Short answer: Purpose: To keep the Product Backlog clean, prioritized, and well-understood by the team — ensuring future Sprints run smoothly.

Explain a bit more

Best practices: Held once or twice per Sprint (not an official Scrum event, but crucial). Timebox to avoid fatigue (e.g., 1 hour per week). Break down large items (epics) into smaller, actionable stories. Clarify acceptance criteria and estimate effort. Real-World Example: Before Sprint Planning, the team refines a story called “Implement Dark Mode” by discussing UI implications, dependencies, and edge cases. They split it into smaller tasks like “UI toggle”, “Theme handler”, and “User preference saving”.
