管理者のロールはチーム管理対象プロジェクトでどのように変更されましたか?

Only Jira admins can create company-managed projects. They configure schemes. Schemes are configurations of screens, work types, workflows, statuses, and more across all company-managed projects in your Jira instance. Project admins can then make changes to project-specific settings, such as request types, portal settings, and email settings. These changes to the configuration will only affect that project.

In team-managed, all team members can create team-managed projects. The person who creates the project becomes a project admin, and can configure the project without schemes set up by a Jira admin impacting the project (there are no schemes in team-managed projects). Learn to manage and administer team-managed service projects.
