Modelo de evaluación de sistemas interorganizacionales de información

The purpose of this research is to propose an evaluation model for Inter-Organization Information Systems (IOS) within the so-called Information Systems Success theory. Within the framework of Multimethodology, a series of techniques are developed to make this proposal. Based on a systematic review of the literature, a set of 28 documents that present models of evaluation of Intra and Interorganizational Information Systems is obtained. In order to establish a preliminary version of the IOS success evaluation model, these models are analyzed and coded in the light of the content analysis. Through this method, the dimensions, characteristics and relationships of the model are proposed. Subsequently, this initial proposal is evaluated through the criteria of experts based on the Delphi method, concluding with some adjustments and reaching the final version of the model consisting of 8 dimensions, their relationships, and 48 characteristics.La presente investigación tiene como objetivo proponer un modelo de evaluación de Sistemas Inteorganizacionales de Información (IOS) dentro de la denominada teoría del Éxito de Sistemas de Información.

Design management of electronic data interchange systems

This study deals with the management of the design process of Electronic Data Interchange (EDI) systems. Its objectives are (1) to investigate the design process of EDI systems from a practical and theoretical perspective; (2) to develop a model to describe factors relevant to EDI system-design success; (3) to investigate the proposed model empirically. The model to be developed is called the Design Management Theory for EDI systems. Characteristics of EDI systems and two relevant schools within organization theory e.g. the Decision-making school and the Enviromnental school provide a foundation for the Design Management Theory for EDI systems. Propositions are formulated around the constructs EDI system-design success, design management design environment, contracting success, contracting management, and contracting environment. Variables and hypotheses are defined. The Design Management Theory is investigated empirically by quantitative and qualitative measures. The quantitative approach uses the survey data of 35 Dutch EDI projects. Survey data were analysed by multi- variate analysis methods. The qualitative approach uses a case study of one EDI project, the EDI Flower project, and analytic induction of the case study data. The results indicate that the Design Management Theory partly explains the success of EDI system design. Higher levels of contracting management, contracting success, and design management cause a more successful EDI system design. Relevant factors with regard to contracting management and design management were distinguished. The results indicate the strengths of the Decision-making school in particular the disjointed incrementalistic view of the rational perspective. The results indicate the strengths of the Environmental school, in particular the resource dependency view of the contingency perspective and the strategic choice perspective. Improvements were suggested for the theory related to specification of EDI system-design success, design environment and contracting environment

Industrialising Software Development in Systems Integration

Compared to other disciplines, software engineering as of today is still dependent on craftsmanship of highly-skilled workers. However, with constantly increasing complexity and efforts, existing software engineering approaches appear more and more inefficient. A paradigm shift towards industrial production methods seems inevitable. Recent advances in academia and practice have lead to the availability of industrial key principles in software development as well. Specialization is represented in software product lines, standardization and systematic reuse are available with component-based development, and automation has become accessible through model-driven engineering. While each of the above is well researched in theory, only few cases of successful implementation in the industry are known. This becomes even more evident in specialized areas of software engineering such as systems integration. Today’s IT systems need to quickly adapt to new business requirements due to mergers and acquisitions and cooperations between enterprises. This certainly leads to integration efforts, i.e. joining different subsystems into a cohesive whole in order to provide new functionality. In such an environment. the application of industrial methods for software development seems even more important. Unfortunately, software development in this field is a highly complex and heterogeneous undertaking, as IT environments differ from customer to customer. In such settings, existing industrialization concepts would never break even due to one-time projects and thus insufficient economies of scale and scope. This present thesis, therefore, describes a novel approach for a more efficient implementation of prior key principles while considering the characteristics of software development for systems integration. After identifying the characteristics of the field and their affects on currently-known industrialization concepts, an organizational model for industrialized systems integration has thus been developed. It takes software product lines and adapts them in a way feasible for a systems integrator active in several business domains. The result is a three-tiered model consolidating recurring activities and reducing the efforts for individual product lines. For the implementation of component-based development, the present thesis assesses current component approaches and applies an integration metamodel to the most suitable one. This ensures a common understanding of systems integration across different product lines and thus alleviates component reuse, even across product line boundaries. The approach is furthermore aligned with the organizational model to depict in which way component-based development may be applied in industrialized systems integration. Automating software development in systems integration with model-driven engineering was found to be insufficient in its current state. The reason herefore lies in insufficient tool chains and a lack of modelling standards. As an alternative, an XML-based configuration of products within a software product line has been developed. It models a product line and its products with the help of a domain-specific language and utilizes stylesheet transformations to generate compliable artefacts. The approach has been tested for its feasibility within an exemplarily implementation following a real-world scenario. As not all aspects of industrialized systems integration could be simulated in a laboratory environment, the concept was furthermore validated during several expert interviews with industry representatives. Here, it was also possible to assess cultural and economic aspects. The thesis concludes with a detailed summary of the contributions to the field and suggests further areas of research in the context of industrialized systems integration
