What is the role of the Product Owner in refining the Backlog during a Sprint?

The Product Owner:

• Continuously refines the Product Backlog — even during a Sprint.
• Works with stakeholders and the team to break down large items.
• Clarifies acceptance criteria.
• Re-prioritizes based on new insights.

Example:

Mid-Sprint, the PO learns from sales that customers are struggling with onboarding. They

update the backlog by splitting “User Onboarding Flow” into smaller, clearer stories for the

next Sprint.
