Scrum PSM I Practice Test - Questions Answers, Page 21

According to the Scrum Guide, a Scrum Team is cross-functional if it includes skilled individuals who together have all the skills necessary to create value each Sprint. This means that the Developers can work on any aspect of the product without depending on others outside the team. The other options are not valid descriptions of cross-functionality, as they either imply that the Developers work in silos or rely on external people (such as business analysts, architects, testers, or separate teams).

According to the Scrum Guide, the purpose of a Sprint is to produce a valuable useful Increment that meets the Definition of Done and the Sprint Goal. This means that the Developers work on items from the Product Backlog that deliver value to the stakeholders and align with the product vision.

The other option is not valid, as it implies that producing an Increment is not the purpose of a Sprint.

According to the Scrum Guide, the Developers do the work to make sure Product Backlog items conform to the Definition of Done, as they are responsible for creating a "Done" Increment that meets the Definition of Done. The other options are not valid, as they imply that the work is done by someone else outside the Development Team (such as Quality Assurance Team) or by another role on the Scrum Team (such as Product Owner or Scrum Master).

The Developers determine how many Product Backlog items they select for a Sprint, as stated in the Scrum Guide: "The Developers select items from the Product Backlog to include in the current Sprint.

The Scrum Team may refine these items during this process, which increases understanding and confidence."

A Developer becomes accountable for an item in the Sprint Backlog never as Developers on the Scrum Team share accountability for items in the Sprint Backlog, as stated in the Scrum Guide: "The Developers can select whatever items they want as long as they feel they can complete the work by the end of the Sprint. The Scrum Team is responsible for all estimates. The Product Owner may influence the Developers by helping them understand and select trade-offs, but the people who will perform the work make the final estimate."

A Scrum Master fulfills a different role than a traditional project manager, as stated in 2: "A project manager helps manage the project timeline, resources, and scope in order to meet business requirements. A Scrum Master, however, helps ensure the Scrum Team follows Scrum theory, practices, and rules. The Scrum Master is a servant-leader who helps optimize the value created by the Scrum Team."

During the Sprint, the Scrum Master's role is to facilitate inspection and adaptation opportunities as requested or needed, and to coach the team members in self-management, as stated in 3: "The Scrum Master is accountable for establishing Scrum as defined in the Scrum Guide. They do this by helping everyone understand Scrum theory and practice, both within the Scrum Team and the organization. The Scrum Master is accountable for the Scrum Team's effectiveness. They do this by enabling the Scrum Team to improve its practices, within the Scrum framework."

The timebox for the Sprint Review is four hours for a one-month Sprint, as stated in [4]: "The Sprint Review is held at the end of the Sprint to inspect the Increment and adapt the Product Backlog if needed. During the event, the Scrum Team and stakeholders review what was accomplished in the Sprint and what has changed in their environment. Based on this information, attendees collaborate on what to do next. The Product Owner explains what Product Backlog items have been "Done" and what has not been "Done"; additionally, they discuss any changes to scope or budget or potential value. The entire group then collaborates on what to do next, so that the Sprint Review provides valuable input to subsequent Sprint Planning. The Sprint Review is a working session and attendees should inspect based on facts. A Sprint Review is held at the end of every Sprint for a maximum duration of four hours for a one-month Sprint."

A Product Backlog item is considered complete when it meets the Definition of Done, as stated in [5]:

"When a Product Backlog item or an Increment is described as "Done", everyone must understand what "Done" means. Although this varies significantly per Scrum Team, members must have a shared understanding of what it means for work to be complete, to ensure transparency. This is the definition of "Done" for the Scrum Team and is used to assess when work is complete on the product Increment."
