A Sprint Retrospective is focused on the process and team dynamics over the past sprint. Evaluating the Definition of Done, discussing how the team works, and team relations are all crucial aspects that affect team performance and process improvement. The value of work in the Product Backlog and arranging the Sprint Backlog for the next sprint are more appropriate topics for Sprint Planning, not the Retrospective. Hence, these topics are not suitable for discussion during a Sprint Retrospective.
