Our WBS doesn't look like a family tree!
Variable length of branches not withstanding
- The resulting structure should look like a well-proportioned pyramid
- If it is too flat
- Check to see if any of the items could be gathered under a common head at the next higher level
- If it is too steep
- Check to see if greater decomposition is required
- At some higher level
- Try to limit the number of elements at each level to no more than seven
