敏捷软件开发宣言
敏捷宣言遵循的原则
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。
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。
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。
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。
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。
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。
可工作的软件是进度的首要度量标准。
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。
坚持不懈地追求技术卓越和良好设计，敏捷能力由此增强。
以简洁为本，它是极力减少不必要工作量的艺术。
最好的架构、需求和设计出自自组织团队。
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。
Manifesto for Agile Software Development
Principles behind the Agile Manifesto
Our highest priority is to satisfy the customer
through early and continuous delivery
of valuable software.
Welcome changing requirements, even late in
development. Agile processes harness change for
the customer's competitive advantage.
Deliver working software frequently, from a
couple of weeks to a couple of months, with a
preference to the shorter timescale.
Business people and developers must work
together daily throughout the project.
Build projects around motivated individuals.
Give them the environment and support they need,
and trust them to get the job done.
The most efficient and effective method of
conveying information to and within a development
team is face-to-face conversation.
Working software is the primary measure of progress.
Agile processes promote sustainable development.
The sponsors, developers, and users should be able
to maintain a constant pace indefinitely.
Continuous attention to technical excellence
and good design enhances agility.
Simplicity--the art of maximizing the amount
of work not done--is essential.
The best architectures, requirements, and designs
emerge from self-organizing teams.
At regular intervals, the team reflects on how
to become more effective, then tunes and adjusts
its behavior accordingly.
