eg. do NASA publicly release WBSs for any of their projects? I would like lots of detail, so I can show my team what to aspire to. Most of the WBSs that I've seen online are not very detailed, they seem to want to graphically depict them on one page. I would like a detailed WBS (ideally in spreadsheet form) to show how 100% of the scope can be broken down into small-ish work packages.
Could this link help you?
It's a PPT file, so not in spreadsheet form, but perhaps it could put you and the team on the right path?
