What is a good option in scrum when a Product Owner is overworked?

When a Product Owner is overworked, a good option is to delegate some of their responsibilities to a team member or a Business Analyst who can assist with backlog management and stakeholder communication. Additionally, the team can implement regular backlog refinement sessions to ensure that priorities are clear and manageable. It may also be beneficial to reassess the scope of the current work and adjust the team's commitments to align with the Product Owner's capacity. Lastly, consider involving the Scrum Master to help facilitate processes and alleviate some of the Product Owner's burdens.
