The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team. A major part of that accountability is working with stakeholders and making sure the Scrum Team is focused on the most valuable work.
Why A is correct:
A Product Owner must actively engage with stakeholders and ensure transparency around the product. While the Scrum Guide does not prescribe a specific reporting style, it clearly places the Product Owner in the role of managing value, aligning stakeholder needs, and making sure the Product Backlog reflects what is most important. Communicating product direction, priorities, and progress to customers and stakeholders is a key part of that responsibility.
Why D is correct:
This is one of the strongest descriptions of Product Owner work. The Product Owner collaborates with customers and stakeholders to understand needs, determine value, and order the Product Backlog accordingly. The Product Owner is accountable for effective Product Backlog management, which includes developing and explicitly communicating Product Backlog items and ordering them to best achieve goals.
Why B is not the best answer:
The Scrum Guide does not require User Stories. Scrum only requires that Product Backlog items be clear enough and ordered appropriately. User Stories are a common technique, but they are not mandated by Scrum. Therefore, “writing clear, transparent User Stories” is not an official Product Owner duty as defined by Scrum.
Why C is incorrect:
The Product Owner should be available to support clarity and decision-making, but Scrum does not say the Product Owner should be with Developers all the time. Scrum promotes self-managing teams, and the Product Owner is one member of the Scrum Team, not a constant on-demand requirement clarifier sitting with Developers at all times.
