As a Project Level Admin would changing or adding workflows within my project, affect other projects

[Bhavi Patel]

If changing a workflow in my project, does affect another project's workflows, is there a way that the global jira admin can allow project admins to make changes and adjust their own workflows without impacting other projects?

Hi, the short answer:

If you're on Team managed project there shouldn't be a problem. 

If you're on Company managed project, you would see with how many projects your workflow is being shared.
