When the
ProductOwner is ready for a feature to be developed, it is moved from the
ProductBacklog to a
SprintBacklog. So at first its estimate may be large and unwieldy.
So, at the beginning of the
ScrumSprint, during
SprintPlanning, such a feature might be split into multiple, smaller items for implementation. In this way, the feature description and estimate are better defined, and sometimes new tasks/features are discovered.
Likewise, during a Sprint, if entirely new tasks are discovered, they can be added to the
SprintBacklog. It is also possible, however, that a new task
not related to the
SprintGoal is tossed back into the
ProductBacklog, to be prioritised by the
ProductOwner according to business priorities.
