What are work items?

A work item represents an action that has to be done. That action can be a task, a bug, a feature request or any type of action your organization might need to work with. Work items are the core of the Jira applications since all the team collaboration happens around the work items and their organization.You can customize your own work types creating work item sets associated per projects, and even per permission types.

To configure the layout of the work item—which fields appear and the order they appear in—open a work item and choose Configure at the bottom-right. To find out more about configuring field layout in the work item.
