Allocate work assignments in project w/o jazzadmin rights
Teams (project owners) want to be able to edit the work assignment allocation for my testers. Currently, I'm unable to do so, receiving an error message, "The Jazzusers is not authorized to perform the operation. The 'JazzAdmins' role is required to perform this operation."
All managers will need this access in order to balance the work assignments for their direct reports, which allows meaningful metrics regarding availability and workload for each person. Ping me and I can provide the names of the managers that will need this permission.
