Managing project access and permissions in the Jira suite.

What are project roles?

Project roles are a flexible way to associate users and/or groups with particular functions and projects. Users are assigned project roles by the project lead, and these roles are used in permission schemes to assign permissions to a user.

Mapping logic of assigning user a project role in Jira Software

Project leads can grant people or groups specific access and additional roles in their project:

From your project's sidebar, select Project settings > Access.
Select Add people.
Type a name, group, or email address.
Select the person's role in your project from the Role dropdown.
Select Add.

See permission scheme for the permissions/roles

This includes the ability to edit project role membership, project components, project versions, and some project details ('Project Name', 'URL', 'Project Lead', 'Project Description').
