敏捷软件开发宣言(Manifesto for Agile Software Development)

我们一直在实践中探寻更好的软件开发方法，身体力行的同时也帮助他人。由此我们建立了如下价值观：We are uncovering better ways of developingsoftware by doing it and helping others do it.Through this work we have come to value:
● 个体互动高于流程和工具(Individuals and interactions over processes and tools)
● 工作的软件高于详尽的文档(Working software over comprehensive documentation)
● 客户合作高于合同谈判(Customer collaboration over contract negotiation)
● 响应变化高于遵循计划(Responding to change over following a plan)
也就是说，尽管右项有其价值，但我们更重视左项的价值（That is, while there is value in the items onthe right, we value the items on the left more）

敏捷宣言遵循的原则(Principles behind the Agile Manifesto)

我们遵循以下原则：We follow these principles:

1. 我们最重要的目标，是通过持续不断地及早交付有价值的软件使客户满意。Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
2. 欣然面对需求变化，即使在开发后期也一样。为了客户的竞争优势，敏捷过程掌控变化。Welcome changing requirements, even late indevelopment. Agile processes harness change for the customer’s competitive advantage.
3. 经常地交付可工作的软件，相隔几星期或一两个月，倾向于采取较短的周期。Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
4. 业务人员和开发人员必须相互合作，项目中的每一天都不例外。Business people and developers must work together daily throughout the project.
5. 激发个体的斗志，以他们为核心搭建项目。提供所需的环境和支援，辅以信任，从而达成目标。Build projects around motivated individuals.Give them the environment and support they need,and trust them to get the job done.
6. 不论团队内外，传递信息效果最好效率也最高的方式是面对面的交谈。The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
7. 可工作的软件是进度的首要度量标准。Working software is the primary measure of progress.
8. 敏捷过程倡导可持续开发。责任人、开发人员和用户要能够共同维持其步调稳定延续。Agile processes promote sustainable development.The sponsors, developers, and users should be ableto maintain a constant pace indefinitely.
9. 坚持不懈地追求技术卓越和良好设计，敏捷能力由此增强。Continuous attention to technical excellence and good design enhances agility.
10. 以简洁为本，它是极力减少不必要工作量的艺术。Simplicity–the art of maximizing the amount of work not done–is essential.
11. 最好的架构、需求和设计出自自组织团队。The best architectures, requirements, and designs emerge from self-organizing teams.
12. 团队定期地反思如何能提高成效，并依此调整自身的举止表现。At regular intervals, the team reflects on how to become more effective, then tunes and adjustsits behavior accordingly.
