using four simple facts (3355) to help us to understand and recap the key concepts of scrum (使用四个简单的事实（3355）来帮助我们理解和概括Scrum的关键概念)

Transparency is vital to the Scrum process, as it allows everyone to see and understand what is really happening in each sprint, achieving a bigger and better communication and trust on the team and in this methodology. This Article shows you how to do it. ( 透明性对于Scrum过程至关重要，因为它允许每个人看到和理解每个Sprint中实际发生的事情，从而在团队和这种方法中实现更大、更好的沟通和信任。这篇文章向您展示了如何做到这一点。)

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。)

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。)

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。)

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？)
