2. Add the following permissions:
   
   • Global:
     
     • Project Management - Tiles Navigate
     • Projects - Navigate
     • Resource Management - Navigate
     • Staffing - Navigate
     • Staffing Plan - Navigate
   • OBS:
     
     • Project - View
     • Resource - Edit
     • Resource - Soft Book
     • Resource - View
     • Resource - View Book
3. Connect to Modern UX with this user
4. Go to Staffing page /pm/#/staffing with a view returning 
   
   1. many projects
   2. little projects and per period metrics
   3. little projects, per period metrics and grouping by Resource
