How does PBR work?

PBR, or Product Backlog Refinement, is a key activity in the Scrum framework. It involves the continuous process of breaking down and refining product backlog items (PBI) into smaller, more precise tasks. This ensures that the team has a clear understanding of the work to be done and can commit to delivering specific items in each Sprint. PBR also includes estimating the effort required for each PBI and prioritizing the backlog to align with the product’s goals and vision.
