Using project roles over groups

Maintaining a Jira instance, especially in a growing organization, can be a daunting task. There are a number of activities that can only be done by Jira administrators, so you should ensure that project administrators are also able to manage their projects as much as they can. This is especially true when more people are added to the project. There are many configurations, such as permissions, notifications, and workflows, that are based on users. When creating these configurations, if you use a Jira group instead of project roles, then your project administrators are dependent on you to add/remove people, but they do have permissions to manage their own team of users using project roles.
