Yes, seconded. It looks like most of your folder structure is information based. Documents, etc, not necessarily something that needs to be accessible to everyone, or that someone requires a seat of special software to access (Solidworks, for example). And I’m just guessing here…
You could look into something like Microsoft SharePoint for document storage per project, or even something like Trello or Asana for managing that information and assigning tasks to people. I’m currently facing a similar battle on my list of things to tackle in the next year, so I’d be interested to see how you solve this problem.
