If the Product Owner is absent, having enough refined and ready Product Backlog items ensures that the Developers are not blocked and can continue working. Higher-ordered items, which are usually more detailed, provide a buffer that helps maintain progress even in the Product Owner’s absence.
This preparation is crucial for the continuous Flow of work and helps prevent delays. It also demonstrates the importance of having a well-maintained Product Backlog that can support the team’s activities regardless of individual availability.
