Summary

There are situations in some organizations, where users don’t want to use team-managed projects. Users need the ability to disable Team-managed projects for all Jira users, including admins.

Jira Administrators can create projects (Company and Team-Managed) as well as make changes to the Schemes used by Company Managed Projects.

In order to provide more flexibility, there is the specific Create team-managed projects permission, which will allow anyone with that permission to create the Team-Managed projects, without the need for elevated Jira Admin access.

You can remove this permission via the Global Permissions settings in the System settings as shown below:
