Which feature helps to automatically allocate a critical, high priority, service request to the appropriate assignment group or team member?

'User Policy' is not a standard ServiceNow feature used for automatic task assignment.

UI Policies dynamically change the appearance or behavior of fields on a form but do not perform automatic record assignment.

Predictive Intelligence uses machine learning to suggest assignments, but the actual automatic allocation is performed by an underlying mechanism, often an Assignment Rule, based on these suggestions or other conditions.

Assignment Rules automate the process of populating the 'Assigned to' and 'Assignment group' fields on tasks, ensuring that incoming requests are automatically directed to the correct team or individual based on criteria like priority, category, or other form fields.
