Professional Scrum Master PSM-I Passing Score

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 best approach for Scrum Teams in order to produce valuable Increments is to have each Developer work on the component where they feel that they can contribute. This means that the Developers can self-organize and collaborate effectively to deliver a valuable Increment that meets the Definition of Done and the Sprint Goal. The other options are not valid approaches, as they either imply that the Developers work in silos or rely on external people (such as developing functionality from beginning to end, working on an independent set of components, or working only as an independent layer of the system).

The correct answer is D, because the recommended size for a Development Team is 3 to 9 members. The Scrum Guide states that “fewer than three Development Team members decrease interaction and results in smaller productivity gains. Smaller Development Teams may encounter skill constraints during the Sprint, causing the Development Team to be unable to deliver a potentially releasable Increment. Having more than nine members requires too much coordination. Large Development Teams generate too much complexity for an empirical process to be useful.”

Sprint Backlog is owned by the Development Team. The Scrum Guide states that “the Sprint Backlog is the set of Product Backlog items selected for the Sprint, plus a plan for delivering the product Increment and realizing the Sprint Goal. … The Development Team modifies the Sprint Backlog throughout the Sprint, and the Sprint Backlog emerges during the Sprint. This emergence occurs as the Development Team works through the plan and learns more about the work needed to achieve the Sprint Goal.”
