Under, how are linked all the tree structures of the 3D WBS model.
I did not integrate the Resources (RBS), because I think that they must not be assigned to tasks, I prefer to use the weighting method of tasks, with hours, on huge schedules.
One Zone contains several Products. One Product contains several Activities.
There is one responsible from OBS by task.
There is one responsible from OBS by Workpackage.
ZBS is divided by functional Zones (process units, releases, etc.) and by physical Zones (Geographical, target machine type, etc.).
PBS is divided by Systems (SBS) and components (pure Products).
The workpackage are at the crossing between one Zone, one Product, and one OBS responsible.
