What is the role of Queues in Salesforce?

Hi,

Queues help you prioritize, distribute, and assign records to teams who share workloads. You can access queues from list views, and queue members can jump in to take ownership of any record in a queue. Queues are available for cases, leads, orders, custom objects, service contracts, and knowledge article versions.

You can add a record to a queue manually by changing the record’s owner. Or, an assignment rule can add cases or leads to a queue based on criteria, such as Origin equals Email. Records remain in a queue until they’re assigned an owner, or a queue member volunteers to own them. Any queue members or users higher in a role hierarchy can take ownership of records in a queue.

Some examples of queues include lead queues for distributing and sharing leads among salespeople assigned to specific regions, such as western or eastern. Case queues for distributing and sharing cases among support agents assigned to different service levels, such as gold or silver service. Knowledge article version queues for distributing new versions of articles to people who can translate articles into specific languages.
Thanks
