Is it possible to have multiple departments within one Jira Core project?
Use case: person A belongs to department X, person B belongs to department Y.
Person A can view/edit all department X issues, but none of the department Y issues.
Person C is manager and can see all departments.
Is that possible? Could/should I use Jira "user groups" or "project roles" for that?
