Enterprise Architecture Model Untuk Aplikasi Government

Instansi pemerintah di Indonesia telah banyak mengembangkan sistem informasi berbasis Information Technology (IT), tetapi pengembangan tersebut masih belum mengacu pada pemanfaatan framework pengembangan sistem informasi. Oleh karena itu, pada makalah ini bertujuan melakukan eksplorasi Zachman framework untuk diterapkan pada pengembangan sistem informasi aplikasi Government, dengan studi kasus pada instansi pemerintah Dinas Tenaga Kerja, Transmigrasi dan Kependudukan (Dinakertransduk) Provinsi Jawa Tengah. Hasil dari Zachman framework adalah dalam bentuk arsitektur level untuk perencana dengan memperhatikan seluruh aspek pada organisasi instansi pemerintah. Arsitektur level yang dihasilkan dapat memberikan manfaat untuk ketersediaan dokumentasi data, sistem dan teknologi yang mendukung proses bisnis instansi pemerintah dengan pengembangan IT

A Pattern-based Approach to Quantitative Enterprise Architecture Analysis

Enterprise Architecture (EA) management involves tasks that substantially contribute to the operations of an enterprise, and to its sustainable market presence. One important aspect of this is the availability of services to customers. However, the increasing interconnectedness of systems with other systems and with business processes makes it difficult to get a clear view on change impacts and dependency structures. While management level decision makers need this information to make sound decisions, EA models often do not include quality attributes (such as availability), and very rarely provide quantitative means to assess them. We address these shortcomings by augmenting an information model for EA modeling with concepts from Probabilistic Relational Models, thus enabling quantitative analysis. A sample business case is evaluated as an example of the technique, showing how decision makers can benefit from information on availability impacts on enterprise business services

INTEGRATING MOBILE IT/CLOUD INTO ENTERPRISE ARCHITECTURE: A COMPARATIVE ANALYSIS

Since the year 2000, Enterprise Architecture has been the object of focus as a method for promoting an IT architecture that establishes consistency between corporate business and IT strategies, and it has been applied mostly in global corporations. On the other hand, with the recent progress in Mobile IT technology and Cloud computing, in the IT systems of global corporations, the shift from conventional on premise server-based IT systems to Cloud computing, such as Software as a Service (SaaS), Hybrid Cloud, and connected Mobile IT systems, has become more pronounced. In promoting Enterprise Architecture, EA based upon an approach compatible to the cutting-edge IT technologies of Mobile IT/Cloud computing will be required by global corporations. This paper elucidates key points for EA methods to respond to the cutting-edge IT technology that will be required in the future by conducting a comparative analysis of the support environments of Mobile IT elements and related Cloud computing technology in each EA framework currently used widely in many global corporations

Tartarus – una estrategia para construir y expresar arquitecturas empresariales

Las compañías emplean importantes esfuerzos en establecer diagnósticos empresariales y planes estratégicos de inversión, para lograr y/o mantener lugares competitivos en el mercado. El profundo análisis organizacional requerido para tal fin, debe ser idealmente apoyado en metodologías para el levantamiento, depuración y comunicación de la información. Los exhaustivos resultados que emergen de un estudio a nivel empresarial, son susceptibles a la ambigüedad, inconsistencia y mala interpretación, dificultando la importante tarea de transmitir hechos relevantes para el mejoramiento de la empresa. En este artículo, presentamos un conjunto de estrategias para la construcción de modelos empresariales, que permiten describir la realidad organizacional y obtener artefactos consistentes para comunicarla. Dichos modelos son definidos a través de un metamodelo, que abarca los principales conceptos empresariales, abstraídos de algunos de los marcos arquitecturales que gozan de mayor reconocimiento en el mercado. Adicionalmente, ofrecemos un ejemplo, para ilustrar el modelado de un fragmento de la arquitectura empresarial de una organización financiera, con la motivación de derivar artefactos que propicien su divulgación

Big data architecture for pervasive healthcare: a literature review

Pervasive healthcare aims to deliver deinstitutionalised healthcare services to patients anytime and anywhere. Pervasive healthcare involves remote data collection through mobile devices and sensor network which the data is usually in large volume, varied formats and high frequency. The nature of big data such as volume, variety, velocity and veracity, together with its analytical capabilities com-plements the delivery of pervasive healthcare. However, there is limited research in intertwining these two domains. Most research focus mainly on the technical context of big data application in the healthcare sector. Little attention has been paid to a strategic role of big data which impacts the quality of healthcare services provision at the organisational level. Therefore, this paper delivers a conceptual view of big data architecture for pervasive healthcare via an intensive literature review to address the aforementioned research problems. This paper provides three major contributions: 1) identifies the research themes of big data and pervasive healthcare, 2) establishes the relationship between research themes, which later composes the big data architecture for pervasive healthcare, and 3) sheds a light on future research, such as semiosis and sense-making, and enables practitioners to implement big data in the pervasive healthcare through the proposed architecture

An Exploration of Enterprise Architecture Research

Management of the enterprise architecture has become increasingly recognized as a crucial part of both business and IT management. Still, a common understanding and methodological consistency seems far from being developed. Acknowledging the significant role of research in moving the development process along, this article employs different bibliometric methods, complemented by an extensive qualitative interpretation of the research field, to provide a unique overview of the enterprise architecture literature. After answering our research questions about the collaboration via co-authorships, the intellectual structure of the research field and its most influential works, and the principal themes of research, we propose an agenda for future research based on the findings from the above analyses and their comparison to empirical insights from the literature. In particular, our study finds a considerable degree of co-authorship clustering and a positive impact of the extent of co-authorship on the diffusion of works on enterprise architecture. In addition, this article identifies three major research streams and shows that research to date has revolved around specific themes, while some of high practical relevance receive minor attention. Hence, the contribution of our study is manifold and offers support for researchers and practitioners alike
