Manage Dispatch
ServiceVisit lets you manage dispatch, which means deciding which technicians work a Work Order. You would use it when a Work Order needs more than one person. It also puts the Dispatch tab in the Schedule area.
On a Work Order, the Assigned Crew section lists the technicians on it. This permission lets you use Swap beside the primary technician to choose a different crew member as primary. Adding another technician with Assign, and choosing whether they are Secondary, Helper or Apprentice, also works for someone who can assign jobs.
Moving a Work Order to a new time or technician from the dispatch board is a separate action.
