What happens during backlog refinement sessions? Select the item that is NOT part of the usual activities.

• A. Estimate story sizes
• B. Clarify acceptance criteria
• C. Ensure the backlog has a target of 2 sprints worth of stories ready for the new sprint
• D. Reflect on what went well and what could be improved for the next sprint

Answer: (D)

Backlog refinement sessions are about shaping and preparing backlog items so the team can pick them up in upcoming sprints. During refinement the team estimates effort by sizing stories, and they clarify acceptance criteria so there is a clear understanding of what “done” means. They also check that there’s enough high-priority work ready for sprint planning, often aiming for a portion of the backlog to be ready for the next couple of sprints. The activity of reflecting on what went well and what could be improved for the next sprint is typically done in a sprint retrospective, not during backlog refinement. Retrospectives focus on process improvement and learning from the completed sprint, while backlog refinement concentrates on future work and readiness.
