1. Adobe Workfront Documentation - Create and customize system-wide statuses: "When you create a status and associate it with a group, only users in that group can use it. For users to be able to use a group status on an object, the object must also be associated with the same group." This is further detailed in the section "Create or edit a status," which explains the process of associating a status with a group.

2. Adobe Workfront Documentation - Associate objects with a group: "You can associate certain objects with a group that you manage to make group-specific items available to them. For example, if you want to use a custom form or a status that is specific to your group on a project, you must associate the project with your group."
