Scrum Teams conduct Product Backlog Refinement in various ways. Developers might refine items individually or in small groups, with or without the Product Owner. Additionally, the entire Scrum Team might meet each Sprint to carry out Refinement together, fostering collaboration and transparency.
Many Scrum Teams develop a Workflow that combines these approaches, ensuring each Product Backlog item benefits from multiple perspectives. This flexible approach allows the team to adapt their practices to best suit their needs and maintain an effectively refined Product Backlog.
