Scrum Guide 精读 - 14. Sprint Backlog（完结）

    scrum guide精读，上一次讲了Product Backlog。今天讲讲Sprint Backlog 和 increment， 以及他们的commitment， Sprint goal和Definition of Done。

    Sprint Backlog

    The Sprint Backlog is composed of the Sprint Goal (why), the set of Product Backlog items selected for the Sprint (what), as well as an actionable plan for delivering the Increment (how).

    The Sprint Backlog is a plan by and for the Developers. It is a highly visible, real-time picture of the work that the Developers plan to accomplish during the Sprint in order to achieve the Sprint Goal. Consequently, the Sprint Backlog is updated throughout the Sprint as more is learned. It should have enough detail that they can inspect their progress in the Daily Scrum.

    Sprint Backlog 的内容是这样的：

    Sprint Backlog 由三个部分组成，

    1）Sprint goal，迭代目标，

    2）Product Backlog items PBI 产品待办事项

    3）Actionable plan，可执行的计划

    为了达到迭代目标，Sprint Backlog是由开发团队自己制定并执行的一个计划，这个实施计划有几个特性：

    1）highly visible 高度可见的

    2）real-time，update throughout the sprint在迭代过程中实时更新的

    3）toward Sprint goal。以Sprint goal为导向的。

    基于以上三个特点，每日站会上，大家可以审视这个实施计划，是否顺利地向着迭代目标前进。

    Commitment: Sprint Goal

    The Sprint Goal is the single objective for the Sprint. Although the Sprint Goal is a commitment by the Developers, it provides flexibility in terms of the exact work needed to achieve it. The Sprint Goal also creates coherence and focus, encouraging the Scrum Team to work together rather than on separate initiatives.

    The Sprint Goal is created during the Sprint Planning event and then added to the Sprint Backlog. As the Developers work during the Sprint, they keep the Sprint Goal in mind. If the work turns out to be different than they expected, they collaborate with the Product Owner to negotiate the scope of the Sprint Backlog within the Sprint without affecting the Sprint Goal.

    Commitment 的内容是这样的：

    承诺：Sprint Goal。迭代目标

    迭代目标是迭代的唯一目的。虽然迭代目标是开发团队的承诺，但工作具体如何实施是有充分弹性的。迭代目标也保证了连贯性和专注度，让团队协同工作而不是各自为战。

    之前说过，迭代目标是在迭代计划会议中定义出来，加入到Sprint Backlog里的，开发人员在整个迭代过程中，时刻谨记迭代目标，如果工作内容与预期的不符，开发团队则需要与PO一起协商该如何调整Sprint Backlog的范围，而且不影响迭代目标。

    所以Sprint goal有几个特性：

    1）flexibility 弹性的。Sprint goal不会对约定具体实施内容或功能进行限制。
