If Product Backlog refinement is needed, when is the ideal time for refinement to take place and who should participate? (choose the best two answers)

Question

Options

• AThe Scrum Team during the current Sprint, if they have been unable during
• BBusiness analysts in the organization should do this work for the Scrum Team 1- 2 Sprints ahead of
• CThe Product Owner must do this as essential work in Sprint O.
• DThe Product Owner takes the time between the end of one Sprint and the start
• EThe Scrum Team on an ongoing basis, defining Product Backlog items into

Explanation

A and E are the correct answers.

Options A and E align with the Scrum Guide, which states that Product Backlog refinement is an ongoing activity performed by the entire Scrum Team - not just the Product Owner - and occurs during the Sprint itself, not in gaps between Sprints or in a fictional "Sprint 0." The Scrum Team collaborates continuously to break down and clarify items so they are ready for upcoming Sprints.

B is wrong because refinement is the Scrum Team's responsibility; delegating it to external business analysts violates self-management and means the Developers lose crucial context about what they'll be building.

C is wrong on two counts: "Sprint 0" is not a recognized Scrum concept, and refinement is never solely the Product Owner's responsibility - Developers must be involved to assess feasibility and complexity.

D is wrong because there is no official time "between Sprints" in Scrum - one Sprint ends and the next begins immediately, and refinement should not fall to the Product Owner alone.

Memory tip: Think of refinement as a team sport played throughout the game - not a solo activity done before the match or only when you're losing. If you see any answer that removes Developers from refinement or places it outside the Sprint, eliminate it.
