With the introduction of Incidents, Problems - how about the existing cases and case object? How are the cases and Incidents related?

Hi John,

Cases and Incidents serve different purposes in the IT Service Management model.

A Case is generally used to manage a customer or user support request, while an Incident represents an interruption or degradation of a service that needs to be restored. 

An Incident can therefore be used to coordinate the underlying service issue, while related Cases can represent the individual user/customer reports associated with that incident. Problems can then be used to investigate the underlying root cause when the issue is recurring. 

The exact relationship and available configuration depend on the IT Service Management/Incident Management features enabled in your org.
