Final answer:
Yes, the rollout of Chatter can be restricted by profile in Salesforce.
Step-by-step explanation:
Yes, the rollout of Chatter can be restricted by profile in Salesforce.
Profiles in Salesforce determine what users can see and do in the organization. When rolling out Chatter, you can define which profiles have access to Chatter by adjusting the profile permissions.
For example, you can create a custom profile and remove the Chatter feature entirely from that profile, restricting its use to only the profiles that have been given access.
