Professional Scrum Product Owner (PSPO I): PSPO-I

Correct Answer: A

Correct Answer: D

The work to make sure Product Backlog items conform to the Definition of Done is done by the Developers. This is because:

The Developers are accountable for creating a "Done" Increment in every Sprint. They must ensure that every Product Backlog item they work on meets the Definition of Done before it is considered complete. The Definition of Done is a

formal description of the state of the Increment when it meets the quality measures required for the product. It is a shared understanding among the Scrum Team and the stakeholders of what "Done" means for any Product Backlog item that

is selected for a Sprint. The Developers are self-managing professionals who organize and manage their own work. They decide how to best accomplish their work, rather than being directed by others outside the Scrum Team.

Other options, such as the Product Owner, the Quality Assurance Team, the Scrum Team, or the Scrum Master, are not responsible for making sure Product Backlog items conform to the Definition of Done. They may have different roles and

accountabilities in Scrum, but they do not do the actual work of creating a "Done" Increment.

Correct Answer: B

Sprint 0 is a term that some organizations use to describe a phase of work before the first official Sprint, where they do some upfront planning, design, architecture, or analysis1. However, this term is not consistent with the Scrum framework,

which does not prescribe any pre-Sprint activities or phases2. Scrum starts with a Product Backlog that contains at least one valuable and feasible Product Goal, and enough Product Backlog items to initiate the first Sprint[3][3]. The Product

Owner is accountable for maximizing the value of the product and the work of the Developers, and for managing the Product Backlog4. The Product Owner does not have any specific accountability during Sprint 0, because Sprint 0 is not a

part of Scrum.
