Zoho CRM User Groups
In Zoho CRM, you can create user groups (set of users) to manage a set of common records. Every group can consist of members that are grouped based on the users, roles (with/without subordinates), territories (with/ without sub-territories) and groups. These combinations allow you to share common records through data sharing rules.
