Which feature allows users to follow updates in service cases within Salesforce?

Chatter feeds is the feature in Salesforce that allows users to follow updates in service cases. It provides a real-time collaboration platform where team members can post comments, updates, and share files related to specific cases. Users can "follow" a case and receive notifications whenever there are changes or new comments, making it easy to stay informed about any activity or developments.

This feature is particularly beneficial in service environments where timely communication is critical for addressing customer issues. The integration of Chatter feeds enables transparency and encourages collaboration across teams, ensuring that everyone who needs to be informed about the case is kept in the loop.

In contrast, case reports offer historical and analytical views of cases but do not facilitate immediate updates or collaboration. Notification workflows are useful for automating alerts based on predefined criteria but lack the dynamic interaction that Chatter provides. Community forums serve as platforms for broader discussions and can help users share knowledge, but they do not provide the same targeted updates for individual service cases as Chatter feeds do.
