  1. Towards a Framework for Corporate Data Quality Management

    Boris Otto; Kristin Wende; Alexander Schmidt; Philipp Osl
    Today's market environment requires companies to be able to adapt to new business models and to improve their operational excellence in terms of process efficiency and organisational effectiveness. Agility and flexibility build on high-quality corporate data and powerful corporate data management. This paper proposes a framework for corporate data quality management. The structure of the framework consists of the three layers of Business Engineering (strategy, organisation and information systems) as well as the two perspectives of data management (governance and execution). The scope of the framework is deduced from the state of the art in the domains of IT and...

  3. Definition of Metric Dependencies for Monitoring the Impact of Quality of Services on Quality of Processes

    Christian Mayerl; Kai Huener; Jens-Uwe Gaspar; Christof Momm; Sebastian Abeck
    Service providers have to monitor the quality of offered services and to ensure the compliance of service levels provider and requester agreed on. Thereby, a service provider should notify a service requester about violations of service level agreements (SLAs). Furthermore, the provider should point to impacts on affected processes in which services are invoked. For that purpose, a model is needed to define dependencies between quality of processes and quality of invoked services. In order to measure quality of services and to estimate impacts on the quality of processes, we focus on measurable metrics related to functional elements of processes,...

  4. A Contingency Approach to Data Governance

    Kristin Wende; Boris Otto
    Enterprises need data quality management (DQM) to respond to strategic and operational challenges demanding high-quality corporate data. Hitherto, companies have assigned accountabilities for DQM mostly to IT departments. They have thereby ignored the organizationalissues that are critical to the success of DQM. With data governance, however, companies implement corporate-wide accountabilities for DQM that encompass professionals from business and IT. This paper outlines a data governance model comprised of three components that build a matrix comparable to an RACI chart: data quality roles, decision areas, and responsibilities. The data governance model documents the data quality roles and their type of interaction...

  5. Strategies for a Systematical Patient Identification

    Tobias Mettler; René Fitterer; Peter Rohner
    The growing demand for informational self-determination of patients will not only result in a stronger participation in therapeutic decision making hence causing a change in the physician-patient-relationship, but also require more complex information logistics for health care providers. In this context, a core challenge is the patient identification in a heterogeneous system of diverse ICT solutions. This article presents first approaches how to solve problems arising from insufficient patient identification, both from a single actor's perspective as well as the health network perspective. In a first step, organisation internal as well as cross-organizational mechanisms for patient identification are presented. In...

  6. Measuring Impacts of ICT on the Process Landscape of Public Administrations

    Lars Baacke; René Fitterer; Peter Rohner
    Efficiency, effectiveness and transparency are key objectives of eGovernment. Modern information and communication technologies (ICT) provide means to improve quality of service rendition in public administrations and availability of information across organizational boundaries. The required investments to realize these potential benefits, e.g. for license, implementation, training, operation or maintenance of ICT, can be calculated quite accurately prior to purchase. Significantly more difficult is an assessment of attainable quality improvements, cost savings and utility potentials of newly introduced ICT, which is however a prerequisite for sound investment decisions.The European Commission-funded research project PICTURE addresses this challenge by developing a methodology and...

  7. Towards a Methodology for Service Construction

    Joachim Schelp; Robert Winter
    All large vendors of standard business software have announced to move to service oriented architecture. They claim benefits for their customers with regard to agility and openness. In contrast to the design of software services which has been a focus of research in the computer science community in recent years, the design of enterprise services has not been addressed as much by the information systems research community. This paper outlines a research program on the design of enterprise services. The necessity of different service understandings on different layers of enterprise architecture is shown, conceptual foundations for the design of enterprise...

  8. Reference Modeling and Method Construction - A Design Science Perspective

    Robert Winter; Joachim Schelp
    Due to its importance for the development and the implementation of standard software applications in organizations, reference modeling has gained intensive coverage by IS researchers as well as by practitioners. Method engineering is covered less, in particular by IS practice. There is evidence that the basic construction and application principles for reference models and methods are similar. The goal of this paper is to analyze reuse potentials. As a conceptual basis, the state-of-theart of reference modeling and reference model application as well as the state-of-the-art of method engineering and method application are presented. Reuse potentials are systematically analyzed, and future...

  9. Aggregation of Reference Process Building Blocks to Improve Modeling in Public Administrations

    Lars Baacke; Peter Rohner; Robert Winter
    Efficient methodological support of process modeling is an important prerequisite for the identification of modernization and automation potentials in public administrations. This paper analyzes the specific properties of processes in public administrations and discusses the potential benefits of reuse of process building blocks from a syntactic, semantic and pragmatic perspective.

  10. Enterprise Architecture as a Source for Sustainable Competitive Advantage

    Matthias Stutz
    As the significance of Enterprise Architecture (EA) has rapidly grown over the last decades, its strategic importance for sustainable competitive advantage has not been clearly ascertained. Furthermore the business value returned by EA hasn't been systematically analyzed or quantified. For these reason we critically discus in this paper the basic principles of EA as a strategic resource for generating sustainable competitive advantages for an enterprise and its stakeholder. These fundamentals lead us toward an integrated approach to define strategies for gaining sustainable profit and growth from EA.

  13. CCTS - A Novel Framework for Conceptual Data Modelling

    Alexander Schmidt
    With increasing importance of semantic interoperability in B2B contexts, the need for adequate standards becomes imperative on a process level as well as on the message or data level. Although a multitude of standards have been proposed in recent years none of them became widely accepted as they fell short of offering a satisfying solution. The UN/CEFACT e-business standards stack represents a promising framework for enabling semantic interoperability with the Core Component Technical Specification (CCTS) being an integral constituent for semantic data modelling. However, the scientific foundation of such standards remains rather faint. Therefore, this paper remediates this deficiency by...

  14. Business Interoperability Profiles: Relating Business Interoperability Issues to Technical Interoperability Solutions

    Ulrike Greiner; Christine Legner; Sonia Lippe; Kristin Wende
    The emerging field of interoperability research has come up with a vast number of concepts and technical solutions. However, until today, those technical interoperability solutions are not yet sufficiently linked to the business problems they address. This paper systemizes typical interoperability issues from a business perspective (described by seven Business Interoperability Profiles) and identifies appropriate interoperability solutions which may solve these issues. It extends previous interoperability research by linking the technical view on interoperability to business drivers and needs.

  15. The Challenges of Inter-organizational Business Process Design – a Research Agenda

    Christine Legner; Kristin Wende
    Given the increasing importance of value chain collaboration, business processes need to be more closely aligned across organizational boundaries. Hence, business process modeling and design have to be enhanced and extended to cope with inter-organizational business relationships. Among the challenges that arise are interdependencies between internal and external processes, different process logic and terminology, missing clarification of responsibilities and confidentiality issues. This paper analyzes existing approaches to business process modeling, workflow management and B2B standardization with regard to the specific requirements concerning inter-organizational business process design. It extracts the relevant concepts addressing these requirements and draws up an agenda for...

  16. Service-based Interoperability – Leveraging Web Services for Implementing Industry Standards

    Christine Legner; Tobias Vogel
    With deeper levels of external process integration and a growing number of electro­nic business relationships, enterprises strive for becoming more inter­operable with their business partners. Although B2B standards are supposed to ensure scalable B2B integration and m:n connectivity, enterprises face the challenge of ambiguous interpretations of standards when it comes to their implementation. This paper develops a conceptual model for service-based B2B interoperability which leverages web service technologies for implementing industry standards. The authors instantiate the conceptual mo­del in a concrete B2B scenario in the automotive industry where a consortium of automotive manufacturers and suppliers are current­ly redesigning their inter-organizational...

  17. Design Principles for B2B Services – An Evaluation of Two Alternative Service Designs

    Christine Legner; Tobias Vogel
    A service-oriented architecture (SOA) promises a more flexible intra- and interorganizational integration of heterogeneous application systems. The central design element of a SOA consists of services which encapsulate existing application logic, and can be dynamically combined to form business processes. This paper aims at contributing to the emerging discipline of service engineering by investigating the design principles for B2B services. The authors draw on an analysis of the literature to derive the main design principles for services and evaluate two alternative design proposals for a concrete application scenario in the automotive industry. The results comprise statements on the quality of...

  18. Factors Influencing Networkability in the Health Care Sector - Derivation and Empirical Validation

    Tobias Mettler; Peter Rohner; Robert Winter
    In most sectors of the economy, holistic, local production structures based on manual labour have evolved into activities characterised by a high division of labour between service providers combined with specialisation, the standardisation of service components and extensive networking (industrialisation). In the health care sector, the first signs of a similar development are beginning to crystallise. A key concept for industrialisation is the ability to link up with other players on the basis of commonly agreed standards and services in the sector and low setup costs per case in order to jointly provide high-quality health care treatment oriented towards patient...

  19. Organization of Data Warehousing in Large Service Companies - A Matrix Approach Based on Data Ownership and Competence Centers

  20. A Balanced Scorecard Approach to Measure the Value of Enterprise Architecture

    Joachim Schelp; Matthias Stutz
    The value returned by Enterprise Architecture (EA) is being viewed with increasing consideration by researchers and practitioners. They struggle to justify the EA investments made. Quantifying the Enterprise Architecture benefits has always been a challenge because measurements and real value delivered can not often be expressed in simple technical oriented metrics only.In this paper we suggest a multi-perspective framework, based on the concept of Balanced Scorecard (BSC), for providing guidance about where to identify and quantify the value of EA from the perspective of management. A derived methodology is used to localize a few selected Key Performance Indicators (KPI's) for...
