Workflows help you organize how your team handles repeating tasks. You can use issue statuses (Your Avatar -> Administration -> Issue statuses) to define the different steps a task can undergo from creation to completion (e.g., New, Assigned, Ready for review, Reviewed, etc.).
In order to use a newly-created issue status, ensure that the project’s membership role has a workflow that allows the desired status transition.
To edit workflow permissions:
In the top menu bar, click on Your Avatar
Navigate to Administration -> Workflow.
Select your role in the project and the tracker being used for the issue.
If you would like to assign a newly-created status, clear the “Only display statuses that are used by this tracker” check box.
Click Edit.
Review and modify status transitions as needed.
