What are issue type schemes?

As a Jira administrator, you can group issue types into issue type schemes to make it easier for your team to select the right type when creating issues in their project. Issue type schemes can also minimize the maintenance work required when administering several projects. 

An issue type scheme lets you:

• Set the available issue types for a project

• Set the default issue type and order of issue types when creating an issue

• Share the same group of issue types across multiple projects

As an example, you can set up an issue type scheme for your team of developers working in a software project. You can then add the bug and feature issue types to this scheme and apply it to any other projects that contain similar pieces of work.
