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.

Principles behind the Agile Manifesto

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. he 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.

 

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。

 

敏捷宣言遵循的原则

我们遵循以下原则:
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。

 

 

 

Scrum 是使用最为广泛的一种Agile方法论(Methodology),如果Agile是价值观,那么Scrum就是方法论。

Scrum通常用三三五五归纳:

三个角色: Product Owner, Development Team, Scrum Master

三个产出:Product Backlog, Sprint Backlog, Work Deliverable Software

五个活动:Sprint Planning Meeting, Sprint, Daily Stand up Meeting, Sprint Review, Sprint Retrospective

五个价值观: Courage, Commitment, Focus, Respect, Openness

 

如果把Scrum三个角色比喻成赛龙舟,Product Owner是坐后边舵手,Development Team是桨夫,Scrum Master是前边鼓手。
