商品描述

Implement successful and cost-effective enterprise architecture projects. This book provides a new approach to developing enterprise architecture based on the idea of emergent behaviors―where instead of micromanaging system implementation, the enterprise architecture effort establishes clear goals and leaves the details to the implementation teams. System development efforts are measured based on their contribution to achieving business goals instead of implementing specific (possibly outdated) requirements.

 

Most enterprise architecture initiatives employ one of the existing system architecture frameworks such as Zachman or The Open Group Architecture Framework, but these are not well-suited for enterprise architecture in a modern, agile organization. The new approach presented in this book is based on the author’s experience with large enterprise architecture efforts. The approach leverages research into complex adaptive systems and emergent behaviors, where a few simple rules result in complex and efficient enterprise behaviors.

 

Simplifying the task of establishing and maintaining the enterprise architecture cuts the costs of building and maintaining the architecture and frees up those resources for more productive pursuits. System implementers are given the freedom to rapidly adapt to changing user needs without the blessing of the enterprise modeling priesthood, and the architecture is transformed from a static pile of obscure models and documents into an operational framework that can be actively used to manage an enterprise’s resources to better achieve business goals. The enterprise architect is free to stop focusing on building and maintaining models and start focusing on achieving business goals.

 

What You’ll Learn

 

 

  • Refocus enterprise architecture on business needs by eliminating most of the enterprise-level models
  • Delegate tasks to the development teams who do system implementation
  • Document business goals, establish strategies for achieving those goals, and measure progress toward those goals
  • Measure the results and gauge whether the enterprise architecture is achieving its goals
  • Utilize appropriate modeling techniques that can be effectively used in an enterprise architecture

 

 

Who This Book Is For

Architecture practitioners and architecture managers: Practitioners are experienced architects who have used existing frameworks such as Zachman, and have experience with formal architecture modeling and/or model-based system engineering; managers are responsible for managing an enterprise architecture project and either have experience with enterprise architecture projects that were ineffective or are looking for a different approach that will be more cost-effective and allow for more organizational agility. Government program managers looking for a different approach to make enterprise architecture more relevant and easier to implement will also find this book of value.

商品描述(中文翻譯)

實施成功且具有成本效益的企業架構專案。本書提供了一種基於新興行為理念的企業架構開發方法,其中企業架構專案的目標是建立明確的目標,並將細節交給實施團隊,而不是微觀管理系統實施。系統開發的成果是根據其對實現業務目標的貢獻來衡量,而不是實現特定(可能過時)的需求。

大多數企業架構專案都使用現有的系統架構框架,如Zachman或The Open Group Architecture Framework,但這些框架不適用於現代敏捷組織的企業架構。本書介紹的新方法基於作者在大型企業架構專案中的經驗。該方法利用了對複雜適應系統和新興行為的研究,其中少數簡單的規則可以產生複雜且高效的企業行為。

簡化建立和維護企業架構的任務可以降低建立和維護架構的成本,並將這些資源釋放出來用於更有生產力的追求。系統實施者可以在沒有企業建模專家的祝福下快速適應不斷變化的用戶需求,並將架構從一堆靜態的模糊模型和文件轉變為可以主動用於管理企業資源以更好實現業務目標的操作框架。企業架構師可以停止專注於建立和維護模型,並開始專注於實現業務目標。

你將學到什麼:

- 通過消除大部分企業級模型,將企業架構重新聚焦於業務需求
- 將任務委派給進行系統實施的開發團隊
- 記錄業務目標,建立實現這些目標的策略,並衡量實現這些目標的進展
- 測量結果,評估企業架構是否實現其目標
- 使用適當的建模技術,可以在企業架構中有效使用

適合閱讀對象:

- 架構從業人員和架構經理:從業人員是有經驗的架構師,曾使用過Zachman等現有框架,並具有正式架構建模和/或基於模型的系統工程經驗;經理負責管理企業架構專案,可能有過無效的企業架構專案經驗,或者正在尋找更具成本效益且能夠實現更高組織敏捷性的不同方法。政府計劃經理尋找不同的方法來使企業架構更具相關性並更容易實施,也會發現本書有價值。
