The velocity chart shows the amount of value delivered in each sprint, enabling you to predict the amount of work the team can get done in future sprints. It is useful during your sprint planning meetings, to help you decide how much work you can feasibly commit to.

You can estimate your team's velocity based on the total Estimate (for all completed stories) for each recent sprint. This isn't an exact science — looking at several sprints will help you to get a feel for the trend. For each sprint, the velocity chart shows the sum of the Estimates for complete and incomplete stories. Estimates can be based on story points, business value, hours, issue count, or any numeric field of your choice (see Configuring Estimation and Tracking). Please note that the values for each issue are recorded at the time the sprint is started. Changing the Estimate value afterwards will not be reflected in the velocity chart.

 To view the velocity chart,

  1. 上部ナビゲーションバーで Agile リンクの下矢印をクリックし、表示されるドロップダウンメニューから目的のボードを選択します。

  2. Click Report, then select Velocity Chart from the drop-down at left.
  3. Select the relevant sprint from the sprint dropdown ('Toto' in the screenshot  below).

Note that the velocity chart is board-specific, that is, it will only include issues which match your board's Saved Filter.

ベロシティは、スプリントごとにチームが完了する作業量の見積もり合計に対する、複数の最近のスプリントの平均として見積もることができます。したがって、上記の表でベロシティは = (37 + 47 + 50 +57) / 4 = 48 となります。チームのベロシティは、将来のスプリントでチームが完了できるタスクの量を予測するのに便利です。
