Manifesto for Agile Software Development
敏捷軟件開發宣言

We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:
我們一直在實踐中探尋更好的軟件開發方法，身體力行的同時也幫助他人。由此我們建立了如下價值觀：

Individuals and interactions over processes and tools
個體和互動 高于 流程和工具

Working software over comprehensive documentation
工作的軟件 高于 詳盡的文檔

Customer collaboration over contract negotiation
客戶合作 高于 合同談判

Responding to change over following a plan
響應變化 高于 遵循計劃

That is, while there is value in the items on the right, we value the items on the left more.

也就是說，盡管右項有其價值，我們更重視左項的價值。

Principles behind the Agile Manifesto
敏捷宣言遵循的原則

We follow these principles:
我們遵循以下原則：

1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
   我們最重要的目標，是通過持續不斷地及早交付有價值的軟件使客戶滿意。
2. Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.
   欣然面對需求變化，即使在開發后期也一樣。為了客戶的競爭優勢，敏捷過程掌控變化。
3. Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
   經常地交付可工作的軟件，相隔幾星期或一兩個月，傾向于采取較短的周期。
4. Business people and developers must work together daily throughout the project.
   業務人員和開發人員必須相互合作，項目中的每一天都不例外。
5. Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
   激發個體的斗志，以他們為核心搭建項目。提供所需的環境和支援，輔以信任，從而達成目標。
6. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
   不論團隊內外，傳遞信息效果最好效率也最高的方式是面對面的交談。
7. Working software is the primary measure of progress.
   可工作的軟件是進度的首要度量標準。
8. Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
   敏捷過程倡導可持續開發。
   責任人、開發人員和用戶要能夠共同維持其步調穩定延續。
9. Continuous attention to technical excellence and good design enhances agility.
   堅持不懈地追求技術卓越和良好設計，敏捷能力由此增強。
10. Simplicity--the art of maximizing the amount of work not done--is essential.
    以簡潔為本，它是極力減少不必要工作量的藝術。
11. The best architectures, requirements, and designs emerge from self-organizing teams.
    最好的架構、需求和設計出自自組織團隊。
12. At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
    團隊定期地反思如何能提高成效，并依此調整自身的舉止表現。
