Software Architecture and Decision-Making: Leveraging Leadership, Technology, and Product Management to Build Great Products

Leverage leadership knowledge to make better software architecture decisions. Think deeply but implement slowly.

The overarching goal of software systems (hence, for software architecture) is to build systems that meet quality standards and that provide the highest return on investment (ROI) in the long run or within a defined period of time.

A great product requires a combination of technology, leadership, and product management (including UX). Leadership is primarily about managing uncertainty and making the right judgment. To build great products, technical leaders need to combine technology, leadership, and product management knowledge, and make the right decisions. Many technical mistakes come from the gap between knowledge about these three items and judgment.

In Software Architecture and Decision-Making, Srinath Perera explains principles and concepts that software architects must understand deeply and how to employ those principles to manage uncertainty. The questions and principles discussed in this book help manage uncertainty while building software architecture and provide a framework for making decisions. This book is for all technical leaders in the software industry who make holistic judgments about the systems they build and for future leaders learning the craft.

• Understand the importance of strong decision making with examples from great technical leaders such as the Wright brothers and Kelly Johnson
• Leverage five key questions and seven important principles to understand uncertainties during the design process and make strategic architectural decisions
• Approach the design systematically, first at the macro level and then the individual service level

This definitive guide explains principles and concepts--technical and non-technical alike--that software architects, senior software engineers, and technical leads must understand to manage the inevitable uncertainty involved in building software systems and to drive success of the products for which they are responsible.

運用領導力知識來做出更好的軟體架構決策。深思熟慮，但實施謹慎。

軟體系統（因此也包括軟體架構）的整體目標是建立符合品質標準並在長期或特定時間內提供最高投資回報（ROI）的系統。

一個優秀的產品需要結合技術、領導力和產品管理（包括使用者體驗）。領導力主要是關於管理不確定性並做出正確的判斷。為了建立優秀的產品，技術領導者需要結合技術、領導力和產品管理知識，並做出正確的決策。許多技術上的錯誤來自於對這三個項目的知識和判斷之間的差距。

在《軟體架構與決策》一書中，Srinath Perera解釋了軟體架構師必須深入了解的原則和概念，以及如何應用這些原則來管理不確定性。本書討論的問題和原則有助於在建立軟體架構時管理不確定性並提供決策框架。本書適用於軟體行業中所有對所建立系統做出整體判斷的技術領導者，以及正在學習這門技藝的未來領導者。

- 通過來自萊特兄弟和凱利·約翰遜等偉大技術領導者的例子，了解堅定的決策的重要性。
- 利用五個關鍵問題和七個重要原則，了解設計過程中的不確定性並做出戰略性的架構決策。
- 從宏觀層面和個別服務層面進行系統化設計。

這本權威指南解釋了軟體架構師、高級軟體工程師和技術領導者必須了解的原則和概念，無論是技術還是非技術，以管理在建立軟體系統時不可避免的不確定性，並推動他們負責的產品的成功。

Srinath Perera has been an Apache open source developer for the last 20 years. He has played a major role in the architecture of Apache Axis2, Apache Airavata, WSO2 CEP (Siddhi), and WSO2 Choreo. He has designed two SOAP engines and helped build four. He is a committer (a developer who can commit to a code base) for Apache Axis, Axis2, Apache Geronimo, and Apache Airavata.

He joined WSO2 in 2009 after finishing his PhD. WSO2 products are used by many Fortune 500 companies such as airlines, banks, and governments. At WSO2, he has played an architecture review role for 10+ projects and 100+ releases. He reviewed hundreds of customer solution architectures and deployments and sat in on thousands of architecture reviews. He has published 40+ peer-reviewed research articles, which have been referenced by thousands of other research publications.

Srinath Perera在過去的20年中一直是Apache開源開發者。他在Apache Axis2、Apache Airavata、WSO2 CEP（Siddhi）和WSO2 Choreo的架構中扮演了重要角色。他設計了兩個SOAP引擎並協助建立了四個。他是Apache Axis、Axis2、Apache Geronimo和Apache Airavata的committer（可以提交代碼的開發者）。

他在2009年加入了WSO2，畢業後開始在該公司工作。WSO2的產品被許多財富500強企業使用，例如航空公司、銀行和政府機構。在WSO2，他在10多個項目和100多個版本的架構審查中扮演了角色。他審查了數百個客戶解決方案的架構和部署，並參加了數千次架構審查。他發表了40多篇同行評審的研究文章，這些文章被成千上萬的其他研究出版物引用。
