Overview of Jira Cloud workflows

All Jira projects contain work items that your team can view, work on, and transition through stages of work — from creation to completion. The path that your work items take is called a workflow. Each Jira workflow is composed of a set of statuses and transitions that your work item moves through during its lifecycle, and typically represents work processes within your organization.  

In addition, Jira uses workflow schemes to define the relationship between work types and workflows. Workflow schemes are associated with a project, and make it possible to use a different workflow for different combinations of project and work types. If you need to edit or create a more advanced workflow to match how your team or organization works, you can log in as a Jira administrator with global permission to access and create your workflow.To keep things simple, use the default workflows that come with the project type you select in Jira. You can always modify or create new workflows later.
