eliminated with the integration of IT architecture management and IT service management frameworks into a superior IT governance framework. Since ITIL is one of the most established standards for IT service management it is used as the starting point to align IT service and architecture management.
- 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.
- 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 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.
- KonferenzbeitragUnbundling and deploying CRM applications as e-services(Enterprise modelling and information systems architectures, 2005) Falcone Sampaio, Pedro R.; Yong, HeThe development of Customer Relationship Management (CRM) capabilities by incrementally sourcing and combining "best of breed" services from different providers is a key lever for reducing implementation risks and costs linked to CRM projects. Central to a "best of breed" and incremental CRM implementation strategy is the unbundling of CRM functionality into a portfolio of services that can be sourced from application service providers and/or developed internally within the client organization. This paper addresses issues and methodological steps relating to unbundling CRM applications into self contained e-Services and developing the service blueprint to deliver the e-Service. In particular a study is conducted illustrating the unbundling of customer segmentation functionality towards modeling, packaging and delivering the business process functionality as an on-demand e-Service.
