  1. Effektive / effiziente IT-transformations- Entscheidungsprozesse

    Reiner, Juergen
    Der Beitrag fasst den Forschungsansatz und die Kernergebnisse der Dissertationsarbeit zu folgender Forschungsfrage zusammen: "Welche Möglichkeiten bestehen für Manager, die Effektivität und Effizienz von IT-Transformations- Entscheidungsprozessen zu erhöhen, um qualitativ hochwertige Entscheidungen zu ermöglichen?" Zielsetzung der Arbeit ist die Verbesserung von Entscheidungsprozessen für große IT-Investitionen mit langfristigen Auswirkungen für Unternehmen. Praktische Anforderungen, sowie normativ-rationale und sozio-politische Entscheidungstheorie dienen als Basis für die Konstruktion eines konzeptionellen Frameworks zur Modellierung solcher IT-Transformations-Entscheidungsprozesse. Acht Entscheidungsprozesse in fünf Fallstudien aus verschiedenen Industrien werden analysiert, um Hypothesen zu Zusammenhängen zwischen identifizierten Parametern im Framework zu erforschen. Das Resultat der Analyse zeigt Kernelemente qualitativ hochwertiger IT-Transformations-Entscheidungsprozesse...

  2. A Conceptual Architecture for an Event-based Information Aggregation Engine in Smart Logistics

    Cabanillas Macias, Cristina; Baumgrass, Anne; Di Ciccio, Claudio
    The field of Smart Logistics is attracting interest in several areas of research, including Business Process Management. Awide range of research works are carried out to enhance the capability of monitoring the execution of ongoing logistics processes and predict their likely evolvement. In order to do this, it is crucial to have in place an IT infrastructure that provides the capability of automatically intercepting the digitalised transportation-related events stemming from widespread sources, along with their elaboration, interpretation and dispatching. In this context, we present here the service-oriented software architecture of such an event-based information engine. In particular, we describe the...

  8. Identifying Knowledge Enablers in Organizational Visions: A Synthesis of Theory and Practice

    Kragulj, Florian; Kaiser, Alexander; Grisold, Thomas
    Despite ongoing interest in organizational visions, both in research and practice, there is little understanding of what a vision should entail. What makes a good vision? We approach this question from a knowledge perspective and explore what organizations need to know in order to effectively plan and perform organizational activities. We will review relevant literature and conduct a content analysis of visions of global profit-oriented organizations. By providing a synthesis of theory and practice, we suggest that organizational visions should include three knowledge enablers, which guide the creation as well as the management of (1) knowledge about organizational identity, (2)...

  9. Towards a prioritization of needs to support decision making in organizational change processes

    Kaiser, Alexander; Fahrenbach, Florian; Kragulj, Florian; Grisold, Thomas
    The purpose of this paper is to introduce a decision support system to prioritize needs that are anchored in an organization. We build on a systems-thinking approach and develop a weighted additive index which considers different viewpoints of organizational stakeholders. First, we briefly review the literature about identifying and prioritizing needs from various scientific disciplines. Then, we use boundary critique to identify critical stakeholders that lead to three different viewpoints in the decision support system. The internal view reflects needs that members of the organization find important and urgent to be satisfied. The external view considers knowledge of outsiders, i.e....

  11. Looking Ahead: Part I

    Commendatore, Pasquale; Kubin, Ingrid
    This Chapter summarises the work carried out during the lifetime of the Action by Working Group I whose main task was to build multiregional NEG models. The main results are briefly presented and some of the questions left open are pointed at. Finally, topics for future research are suggested.

  12. Emerging Trade Patterns in a 3-Region Linear NEG Model: Three Examples

    Commendatore, Pasquale; Kubin, Ingrid; Sushko, Iryna
    This chapter draws attention to a specific feature of a NEG model that uses linear (and not iso-elastic) demand functions, namely its ability to account for zero trade. Thus, it represents a suitable framework to study how changes in parameters that are typical for NEG models, such as trade costs and regional market size, not only shape the regional distribution of economic activity, but at the same time determine the emergence of additional trade links between formerly autarkic regions. We survey some related papers and present a three-region framework that potentially nests many possible trade patterns. To focus the analysis,...

  13. Policy Issues in NEG Models: Established Results and Open Questions

    Commendatore, Pasquale; Hammer, Christoph; Kubin, Ingrid; Petraglia, Carmelo
    This paper provides a non-technical overview of NEG models dealing with policy issues. Considered policy measures include alternative categories of public expenditure, international tax competition, unilateral actions of protection/liberalisation, and trade agreements. The implications of public intervention in two-region NEG models are discussed by unfolding the impact of policy measures on agglomeration/dispersion forces. Results are described in contrast with those obtained in standard non-NEG theoretical models. The high degree of abstraction limits the applicability of NEG models to real world policy issues. We discuss in some detail two extensions of NEG models to reduce this applicability gap: the cases of...

  14. Introduction

    Commendatore, Pasquale; Kubin, Ingrid; Bougheas, Spiros; Kirman, Alan; Kopel, Michael; Bischi, Gian Italo
    This collected volume gives a concise account of the most relevant scientific results of the COST Action IS1104 "The EU in the new complex geography of economic systems: models, tools and policy Evaluation", a four-year project supported by COST (European Cooperation in Science and Technology). It is divided into three parts reflecting the different perspectives under which complex spatial economic systems have been studied: (i) the Macro perspective looks at the interactions among international or regional trading partners; (ii) the Meso perspective considers the functioning of (financial, labour) markets as social network structures; and, finally, (iii) the Micro perspective focuses...

  15. Kognitive Belastung als lokales Komplexitätsmaß in Geschäftsprozessmodellen

    Figl, Kathrin; Laue, Ralf
    In unserem Beitrag [FL15] untersuchten wir die Verständlichkeit von Geschäftsprozessmodellen. Wir ließen Probanden Aufgaben zu Prozessmodellen lösen, in denen durch logisches Schlussfolgern Fragen zum Modell zu beantworten waren. Neben aus der Literatur bekannten Einflussfaktoren (z.B. Modellierungserfahrung) untersuchten wir, wie sich Metriken, die auf dem Begriff der kognitiven Belastung (cognitive load) aufbauen, auf die korrekte Beantwortung von Fragen auswirken. Unsere Ergebnisse erlauben eine neue Sicht auf Komplexitätsmetriken für Geschäftsprozessmodelle: Eine bisher kaum beachtete Variable wurde als relevanter Einflussfaktor für die Modellverständlichkeit erkannt - die Interaktivität zwischen Modellelementen. Diese kann durch die Zahl der Modellelemente, die zur Beantwortung einer Frage gemeinsam (in...

  18. Findings from an Experiment on Flow Direction of Business Process Models

    Figl, Kathrin; Strembeck, Mark
    A core aspect of diagrammatic process modeling is the visualization of the logical and temporal order in which tasks are to be performed in a process. While conventions and guidelines exist that promote modeling processes from left-to-right or from top-to-bottom, no empirically validated design rationale can be provided for this choice so far. Therefore, this paper seeks to determine whether some flow directions are better than others from a cognitive point of view. We present the results of a controlled pilot experiment comparing the effects of four flow directions (left-to-right, right-to-left, top-to-bottom, bottom-to-top) on process model comprehension with a small...
