Question 7

During the Sprint Review meeting, the Scrum Team demonstrates complete and incomplete Product Backlog Items and discusses what to do next.

  1. True
  2. False

Correct Answer: B.
Explanation: According to the Scrum Guide, only "done" work should be demonstrated in the Sprint Review. Demonstrating incomplete work may create the impression that it is complete and ready for release.


Question 8

The Scrum Team meets with the Stakeholders at the end of the Sprint. What should the Product Owner do if a Product Backlog Item is only partially done?

  1. Inspect the work with the Stakeholders and release the acceptable parts to gather market feedback
  2. Consult with the Developers, and if the work seems good enough, release it and add any issues to the Product Backlog
  3. Return the incomplete work to the Product Backlog without releasing it

Correct Answer: C.
Explanation: Incomplete work is not considered releasable. Any unfinished item should be moved back to the Product Backlog for future refinement and potential inclusion in subsequent Sprints.

  2. Yes, because the Product Owner already reviewed the features before the meeting.
  3. No, because Stakeholders cannot give valuable feedback without experiencing the actual Increment.

Correct Answer: C.
Explanation: The Sprint Review is intended as a hands-on inspection of the product, allowing stakeholders to interact directly with the Increment to provide meaningful feedback.
