Information Systems Transformation: Architecture-Driven Modernization Case Studies (Paperback)

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.

This book 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.

每個主要企業都擁有大量現有軟體系統，這些系統反映了數十年來的補丁和失敗替換所導致的錯綜複雜的IT架構。這些系統大多設計用於支援業務架構，而這些架構已經發生了巨大變化。最好的情況下，這些系統會阻礙敏捷性和競爭力，最壞的情況下，可能會使關鍵業務功能陷入停頓。

架構驅動現代化（ADM）通過捕捉和改造現有應用環境的各個方面，恢復了根深蒂固系統的價值，使舊有基礎設施能夠提供更新的價值並與企業策略和業務架構有效對齊。

本書為組織尋求了解和利用現有系統作為其信息管理策略一部分的方式提供了實用指南。它包括ADM學科、工具和標準的介紹，以及一系列場景，說明ADM如何應用於各種倡議。通過借鑒真實現代化項目的經驗教訓，它提煉出理論，並解釋了每個行業的原則、流程和最佳實踐。

* 作為各種現代化模型在各行業和部門實施的一站式參考和完整指南。
* 每個概念都以各種現代化項目的實際例子加以說明，讓您可以立即應用經過驗證的解決方案並看到結果。
* 由物件管理組織（OMG）架構驅動現代化（ADM）任務組的聯席主席撰寫，該組織為整個IT行業設定了明確的系統現代化標準。
* 網站支持本書，提供最新的ADM規範、教程和白皮書，讓您隨時了解發展中的現代化主題。
