敏捷宣言
"
敏捷软件开发宣言
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:
个体和互动 高于 流程和工具
工作的软件 高于 详尽的文档
客户合作 高于 合同谈判
响应变化 高于 遵循计划
也就是说,尽管右项有其价值,
我们更重视左项的价值。

Manifesto for Agile Software Development
We are uncovering better ways of developing
software by doing it and helping others do it.
Through this work we have come to value:
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
That is, while there is value in the items on
the right, we value the items on the left more.
"
12原则
支撑敏捷价值观的12条原则
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来使客户满意。 < 客户为先 >
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,要通过敏捷过程来适应变化。 < 拥抱变化 >
3.经常性地交付可以工作的饮件,比如间隔几个星期或一两个月就交付,交付的时间间隔越短越好。 <短迭代交付 >
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。 < 业务参与 >
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持,辅以信任,从而达成目标。 < 以人为本 >
6.不论团队内外,效果最好且效率最高的传递信息的方式,就是面对面的交流。 < 面对面沟通 >
7.可以工作的软件是首要的进度度量标准。 < 成果导向 >
8.敏捷过程提倡可持续的开发速度。责任人、开发者和用户要能够共同维持其不断稳定延续。 < 保持节奏 >
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。 < 追求卓越 >
10.以简洁为本,它是极力减少不必要工作量的艺术。 < 简单务实 >
11.最好的架构、需求和设计出自自组织团队。 < 团队自组织 >
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行为。 < 持续改进>
We follow these principles:
- 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.
