Enterprise architecture defines a firm's needs for standardized tasks, job roles, systems, infrastructure, and data in core business processes. Thus, it... helps a company to articulate how it will compete in a digital economy and it guides managers' daily decisions to realize their vision of success. This book clearly explains enterprise architecture's vital role in enabling--or constraining--the execution of business strategy. The book provides clear frameworks, thoughtful case examples, and a proven-effective structured process for designing and implementing effective enterprise architectures.

Driven by the need and desire to reduce costs, organizations are faced with a set of decisions that require analytical scrutiny. Enterprise Architecture... A to Z: Frameworks, Business Process Modeling, SOA, and Infrastructure Technology examines cost-saving trends in architecture planning, administration, and management. To establish a framework for discussion, this book begins by evaluating the role of Enterprise Architecture Planning and Service-Oriented Architecture (SOA) modeling. It provides an extensive review of the most widely deployed architecture framework models. In particular, the book discusses The Open Group Architecture Framework (TOGAF) and the Zachman Architectural Framework (ZAF) in detail, as well as formal architecture standards and all four layers of these models: the business architecture, the information architecture, the solution architecture, and the technology architecture.  The first part of the text focuses on the upper layers of the architecture framework, while the second part focuses on the technology architecture. In this second section, the author presents an assessment of storage technologies and networking and addresses regulatory and security issues. Additional coverage includes high-speed communication mechanisms such as Ethernet, WAN and Internet communication technologies, broadband communications, and chargeback models. Daniel Minoli has written a number of columns and books on the high-tech industry and has many years of technical hands-on and managerial experience at top financial companies and telecom/networking providers. He brings a wealth of knowledge and practical experience to these pages. By reviewing the strategies in this book, CIOs, CTOs, and senior managers are empowered by a set of progressive approaches to designing state-of-the-art IT data centers.

An enterprise architecture tries to describe and control an organisation’s structure, processes, applications, systems and techniques in an integrated... way. The unambiguous specification and description of components and their relationships in such an architecture requires a coherent architecture modelling language. Lankhorst and his co-authors present such an enterprise modelling language that captures the complexity of architectural domains and their relations and allows the construction of integrated enterprise architecture models. They provide architects with concrete instruments that improve their architectural practice. As this is not enough, they additionally present techniques and heuristics for communicating with all relevant stakeholders about these architectures. Since an architecture model is useful not only for providing insight into the current or future situation but can also be used to evaluate the transition from ‘as-is’ to ‘to-be’, the authors also describe analysis methods for assessing both the qualitative impact of changes to an architecture and the quantitative aspects of architectures, such as performance and cost issues. The modelling language presented has been proven in practice in many real-life case studies and has been adopted by The Open Group as an international standard. So this book is an ideal companion for enterprise IT or business architects in industry as well as for computer or management science students studying the field of enterprise architecture.

The purpose of this guide is to provide guidance to organization's in initiating, developing, using, and maintaining their enterprise ... architecture (EA) practice. This guide offers a set of Enterprise Architecture Good Practices that have proven their benefits to organizations and that addresses an end-to-end process to initiate, implement, and sustain an EA program, and describes the necessary roles and associated responsibilities for a successful EA program. Enterprise Architecture is a complete expression of the enterprise; a master plan which “acts as a collaboration force” between aspects of business planning such as goals, visions, strategies and governance principles; aspects of business operations such as business terms, organization structures, processes and data; aspects of automation such as information systems and databases; and the enabling technological infrastructure of the business such as computers, operating systems and networks. While EA frameworks and models provide valuable guidance on the content of enterprise architectures, there is literally no guidance how to successfully manage the process of creating, changing, and using Enterprise Architecture. This guidance is crucially important. Without it, it is highly unlikely that an organization can successfully produce a complete and enforceable EA for optimizing its business value and mission performance of its systems. For example, effective development of a complete EA needs a corporate commitment with senior management sponsorship. Enterprise Architecture development should be managed as a formal program by an Enterprise Architecture Department that is held accountable for success. Since that EA facilitates change based upon the changing business environment of the organization, the enterprise architect is the organization’s primary change agent. Effective implementation requires establishment of business and system compliance with the enterprise architecture, as well as continuous assessment and enforcement of compliance. Waiver of these requirements may occur only after careful, thorough, and documented business case analysis. Without these commitments, responsibilities, and tools, the risk is great that business changes or new systems will not meet organizations business needs, will be incompatible, will perform poorly, and will cost more to develop, integrate, and maintain than is warranted.

About This Book Praise for Enterprise Architecture Planning-- ". the book has given me a wealth of good, fresh ideas about every facet of the... architecture process . makes a substantive contribution to the body of IS planning knowledge." --John A. Zachman Zachman Information Systems Enterprise Architecture Planning is more advanced than traditional system planning approaches because you:* define a stable business model independent of organizational boundaries, systems, and procedures,* define data before application, and* let data determine the sequence for implementing applications systems.Here the authors give you a common-sense approach to Enterprise Architecture Planning. You'll find dozens of examples of architectures, procedures, checklists, and useful guidelines to support these techniques. This is the best guide available to help you ensure a cost-effective, long-term solution.

This is the first book that addresses all three main activities in improving business and technology decisions: the planning, design and assessment of... enterprise architectures (EAs). Emphasis is on medium and large-size organizations in the private sector (such as banks, airlines and auto industries) and the public sector (such as federal agencies, local government organizations and military services in the Department of Defense). The book addresses the challenges faced by EA builders through an organized presentation of the issues and a step-by-step approach. The material is based on real-life EA project experience and lessons learned over a decade working in multiple-contractor, multiple-discipline teams, and multiple-agency environments.

Enterprise governance of information technology is a relatively new concept that is gaining traction in both the academic and practitioner worlds. Going... well beyond the implementation of a superior IT infrastructure, “Enterprise Governance of Information Technology” is about defining and embedding processes and structures throughout the organizations that enable both business and IT people to execute their responsibilities, while maximizing the value created from their IT-enabled investments. At the forefront of the field, the authors draw from years of research and advising corporate clients to present the first comprehensive resource on the topic. Featuring numerous case examples from companies around the world, the book integrates theoretical advances and empirical data with practical application, including in-depth discussion of such frameworks as COBIT and VALIT, which are used to measure and audit the value of IT investments and ensuring regulatory compliance. A variety of elements, including executive summaries and sidebars, extensive references, and questions and activities (with additional materials available on-line) ensure that the book will be an essential resource for professionals, researchers, and students alike.

Enterprise Information Systems: A Pattern Based Approach, 3e, by Dunn/Cherrington/Hollander presents a pattern-based approach to designing enterprise... information systems with a particular emphasis on the enterprise-wide database. This edition is built on the idea that a separation between accounting information systems and management information systems should not exist. We believe patterns help people see the "big picture" of enterprises more clearly and therefore help design better systems. We believe you cannot identify anything that we need to account for that we do not also need to manage; nor can we identify anything we need to manage that we do not also need to account for. In this edition, we will show how a well-designed REA-based Accounting Information System is the Enterprise Information System.
