What is a project role in JIRA, and how does it impact project administration?

In JIRA, a project role defines a set of permissions that determine what actions a user with that role can perform within the project. These permissions may include creating, editing, assigning, or transitioning issues, as well as administering the project settings. Project roles play a crucial role in project administration by allowing administrators to control access and responsibilities for different stakeholders. By assigning appropriate roles to users or groups, the administrator ensures efficient collaboration and adherence to project workflows and policies.
