The Sprint Backlog items and the Sprint Goal do not change after the Sprint Planning and the Development Team will focus on delivering an Increment of “Done” based on this plan.
Is the above statement correct? Does the sprint backlog items never change, what if the PO recognizes that one of the PB items is obsolete? Will the development team discard the changes that were made based on that obsolete item? doesn't it mean that sprint backlog items can be changed?
