How is backlog grooming done ?

Backlog grooming, or backlog refinement, is a collaborative process where the product backlog is reviewed and prioritized to ensure it is well-organized and ready for upcoming sprints. This process typically involves scheduling regular sessions, often once per sprint, where the Product Owner, development team, and sometimes stakeholders gather to assess the backlog. During these sessions, the team reviews existing items to clarify requirements, refine user stories, and establish clear acceptance criteria. Estimation techniques, such as Planning Poker, are used to assess the effort required for each item, allowing the team to understand complexity and time needed for implementation.
