Workspace use case

Use case : 

I am a director of Paris region. I have two subsidiaries : Paris and Versailles.

Subsidiary Paris has two agencies : right bank and left bank.

Subsidiary Versailles has two teams : Construction and Maintenance.

Each team works independently and need to define their internal process in Finalcad environment such as special forms, common observation library and status.

I am therefore structure my organisation like the figure described on the left. 

I will then assort my coworkers into each workspace. Proper parameters has been already set up for these workspaces, and my coworkers can create projects inside.
