Issue Types

An issue can be categorized into task (or action), defect (or bug), and feature (or enhancement).

You can create these types of issues:

Issue Type	Description
Task	Indicates a task, which means an action is required. A Task type issue could be an action such as a piece of work that must be completed within a certain time, or a simple function to be performed.
Defect	Indicates a defect, which means a bug or a fault in the product. This is the default issue type. A Defect type issue could be an error or a flaw that prevents the software from working correctly, or creates an unexpected output.
Feature	Indicates a new feature or an enhancement request. A Feature type issue could be a request to add a new aspect or characteristic to the product, or enhance an existing feature.
Epic	Indicates an Epic, a unit of work that cannot be completed in one sprint. It can contain any other types of sub-issues necessary to complete that work. An Epic is a larger issue, typically with multiple smaller sub-issues or stories. An epic can span multiple sprints and must have sub-issues (as stories or other issues).
Story	Indicates a Story, a sub-issue of a parent epic issue. The story issues of an epic issue can be allotted to different sprints in an Agile board.
