Every major enterprise has a significant installed base of existing software systems that reflect the tangled IT architectures that result from decades of patches and failed replacements. Most of these systems were designed to support business architectures that have changed dramatically. At best, these systems hinder agility and competitiveness and, at worst, can bring critical business functions to a halt. Architecture-Driven Modernization (ADM) restores the value of entrenched systems by capturing and retooling various aspects of existing application environments, allowing old infrastructures to deliver renewed value and align effectively with enterprise strategies and business architectures. Information Systems Transformation provides a practical guide to organizations seeking ways to understand and leverage existing systems as part of their information management strategies. It includes an introduction to ADM disciplines, tools, and standards as well as a series of scenarios outlining how ADM is applied to various initiatives. Drawing upon lessons learned from real modernization projects, it distills the theory and explains principles, processes, and best practices for every industry. Acts as a one-stop shopping reference and complete guide for implementing various modernization models in myriad industries and departments Every concept is illustrated with real-life examples from various modernization projects, allowing you to immediately apply tested solutions and see results Authored by the Co-chair of the Object Management Group (OMG) Architecture-Driven Modernization (ADM) Task Force, which sets definitive systems modernization standards for the entire IT industry A web site supports the book with up to date coverage of evolving ADM Specifications, Tutorials, and Whitepapers, allowing you to remain up to date on modernization topics as they develop

In this interdisciplinary narrative, the never-ending "completion" of China's most important street offers a broad view of the relationship between art and ideology in modern China. Chang'an Avenue, named after China's ancient capital (whose name means "Eternal Peace"), is supremely symbolic. Running east-west through the centuries-old heart of Beijing, it intersects the powerful north-south axis that links the traditional centers of political and spiritual legitimacy (the imperial Forbidden City and the Temple of Heaven). Among its best-known features are Tiananmen Square and the Great Hall of the People, as well as numerous other monuments and prominent political, cultural, financial, and travel-related institutions. Drawing on Chang'an Avenue's historic ties and modern transformations, this study explores the deep structure of the Chinese modernization project, providing both a big picture of Beijing's urban texture alteration and details in the design process of individual buildings. Political winds shift, architectural styles change, and technological innovations influence waves of demolition and reconstruction in this analysis of Chang'an Avenue's metamorphosis. During collective design processes, architects, urban planners, and politicians argue about form, function, and theory, and about Chinese vs. Western and traditional vs. modern style. Every decision is fraught with political significance, from the 1950s debate over whether Tiananmen Square should be open or partially closed; to the 1970s discussion of the proper location, scale, and design of the Mao Memorial/Mausoleum; to the more recent controversy over whether the egg-shaped National Theater, designed by the French architect Paul Andreu, is an affront to Chinese national pride.

This edited collection explores the visibility of modernization in architecture produced in different capitalist regions across the world and provides readers with a historico-theoretical and historico-geographical discussion. Focusing on a particular building type, an influential architect’s work, as well as relevant texts and documents, each chapter addresses the many facets of "delay" which are central to the problematization of capitalism’s progressive dissemination of technological and aesthetic regimes of modernism. This collection underlines the centrality of temporality for a critical understanding of colonialism, modernism, and capitalism. The book is primarily concerned with the historical timeline, the tangential point when a nation enters modernization processes. In exploring modernism in diverse regions such as East Asia, Pacific, Eastern Europe, and Iran, each chapter addresses the historiographic and architectonic unfolding of modernization beyond the western hemisphere. The exploration of these diverse case-studies will be of interest to students of architecture and researchers working on the collision of temporalities and the subject's critical importance for different country’s built-environments.

'Modernization' has become the soundbite of the 1990s. What is the role of architecture within this quest for the modern? The modernism of the 1990s is very different from its precursors earlier this century. Where the pre-war Modern Movement saw itself as an instrument of social change, today's modernism is most visible in shops and restaurants; where the International Style tended towards standardization and uniformity, architects today aim for flexibility and individuality. In examining these and other contemporary issues, Modernism and Modernization in Architecture looks towards a new definition of modernism for our times.
