What should a Scrum Master do when a Product Owner attends the Daily Scrum?

The most appropriate action when a Product Owner attends the Daily Scrum is to welcome their involvement as it is crucial for effective collaboration. The Daily Scrum is intended for the Development Team to synchronize their work and plan for the next 24 hours, but having the Product Owner present can enhance the process. Their presence allows for immediate clarification and feedback, thus aligning the team's efforts with the product vision and priorities.

Encouraging the Development Team to manage the situation themselves implies a level of isolation that could hinder open communication or collaboration. In contrast, integrating the Product Owner into the Daily Scrum can foster a shared understanding of progress and obstacles, allowing for a more cohesive approach to problem-solving and decision-making.

The development team benefits from the Product Owner's input during the Daily Scrum, as they can directly address any questions about priorities or needed adjustments. This can help to avoid confusion and ensure that the team remains aligned with stakeholder expectations. Allowing the Product Owner to participate promotes transparency and strengthens collaboration, which aligns well with Scrum principles and values.
