Create a User Story Dependency

User Story Dependencies

Sometimes a user story requires the delivery of another user story or its functionality before it can be implemented. For example, a user story that provides access to online help depends on the completion of the user story for a Help button. A user story can also be depended on by another story.

A dependent story is the story that depends on another story.
A story dependency is the story on which another story depends.

The user story dependency must be in the same product.
