In which phase of Scrum is a Product Backlog Item expected to be refined for clarity?

The process of refining Product Backlog Items for clarity occurs throughout the Sprint process as needed. This ongoing refinement is essential because it ensures that items in the Product Backlog are well understood, with clear acceptance criteria, and are appropriately prioritized for upcoming Sprints.

Continuous refinement allows the Development Team and the Product Owner to address uncertainties around the backlog items incrementally and collaboratively. This iterative approach means that as the team gains more insights or receives feedback, they can adjust the backlog items accordingly, maintaining a clear and actionable backlog.

While Sprint Planning is an important time for discussing and elaborating on Product Backlog Items, it is not the only time these items should be refined. The refinement process is a continuous practice that helps prepare items for future Sprints, ensuring that the team is always ready to take on the most valuable and well-defined work. Engaging in this practice at various points throughout the Sprint helps in building a more robust understanding of the upcoming tasks and aligning team expectations.
