What part of the capacity of the Development Team does Product Backlog refinement usually consume?

Product Backlog refinement is an essential ongoing activity in Scrum that includes breaking down high-level items into smaller, more manageable pieces, estimating the effort required, and ensuring that the items are clearly understood and aligned with the product goals. The estimation of how much capacity the Development Team should allocate for this activity is often a matter of practical experience derived from industry norms.

The correct choice, suggesting that the capacity consumed for Product Backlog refinement should not exceed 10%, aligns with established best practices, which indicate that refining the backlog is a necessary part of maintaining a healthy and actionable Product Backlog without overwhelming the team with too much overhead. Allocating around 10% of the team's capacity ensures that the team can effectively prepare for upcoming Sprint Planning without impacting their ability to deliver the intended work during the Sprint.

Furthermore, having a balanced approach to refinement helps teams focus on delivering value while maintaining clarity in their work, making sure they spend adequate time on direct development activities as well. This approach leads to a more organized workflow and reduces the chances of miscommunication or misunderstandings regarding the Product Backlog items.

Thus, indicating that the time dedicated to refinement should not exceed 10% supports Agile principles by promoting continuous improvement while allowing the team to concentrate primarily on delivering functional
