Midway through a Sprint, a home-robot company's app team discovers that one planned feature is harder than expected, so the Developers swap it for a different Product Backlog item that still supports the same overall objective set at Sprint Planning. What Scrum element makes this kind of flexibility possible?
Select an answer to reveal the explanation.
Short Explanation
A Sprint Goal works like a destination on a map — as long as you're still headed there, you can take a different road. Because the Sprint Backlog exists to serve that one objective, the Developers can trade one item for another mid-Sprint without breaking the plan's purpose. Swap the destination itself, though, and that's a different conversation entirely.
Full Explanation
The Sprint Goal is the single objective for the Sprint that the Scrum Team commits to during Sprint Planning, and its purpose is exactly this kind of flexibility: it gives the Developers coherence and focus, encouraging the Scrum Team to work together rather than on separate initiatives, while still leaving room to negotiate the scope of work with the Product Owner as more is learned during the Sprint. As long as the swapped item still serves the same Sprint Goal, the Sprint Backlog can be adapted without asking permission for every change. The Definition of Done is a quality standard for when work counts as finished, not a mechanism for substituting items - conflating the two would let teams excuse scope changes as quality decisions. The Product Backlog is the single source of ordered work for the product, but items don't move into an active Sprint "at will"; the swap still has to respect the Sprint Goal the team already committed to. The Sprint Review is an inspection point at the end of the Sprint, not a mid-Sprint approval gate for scope changes. Caveat: if a proposed swap would change the Sprint Goal itself rather than just the means of reaching it, that's a bigger conversation than an ordinary Sprint Backlog adjustment. Operational check: before swapping an item mid-Sprint, the Developers should be able to state that the new item still serves the same Sprint Goal as the one it replaces.
