Scrum 使用一种经验主义方法（有时也

This article covers all the key concept of Scrum framework that make you easily be recalled and apply anytime from your mind as systematic knowledge structure (本文涵盖了 scrum 框架的所有关键概念, 使您可以轻松地被召回, 并从您的头脑中随时作为系统的知识结构应用)

Less known than the process of Scrum and probably under-highlighted, but therefore not less important, are the 5 core Scrum Values upon which the framework is based: Commitment – Focus – Openness – Respect – Courage. These values relate to the ethics of Scrum, thereby -from a social point of view- turning Scrum into a value system. (与scrum的过程相比，人们对scrum知之甚少，而且可能低估了这一点，但同样重要的是，该框架所基于的5个核心scrum价值观：承诺——关注——开放——尊重——勇气。这些价值观与Scrum的伦理有关，因此从社会的角度来看，将Scrum转变为一个价值体系。)

Scrum has not been immune to controversy, and its history of invention is a topic of frequent debate. Some professionals believe that Jeff Sutherland, John Scumniotales, and Jeff McKenna invented Scrum in 1993. And then there are others who vouch for Hirotaka Takeuchi and Ikujiro Nonaka as inventing Scrum in 1986. (Scrum并没有不受争议，它的发明历史是一个经常争论的话题。一些专业人士认为Jeff Sutherland、John Scumniotales和Jeff McKenna于1993年发明了Scrum。还有其他一些人也许相信, 在1986年Hirotaka Takeuchi和Ikujiro Nonaka发明了Scrum。)

Scrum is a framework within which people can address complex adaptive problems, while productively and creatively delivering products of the highest possible value. Whilst it is lightweight and simple to understand it is difficult to implement and hard to master. This article tell you why?(Scrum是一个框架，人们可以在其中解决复杂的适应性问题，同时富有成效和创造性地交付具有最高价值的产品。虽然它是轻量级的，易于理解，但很难实现，也很难掌握。这篇文章告诉你为什么？)

Velocity in Scrum is a measure of the amount of work a Team can tackle during a single Sprint and is the key metric in Scrum. Velocity is calculated at the end of the Sprint by totaling the Points for all fully completed User Stories. (速度是一个团队在一次冲刺中可以完成的工作量的度量，也是Scrum中的关键度量标准。在冲刺结束时，通过对所有完全完成的用户故事的点进行合计来计算速度。)

Three friends refer to the main perspective of testing and inspecting increments in business, during and after development. They review each story in informal start-up meetings to provide a shared vision of what will be delivered and help ensure that it is the voice of the team, not a single opinion. (三个朋友指的是在业务、开发期间和开发之后测试检查工作增量的主要视角，例如，业务分析师、开发人员、测试人员在非正式的启动会议中回顾每个故事，以对将要交付的内容给出一个共同的共享愿景，并帮助确保它是团队的声音，而不是单一的意见。)

In empirical process control, you expect the unexpected. With defined process control, every piece of work is understood. In Scrum, an empirical process is implemented where progress is based on observation and experimentation instead of detailed, upfront planning and defined processes. (在经验过程控制中，你期待着意想不到的结果。通过定义的过程控制，可以理解每一件工作。在Scrum中，实现了一个经验过程，其中进度是基于观察和实验，而不是详细的预先规划和定义的过程。)
