Groups are collections of ServiceDesk users. The use of groups lets you assign permissions more efficiently and helps simplify the ongoing administration of ServiceDesk permissions. Instead of assigning permissions to each user individually, you can specify the permissions for a group. The permissions for a group are valid for each user who is a member of that group. ServiceDesk permissions are almost always granted at the group level rather than at the user level.
You can copy permissions from another group and assign them to the new group. If you do not copy the permissions from another group, you must assign the permissions to the new group in a separate task.
