If a work queue is acquiring too many tasks, and the processing rate is too slow to meet your business needs, you can add more users to a queue.
Users with the queue_admin or queue_manager role can assign users, and groups to queues.
To add a user or group to a work queue:
Click the Work Queue Monitor node or select Work Queue Management > Work Queues.
Navigate to the active work queue.
Click the queue’s number users link in the Active Users column.
Select File > Add Member.
Select the user or group, and click the arrow. Users must be assigned to the role queue_processor or queue_advance_processor to appear in this list.
Click OK
Select skills for the processor that are used in work assignment matching.
Click OK.
