Scrum is a framework for product development, which is a container where you can add other practices. XP is one of those practices that you can do within Scrum framework. This article shows you the similarities and differences between them and there are no reasons why a team need choose between Scrum and XP exclusively. (Scrum是一个产品开发框架，它是一个容器，您可以在其中添加其他实践。XP是可以在Scrum框架内完成的实践之一。本文向您展示了它们之间的相似性和差异，并且没有任何理由说明团队需在Scrum和XP之间进行选择。)

The goal of timeboxing is to define and limit the amount of time dedicated to an activity. Scrum uses timeboxing for all of the Scrum events and as a tool for concretely defining open-ended or ambiguous tasks. (时间装箱的目标是定义和限制专用于活动的时间量。scrum 将时间装箱用于所有 scrum 事件, 并用作具体定义无期限或不明确任务的工具。)

The main goal of Scrum rules is to optimize the development process and minimize waste of time. Scrum Master is responsible for ensuring that everyone follows Scrum project-related rules. These rules combine Scrum processes so that everyone knows how to play. (Scrum規則的主要目標是優化開發過程並最大限度地減少浪費的時間。在Scrum Master的是負責確保每個人都遵循的Scrum與項目相關的規則。這些規則將Scrum流程結合在一起，以便每個人都知道如何玩。)

The Scrum team shares different tasks and responsibilities related to product delivery. Every role is closely related. It is recommended that Scrum team members work together in the same place as possible. Let’s look at these roles from the perspective of responsibility, authority and characteristics. (Scrum團隊分享與產品交付相關的不同任務和職責。每個角色都密切相關。建議Scrum團隊成員盡可能在同一位置一起工作。讓我們從責任，權限和特徵的角度來看看這些角色。)

A self-organizing team is a team that has the autonomy to choose how best to do its work, rather than being guided by others outside the team. ( 自組織團隊是一個團隊，擁有自主選擇如何最好地完成工作，而不是由團隊外的其他人指導。)

Scrum in a Nutshell: Scrum relies on which are periods of time when software development is actually done. A Sprint usually lasts from one week to one month to complete an item from the backlog. The goal of each Sprint is to create a potential shippable product. (Scrum依赖于软件开发实际完成的时间段。冲刺通常持续一周到一个月，以完成积压的项目。每个冲刺的目标都是创建一个潜在的可交付产品。)

Role and Responsibilities – The product owner who represents the company’s ownership of the product is a member of the Scrum team. However, the product owner has no authority over other members of the team, as is the case with Scrum Master. The product owner is responsible for the long-term care of the product and the success of the product. (代表公司拥有产品的产品负责人是Scrum团队的一员。但是，产品所有者对团队中的其他成员没有权限，与Scrum Master相同。产品负责人负责长期照顾产品，并负责实现产品成功。)

Without a good product owner, the Scrum project will not succeed. It must be decisive, not only by referring to the required responsibilities, but also by embedding the following thinking patterns: 1) To continuously protect the best interests of customers in terms of functions provided. 2) Protect the organization as a whole in terms of strategic direction and return on investment. (如果没有一个好的产品所有者，Scrum项目就不会成功，他必须具有决定性，不仅要求提到所要求的责任，而且还要嵌入以下思维模式：1) 在提供的功能方面不断保护客户的最佳利益，2) 在战略方向和投资回报率方面保护整个组织。)

Scrum Master is considered to be a project manager in many projects, which is actually a misunderstanding. At the same time, I often see people who argue that Scrum Master is completely different from project managers. So what is Scrum Master’s responsibility? What can we do to become a qualified Scrum Master? ( Scrum Master被认为是许多项目开发中的项目经理，这实际上是一种误解。与此同时，我经常看到那些主张Scrum Master和项目经理完全区别的人。那么Scrum Master的责任是什么？我们可以做些什么来成为一名合格的Scrum Master？)
