Refining the backlog before the Sprint allows the team to identify and clarify the requirements, breaking down larger items into smaller, more manageable tasks. This ensures that the Product Backlog is well-organized, prioritized, and aligned with the overall project goals before the formal Sprint Planning meeting occurs.
