Pass the Scrum Professional Scrum Master PSM-I Questions and answers with CertsForce

According to the Scrum Guide, estimates are made by the people doing the work, which is the Development Team. The Development Team is responsible for all estimates in the Product Backlog and the Sprint Backlog. The other options are not valid guidelines for estimating work in Scrum, as they are either too prescriptive (such as requiring story points or relative units), incorrect (such as forbidding estimating or having the Product Owner make estimates), or unnecessary (such as checking estimates with the Development Team).

The correct answer is A, because the Scrum Guide states that “a Sprint can be cancelled before the Sprint time-box is over. Only the Product Owner has the authority to cancel the Sprint, although he or she may do so under influence from the stakeholders, the Development Team, or the Scrum Master.” Therefore, a Development Team cannot cancel a Sprint by itself.

According to the Scrum Guide, two things that the Scrum Team should do during the first Sprint are building at least one piece of valuable functionality and creating at least one valuable, useful Increment. These are the goals of every Sprint, regardless of its order. The other options are not things that the Scrum Team should do during the first Sprint, as they are either out of scope (such as defining major product features and a release plan architecture or making a plan for the rest of the project) or unnecessary (such as analyzing, describing, and documenting requirements for subsequent Sprints).

The correct answers are C and E, because these statements explain what “Done” means. No work left from the definition of “Done” means that all Product Backlog items selected for a Sprint meet the quality criteria agreed upon by the Scrum Team. All work to create software that is ready to be released to end users means that the Increment is potentially releasable at any time during the Sprint.

The correct answers are A and B, because these are true about the Product Owner role. The Product Owner is one person, not a committee or a team, who is accountable for ordering the Product Backlog and maximizing the value of the product. The Scrum Guide states that “the Product Owner is responsible for maximizing the value of the product resulting from work of the Development Team. How this is done may vary widely across organizations, Scrum Teams, and individuals. … For the Product Owner to succeed, the entire organization must respect his or her decisions.”

According to the Scrum Guide, a Development Team is cross-functional if it has all the skills to create a potentially releasable Increment by the end of every Sprint. The other options are not indicators of cross-functionality, as they are either specific practices (such as pair programming or test driven development) or irrelevant factors (such as conflicts within the team or ability to perform every task).

According to the Scrum Guide 1 , ordering Product Backlog items is solely up to the Product Owner’s discretion. The Product Owner orders items in the Product Backlog to best achieve goals and missions. To do this, they optimize value by considering various factors such as cost and benefit, risk, dependencies, date needed, etc. The Product Owner is responsible for maximizing the value of the work the Development Team does.

According to the Scrum Guide 1 , an Increment is a concrete stepping stone toward the Product Goal. Each Increment is additive to all prior Increments and thoroughly verified, ensuring that all Increments work together. In order to provide value, an Increment must be usable. Multiple Increments may be created within a Sprint. The sum of the Increments is presented at the Sprint Review thus supporting empiricism. However, an Increment may be delivered to stakeholders prior to the end of the Sprint. The Sprint Review should never be considered a gate to releasing value. Therefore, in order to turn Product Backlog items into an Increment of potentially releasable product functionality, the Development Team should have all the skills needed.

The correct answer is B, because when multiple teams work together on the same product, they should not maintain separate Product Backlogs. The Scrum Guide states that “multiple Scrum Teams often work together on the same product. One product goal unites them. Therefore, they must mutually define and comply with a definition of ‘Done’ that applies to their combined work product. … Multiple Scrum Teams working on the same product use the same Product Backlog.”
