A new Product Owner asks the Scrum Master to help them separate what they must answer for from what belongs to the Developers. Which TWO of these are part of the Product Owner's accountability for effective Product Backlog management?

Professional Scrum Master I, objective 3. Managing products with agility medium

Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.

Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.

The options

Choose 2.

Correct Ordering the Product Backlog items

Correct. Ordering is named directly as part of effective Product Backlog management, and it is the decision the whole accountability turns on.

Not correct Sizing the Product Backlog items so the order reflects cost as well as value

Wrong. Sizing belongs to the Developers who will be doing the work; a Product Owner may influence them by helping them understand and select trade-offs, but the size is not theirs to set.

Not correct Planning how the selected items will be turned into an Increment that meets the Definition of Done

Wrong, and it is the plausible one because it happens with the Product Owner in the room at Sprint Planning. How the work gets done is at the sole discretion of the Developers.

Correct Ensuring that the Product Backlog is transparent, visible and understood

Correct. The Guide lists this alongside ordering, and it is what makes the ordering usable — an order nobody can see or understand decides nothing.

Why

The Guide gives four elements of Product Backlog management: developing and explicitly communicating the Product Goal, creating and clearly communicating items, ordering them, and keeping the backlog transparent, visible and understood. Read the list and notice what is missing — sizing, and any say over how the work is done. That boundary is the one the paper tests: the Product Owner owns what and in which order, the Developers own how big and how.
