    Information Systems (IS) interoperability in Public Administration (PA) is a main goal and a major challenge for PA professionals. Achieving interoperability among IS that are technologically disparate and that exist in different organizational contexts is a complex task, being affected by multiple aspects, not yet satisfactorily known and characterized. The aim of this paper is to unveil the forces that influence IS interoperability initiatives in PA. The inquiry was inspired by Lewin’s Field Theory. The data generation process was based on a Delphi study involving 55 experts from PA, IS/IT industry, and academy. A set of 31 forces were identified and ranked based on the level of importance they assume in IS interoperability initiatives. Thirty eight propositions describing restraining and driving influences were also formulated, as well as 24 propositions about forces’ configuration in the current context of Portuguese PA that represent the specific constellation of forces acting in IS interoperability initiatives in that country. The results of this study provide an understanding of the complex of forces acting in IS interoperability, contributing to improve the study, management, and implementation of these initiatives and, consequently, to the establishment of a PA with more adequate, sustained, and sustainable levels of interoperability

    Study Report prepared for the U. S. Air Force, Joint Synthetic Battlespace Analysis of Technical Approaches (ATA) Studies & Prototyping Overview: This paper summarizes research work conducted by organizations concerned with interoperable distributed information technology (IT) applications, in particular the Naval Postgraduate School (NPS) and Old Dominion University (ODU). Although the application focus is distributed modeling & simulation (M&S) the results and findings are in general easily applicable to other distributed concepts as well, in particular the support of operations by M&S applications, such as distributed mission operations. The core idea of this work is to show the necessity of applying open standards for component description, implementation, and integration accompanied by aligned management processes and procedures to enable continuous interoperability for legacy and new M&S components of the live, virtual, and constructive domain within the USAF Joint Synthetic Battlespace (JSB). JSB will be a common integration framework capable of supporting the future emerging simulation needs ranging from training and battlefield rehearsal to research, system development and acquisition in alignment with other operational requirements, such as integration of command and control, support of operations, integration of training ranges comprising real systems, etc. To this end, the study describes multiple complementary Integrated Architecture Framework approaches and shows, how the various parts must be orchestrated in order to support the vision of JSB effectively and efficiently. Topics of direct relevance include Web Services via Extensible Modeling & Simulation Framework (XMSF), the Object Management Group (OMG)’s Model Driven Architecture (MDA), XML-based resource repositories, and Web-based X3D visualization. To this end, the report shows how JSB can − Utilize Web Services throughout all components via XMSF methodologies, − Compose diverse system visualizations using Web-based X3D graphics, − Benefit from distributed modeling methods using MDA, and − Best employ resource repositories for broad and consistent composability. Furthermore, the report recommends the establishment of necessary management organizations responsible for the necessary alignment of management processes and procedures within the JSB as well as with neighbored domains. Continuous interoperability cannot be accomplished by technical standards alone. The application of technical standards targets the implementation level of the system of systems, which results in an interoperable solution valid only for the actual 2 implementation. To insure continuity, the influence of updates, upgrades and introduction of components on the system of systems must be captured in the project management procedures of the participating systems. Finally, the report proposes an exemplifying set of proof-of-capability demonstration prototypes and a five-year technical/institutional transformation plan.

    Achieving Alignment: An Analysis of Enterprise Architecture Best Practices within the United States Air Force

    Get PDF
    This research uncovers areas of best practices that support achieving alignment between an organization’s Information Technology (IT) and its business processes. One principal finding of this effort revealed that the means used to achieve alignment exists within the effective application of Enterprise Architecture (EA), a common practice found throughout the Federal Government, Department of Defense, and the Air Force. EA is the tool used to achieve alignment; likewise, the reason for developing IT architecture is to achieve alignment of IT investments and mission objectives. This research groups the best practices into vision, identification, framework, and governance. Interestingly, these practices relate to an Enterprise Architecture’s depiction of the to be target state, the as is baseline, the tools and models used for communication, and the motivation and management of the transition plan. The insights achieved by this research should strengthen the use of Enterprise Architecture within the Air Force by enabling senior leaders and decision-makers to align strategy and IT investment towards improving mission accomplishment

    Enterprise Architects’ Logics across Organizational Levels: A Case Study in the Norwegian Hospital Sector

    Get PDF
    In this paper, we report about a multilevel case study on the introduction of enterprise architecture (EA) in the Norwegian hospital sector. We utilize institutional logics as a theoretical lens, focusing on the enterprise architects’ logics that are underexplored in information systems research. We have col-lected empirical evidence at national (macro), regional (meso), and local (micro) levels. The findings are classified into nine categories with illustrative statements from the informants, demonstrating their reasoning about the contributions of EA. Furthermore, we identify tensions between enterprise archi-tects and managers and between enterprise architects and medical actors, which indicate the co-existence of multiple competing institutional logics. The most prominent tension is the paradox of EA—demands for local flexibility and autonomy at the micro level versus the predefined rules and standardization that EA imposes across all levels—which makes the institutionalizing process chal-lenging. The enterprise architect logics demonstrate similarities and differences across the various levels, indicating heterogeneity. We conclude this paper with a suggested persona of the enterprise architect, which illustrates the empirical findings

    A readiness assessment framework for Blockchain adoption: a healthcare case study

    Get PDF
    Blockchain technology has been gaining traction across different sectors. It has the potential to immensely benefit the healthcare sector, given the sector's inherent complexities, problems, and inefficiencies. However, to date, no comprehensive, evidence-based effort has been made to understand the readiness of this sector for blockchain adoption. We proposed a readiness assessment framework that encompasses the complex interplay of different underlying factors, social structures, and institutional mechanisms and that covers all key stakeholders. Based on a systematic literature review, the framework is applied to the UAE's healthcare sector and its applicability and usefulness is established. The findings show the multifaceted significance of government readiness in driving blockchain initiatives. Large firms are found to be more willing to leverage the opportunities afforded by blockchain. Lack of clarity on blockchain regulations and laws, and issues pertaining to privacy and trust are found to affect the readiness of all stakeholders. The proposed framework and the study's findings will be useful in guiding policy interventions and developing support mechanisms to strengthen areas related to blockchain adoption
