Final answer:
User groups that are allowed to view cases refer to specific groups or individuals with permission to access and view cases based on certain criteria.
Step-by-step explanation:
For user groups that are allowed to view cases of a given type, it refers to the specific groups or individuals who have permission to access and view cases that fall under a certain category or criteria. This can be implemented through user roles or permissions set up in the system. For example, in a customer support system, there might be different user groups such as administrators, agents, and customers. Each group can have different levels of access to view or work on cases.
