international Workshop on enterprise distributed object computing, EDOCW

作者： Selmin Nurcan Rainer Schmidt Centre de Rech. en Inf. Univ. Paris Paris France HTW-Aalen Aalen Germany

Leading enterprises in the U.S. derive more than 50% of their revenues from services. through services, enterprises stabilize their revenues. this applies not only to pure services such as transportation but also for material products that are augmented by services such as maintenance, consulting and training. Service-oriented enterprise architecture differentiates four layers of services: Business, Software, Platform and Infrastructure. thus, its scope is much broader than the scope of the service-oriented architecture (SOA) and also includes services not accessible through software such as business and infrastructure services. Services of different layers may be interconnected in service (value) nets to provide higher-level services.

international conference on enterprise distributed object computing (EDOC)

作者： Milan Milanovic Dragan Gasevic Luis Rocha FON-School of Business Administration University of Belgrade Serbia School of Computing and Information Systems Athabasca University Canada

In the paper, we investigate principles for modeling flexible business processes enhanced by business rules. In our work, we start from a set of rule patterns, which are identified in the literature as a mean for increasing flexibility of business processes. the previous work on these patterns only considered the implementation level, but not the implications on the modeling level. Moreover, the potential for business process flexibility have not been fully leveraged due to some limitations in externalization of business logic into business rules. In this work, we report on the experience in modeling the set of rule patterns by using a rule-enhanced business process modeling language (rBPMN), and demonstrate the applicability of our findings on a business process case study.

How are enterprise Architecture Design Principles Used?

How are Enterprise Architecture Design Principles Used?

international Workshop on enterprise distributed object computing, EDOCW

作者： Robert Winter Stephan Aier Institute of Information Management University of Saint Gallen Saint Gallen Switzerland

Most agree that enterprise architecture (EA) artifacts include not only representation models, but also design principles [35]. While EA modeling and EA models are covered broadly in the EA state-of-the-art, design activity issues and design principles in particular are still neglected. While there has been some work on EA principles recently, their use has not been systematically surveyed so far. this is surprising because EA principles play an important role in practice. Based on a review of the state-of-the-art of EA principle understanding, we summarize findings from a survey among 70 participants from Swiss and German companies. While EA principles are widely defined, well documented, based on IT strategy and generally perceived as useful, deficiencies are apparent regarding stakeholder involvement, business architecture principles (definition as well as usage), regular principle reviews, and business alignment.

enterprise architecture (EA) management aims at analyzing and improving the enterprise as a whole. A correct and consistent analysis is based on reliable EA data. However, current industrial practice shows that many persons need to collect, prepare, and disseminate EA relevant data while only a small group of persons actually benefits from this information. this state of affairs has a negative impact on the motivation of those who are in charge of gathering EA information. Additionally, the monetary value of this information is often implicit. To overcome this situation, this paper presents an approach to model the supply and demand situation for EA information. the resulting model helps to understand, explain, and ease EA-related information gathering. the applicability of the resulting model is demonstrated with the help of a real world case study from the German federal government.

Governments all over the world have started eGovernment programmes. enterprise architecture (EA) work has emerged as a solution to make a better eGovernment. We investigated the role of EA in the Finnish eGovernment programme called the National Project for IT in Social Services (Tikesos). this study reports what kind of role EA has played in group decisions made by the executive group of Tikesos project. Further, it highlights what has been the main emphasis of the Tikesos project. the research approach is qualitative. We analyzed contents and identified themes from the records of the Tikesos executive group. We found out that EA has not guided the group decisions made by the Tikesos executive group although it has been featured in the plans of the project. Further, we identified three themes: buck-passing, instability in decision making and role of EA.

作者： Matthias Lange Jan Mendling Institute of Information Systems Humbolt University of Berlin Berlin Germany

In recent years, enterprise architecture (EA) management has become an intensively discussed approach in both industry and academia for managing the complexity of an enterprise from a holistic perspective. While there is a strong academic and practical interest in EA frameworks and EA modeling, there is a notable insecurity about the cost benefit ratio of EA. In this paper, we address this research problem with a qualitative research design. We conduct a series of semi-structured interviews with industry experts on enterprise architecture in order to identify classes of EA goals, corresponding EA frameworks adoption to achieve these goals and employed EA benefit assessment approaches. the findings point to, among others, a fairly stable set of EA goals that shift over time and EA frameworks that lack modularity and adjustment capabilities to easily customize towards these goals. this paper is part of an ongoing exploratory research that aims at researching which benefits emanate from EA.

System execution traces are useful artifacts for validating enterprise distributed software system quality-of-service (QoS) properties, such as end-to-end response time, service time, and throughput. With proper planning during development phase of the software lifecycle, it is possible to ensure such traces contain required properties to facilitate analysis for QoS validation. In some case, however, it is not possible to ensure system execution traces contain the necessary properties for QoS analysis. Consequently, this makes it hard to analyze such system execution traces for validation of QoS properties. this paper therefore presents preliminary work on the System Execution Trace Adaptation Framework (SETAF) for adapting system execution traces to support analysis of It also presents preliminary results from applying SETAF to externally developed applications. the initial results show that it is possible to validate QoS properties by adapting system execution traces at analysis time instead of modifying the application's existing source code.

this work investigates the use of knowledge about organizational roles captured in enterprise models for service configuration. Based on an industrial case, it presents a way to extract a role's information demand and to use this as initial configuration for agent-based services. In addition to the meta-model included in the enterprise modeling language, the use of a common ontology is proposed which captures both, the perspective of information demand and services. the architecture of the agent-based services is following the idea to characterize all enterprise members and components by their functions and to represent them by sets of services provided by them. the main contributions of the paper are (1) to show that a role's information demand is relevant for service configurayion, (2) to present a way of extracting information demand from enterprise models, and (3) to extend an approach for SOA-based enterprise representation with information demand.

It is crucial for enterprises to execute business operations in a compliant way. this is especially true for IT-driven business processes as enterprises may face considerable fines when violating laws and regulation in their business processes. through the advent of cloud computing, a new dimension of compliance requirements within the research area of compliant business process design has emerged. Data-sovereignty is one of the major compliance concerns enterprises have to deal with when moving applications and data to the cloud. enterprises are fully responsible for their data, also when the data is not present within their IT premises anymore. this lead to the policy that specific data must not leave the IT premises of the enterprise. In this paper we present an approach to support the human process designer in modelling compliant business processes. We are focusing on compliance requirements which have to be considered in the field of cloud computing. these requirements have been created to meet laws and regulations. these laws and regulations are considering data which is to other countries, for example. Looking at the characteristics of these requirements, we deal with data-centric compliance rules here.
