While it is the JIRA administrator's responsibility to create new projects and manage their settings, it is ideally each project administrator's responsibility to maintain his/her own projects.
Each project has an administration page that allows project administrators to make adjustments to the project. For example, you can change the project's name, select what issue types will be available for the project, and manage a list of components within the project. You need to be a project administrator in order to access this. We will discuss groups, roles, and permissions in Chapter 8.
