Scrum Master (SM): Facilitates the session, ensures it's productive and stays on track.
Stakeholders (Optional): May attend for specific items requiring their input.

Key Activities:
Key Activities:
- Review and Prioritize:
The PO presents the top items in the backlog.
The team discusses the current priority and if adjustments are needed based on recent learnings or business needs.
- Clarification and Understanding:
The PO elaborates on the user story, acceptance criteria, and any relevant context.
The team asks clarifying questions to ensure a shared understanding of the requirements.
Document any new information or decisions directly in the backlog item.
- Splitting Large Items (If Necessary):
Identify backlog items that are too large or complex to be completed within a single sprint.
Collaboratively break them down into smaller, more manageable user stories.
- Adding Detail:
Ensure acceptance criteria are clear, concise, and testable.
Add any necessary notes, links to documentation, or design mockups to the backlog item.
- Estimation:
The development team provides estimates for the effort required to complete each refined backlog item (using story points, t-shirt sizes, or other agreed-upon methods).
Focus on relative sizing and team consensus.
- Addressing Dependencies and Risks:
Identify any dependencies between backlog items or potential risks that could impact delivery.
Discuss how to manage these dependencies and mitigate risks.
