Over Time

In recent years, enterprise architecture (EA) has captured increasing interest as a means to systematically consolidate and manage various enterprise artefacts in order to provide holistic decision support for business/IT alignment and business/IT landscapes management. To provide a holistic perspective on the enterprise over time, EA frameworks need to co-evolve with the changes in the enterprise and its IT over time. In this paper the authors focus on the emergence of Service-Oriented Architecture (SOA). There is a need to integrate SOA with EA to keep EA relevant and to use EA products to help drive successful SOA. This paper investigates and compares the integration of SOA elements in five widely used EA frameworks: Archimate, The Open Group Architecture Framework (TOGAF), Federal Enterprise Architecture Framework (FEAF), Department of Defence Architecture Framework (DoDAF) and the Ministry of Defence Architecture Framework (MODAF). It identifies what SOA elements are considered and their relative position in the overall structure. The results show that services and related elements are far from being well-integrated constructs in current EA frameworks and that the different EA frameworks integrated SOA elements in substantially different ways. The results can support the academic EA and SOA communities with a closer and more consistent integration of EA and SOA and support practitioners in identifying an EA framework that provides the SOA support that matches their requirements.

<em>Service orientation is an approach in the field of enterprise architecture, business information systems and software application that its main element is the service. Shared services is an organization model of sharing, across an organization. It enables collaboration among the functions/departments. Main motivations for shared services are sharing, promote efficiency, reduce cost, and support scalability. Despite of the widespread use of these two approaches in information technology, there is no tool to optimize the management of them. The aim of this study is Ontological map of service oriented architecture based on zachman framework to adapt it in the reference enterprise architecture framework through implementation ontology views on system architect software and as well as equivalent ontology component with UML diagrams. After the implementation of the suggested model, the results showed that ontology is a formal description and explicit display of objects, concepts and other entities in the relationship between them. In other words, there is a model that describe all that is in fact in to understandable language for the system. Thus the proposed establishes have association between all aspects of zachman framework, also to create a clear description of business concepts in the management of shared services and is effective to provide a unified platform for enterprise modeling.</em>

As the rate of change in both business models and business complexity increases, enterprise architecture can be positioned to supply decision support for executives. The authors propose a dynamic enterprise architecture framework that supports business executive needs for rapid response and contextualized numerical decision support. The classic approaches to business decision making are both over simplified and insufficient to account for the dynamic complexities of reality. Recent failures of historically sound businesses demonstrate that a more robust mathematical approach is required to establish and maintain the alignment between operational decisions and enterprise objectives. We begin with an enterprise architecture (EA) framework that is robust enough to capture the elements of the business within the structure of a meta model that describes how the elements will be stored and tested for completeness and coherence. We add to that the analytical tools needed to innovate and improve the business. Finally, dynamic causal and agent layers are added to account for the qualitative and evolutionary elements that are normally missing or over simplified in most decision systems. This results in a dynamic model of an enterprise that can be simulated and analyzed to answer key business questions and provide decision support. We present a case study and demonstrate how the models are used within the decision framework to support executive decision makers.

Enterprise Architecture Framework

Enterprise Architecture (EA) adalah deskripsi dari misi stakeholder yang menggambarkan rencana pengembangan sebuah sistem atau sekumpulan sistem untuk mencapai sebuah misi organisasi melalui performansi optimal dari proses bisnis dalam sebuah lingkungan TI yang efisien. Untuk bisa menerapkan EA dalam sebuah organisasi, dibutuhkan kerangka kerja yang bersifat fundamental dan satu set alat pendukung yang digunakan untuk mengembangkan suatu EA. Pengukuran performa EA framework dirasa perlu, untuk mengetahui EA framework yang applicable pada kondisi saat ini.  Sehingga dibutuhkan sebuah <em>decision support</em> untuk membantu memilih EA framework berdasarkan kriteria penilaian dari sisi artifact, governance, strategy, consistency, requirement, guidelines, dan continual. Pada makalah ini dibahas pembuatan decission support system untuk mengukur performa EA framework menggunakan Sistem Inferensi Fuzzy Tsukamoto. Parameter yang digunakan untuk batasan fungsi keanggotaan fuzzy berdasarkan data yang diperoleh dari pakar yaitu artifact, governance, strategy, consistency, requirement, guidelines, dan continual. Akurasi sistem dihitung berdasarkan hasil perbandingan dari keluaran sistem dengan hasil penilaian pakar.

Limited Scope

Governments around the world have acknowledged the complexity associated with public sector transformation and have initiated enterprise architecture programs to help manage those complexities and enable the desired strategic transformation. Along with the EA program, governments have adopted some sort of EA framework and/or Service Oriented Architecture (SOA) individually or in integrated form. However, the majority of those EA programs are of limited scope in both EA and SOA practices, and are not comprehensive enough to deal with and manage the associated complexities. As a result, those EA programs suffer from the inability to leverage EA and SOA benefits across agencies or jurisdictional boundaries. Currently, the majority of government agencies use EA and SOA within the agency boundaries to deliver solutions by focusing on technical factors that define detailed blueprints of systems, data, and technology. What is needed rather is effective Whole-of-Government Enterprise Architecture (EA) that facilitates the alignment of individual agencies’ visions with the Whole-of-Government vision to enable sustainable government transformation. Research has pointed out that the Whole-of-Government EA is currently at the conceptual level and still has a long way to go to reach the maturity level required for value realization. This chapter first gives a brief analysis of the current state of enterprise architecture in governments to highlight the current challenges. It then discusses the various scopes of Whole-of-Government EA and recommends the plausible EA approach to enable sustainable connected government based on The Open Group Architecture Framework (TOGAF) and SOA.

Enterprise Architecture Framework

Enterprise architecture has had a resurgence of interest in the IT community in the past ten year; in part because of a mandate for federal agencies of the United States government and in part because of the complexity of managing today’s information systems environments. It has become a critical component of an overall IT governance program to provide structure and documentation to describe the business processes, information flows, technical infrastructure and organizational management of an information technology organization. Many different enterprise architecture frameworks have emerged over the past ten years. Two of the most widely used enterprise architecture frameworks (the Zachman Framework and the Federal enterprise architecture framework) are described and their ability to meet the security and privacy needs of an organization is discussed. These frameworks represent a contrast of industry and government perspectives in addressing issues of key importance to senior IT leadership.
