What are sub-tasks in Jira?

Sub-tasks in Jira are defined as smaller tasks that are derived from a parent issue. This hierarchical structure allows for better management of complex issues, breaking them down into more manageable components. Each sub-task can have its own assignee, status, and details while still being directly linked to the parent issue. This relationship helps teams track the progress of the overall task more effectively since each sub-task contributes to completing the larger goal.

Sub-tasks are particularly useful in agile methodologies, where work items may need to be detailed into smaller increments to facilitate team collaboration and track progress. By having smaller, focused tasks, teams can address specific parts of a larger issue systematically and efficiently. This functionality enhances visibility and accountability within the project workflow, making it easier to manage workloads.

The other choices reflect aspects of Jira that are either not specifically related to sub-tasks or are inaccurately characterized. While option A talks about projects, sub-tasks are not standalone projects. Option C suggests sub-tasks do not connect to any parent issue, which contradicts the very definition of a sub-task. Option D discusses the organization of user stories and epics, which, while a feature of Jira, is separate from the concept of sub-tasks.
