Scrum PSM-I - Professional Scrum Master I

The correct answer is C, because as soon as possible in the Sprint, the Development Team should work with the Product Owner to remove some work or Product Backlog items if they realize they have selected too much work to finish in the Sprint. The Scrum Guide states that “the Development Team may renegotiate the selected Product Backlog items with the Product Owner. If the Development Team realizes it has too much or too little work, it may renegotiate the selected Product Backlog items with the Product Owner. The Development Team may also invite other people to attend to provide technical or domain advice.”

According to the Scrum Guide1, there are five values that guide decisions within Scrum teams:

Commitment

Focus

Openness

Respect

Courage

By not building Product Backlog items that have low business value, Scrum teams exhibit respect for their stakeholders and customers, as they deliver what is most valuable and relevant for them. They also exhibit focus, as they concentrate on what matters most for achieving their Product Goal and Sprint Goal. They also exhibit courage, as they are willing to say no to low-value work and face possible conflicts or disagreements.

The correct answer is A, because the role of management in Scrum is to facilitate the Scrum Teams with insights and resources that help them improve. The Scrum Guide states that “the organization respects their self-organization by not telling them how they should do their work.” Therefore, management should support the Scrum Teams by providing them with an environment that fosters collaboration, learning, and innovation.

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).

According to the Scrum Guide1, 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.

 According to the Scrum Guide, the Daily Scrum is held at the same time and same place to reduce complexity and promote consistency. The other options are not valid reasons for holding the Daily Scrum at the same time and same place, as they are either irrelevant (such as naming the place) or incorrect (such as being demanded by the Product Owner or booking rooms in advance).

The correct answer is D, because this statement best describes the Sprint Review. The Scrum Guide states that “a Sprint Review is held at the end of the Sprint to inspect the Increment and adapt the Product Backlog if needed. During the Sprint Review, the Scrum Team and stakeholders collaborate about what was done in the Sprint.” Therefore, the Sprint Review is when the Scrum Team and stakeholders inspect the outcome of a Sprint and figure out what to do next.

The correct answer is B, because the Scrum Guide states that “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.” Therefore, new work or further decomposition of work can be added to the Sprint Backlog as soon as possible after they are identified by the Development Team.

According to the Scrum Guide, the Sprint Retrospective is an opportunity for the Scrum Team to inspect itself and create a plan for improvements to be enacted during the next Sprint. The topics that are appropriate for discussion are those that relate to how the team does its work, such as team relations, Definition of Done, and processes, tools, communication, collaboration, quality, etc. The other options are not appropriate topics for discussion in a Sprint Retrospective, as they belong to other Scrum events (such as arranging the Sprint Backlog for the next Sprint in the Sprint Planning or evaluating the value of work in the Product Backlog in the Sprint Review).

According to the Scrum Guide, when multiple Scrum Teams are working on the same product, they should integrate their Increments every Sprint, in order to accurately inspect what is done and ensure that there is no technical debt or unfinished work at the end of each Sprint. The other options are not valid, as they imply that integration can be skipped, delayed, or done only for some teams, which is not consistent with Scrum values and principles.
