显示 Visual Studio Online 工作项周期时间

Question

理想情况下，我想通过 Power BI 在 Visual Studio Online 中计算由 Product Backlog Items 表示的整个价值流的周期时间。 （然后我想知道每个状态的时间，即它处于“新”状态多长时间，或者它停留在“已提交”状态多长时间。）

首先，我有兴趣使用表示产品积压项目的created date 和closed date 之间的时间的计算值。在此之后，我热衷于获得找到的值的分布。

product backlog item time between created timestamp to closed timestamp

这将是一个起点，但这当然会显示“按标题排列的持续时间分钟数”。

大多数其他尝试导致：

无法确定字段之间的关系

有没有办法获得一些周期时间的指示？

假设每一行都有一个创建日期和关闭日期，您可以使用 power query duration 函数来获取两个日期之间的差异。

更新：在研究之后（见下面我的 cmets），我意识到构建您需要的查询需要一些奥林匹克级的强大查询技能。所以我为你创建了它:)。以下内容适用于 Power BI 桌面，但由于某种原因无法在 PowerBI.com 中刷新（我正在检查）。为此，您需要将您的 VSO 帐户和查询 ID 放入 ConnectionInfo 记录中。

建议设置备用凭据，而不是使用 BASIC 身份验证。

您可以通过将共享查询保存到您的 VSO 并使用 curl 使用该查询检索 id 来获取 QueryID：

//Replace YOURACCOUNT and YOURPROJECT with correct values below
curl -u username:password https://YOURACCOUNT.visualstudio.com/DefaultCollection/YOURPROJECT/_apis/wit/queries?$depth=1&api-version=1.0

然后您可以使用以下查询（创建一个空白查询并将其粘贴到 Power BI Desktop 的高级编辑器中）。您可能需要调整从“workitems =”开始的一些步骤，因为您的查询可能具有与我的不同的字段。如果您返回创建、解决和关闭的日期，我使用的持续时间计算应该适合您。当在 Power BI Desktop 中受到质询时，您将身份验证设置为“基本”并提供所需的凭据。
