You can now use GitHub Projects at the Organization level. All users in your Organization will have access to its Projects, so you and your team can plan and manage work across repositories. With organization-wide Projects, everyone can see what's already in motion and work together without duplicating efforts.
Organization-wide projects can contain issues and pull requests from any repository that belongs to an organization. If an organization-wide project includes issues or pull requests from a repository that you don't have permission to view, you won't be able to see it.
