According to the Scrum Guide1, the Sprint Review is an informal meeting at the end of the Sprint, where the Scrum Team and stakeholders collaborate about what was done in the Sprint. Based on that and any changes to the Product Backlog during the Sprint, attendees collaborate on what to do next. The Product Owner explains what Product Backlog items have been “Done” and what has not been “Done”; the Development Team discusses what went well during the Sprint, what problems it ran into, and how those problems were solved; and the Development Team demonstrates the work that it has “Done” and answers questions about the Increment. The entire group collaborates on what to do next, so that the Sprint Review provides valuable input to subsequent Sprint Planning. The Sprint Review is mainly an inspect and adapt opportunity for the Scrum Team and stakeholders.

An example of an Increment is a valuable, useful set of product features, as stated in [4]: “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, each Increment must be usable.”

According to the Scrum Guide1, collaboration between the Product Owner and Developers is essential for creating valuable products. The Product Owner is accountable for maximizing value resulting from work by Developers. Developers are accountable for creating a plan for the Sprint, which includes selecting items from Product Backlog that they can complete within a Sprint. 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. Therefore, two valuable actions for a Scrum Master to take if the Product Owner is not collaborating with the Development Team during the Sprint are:

• Bring up the problem in the Sprint Retrospective, where the Scrum Team can inspect how they worked together and create a plan for improvements.
• Coach the Product Owner in the values of Scrum and incremental delivery, and help them understand their role and responsibilities in collaborating with Developers.

The other options are not valuable actions, as they may undermine trust, respect, and self-organization within the Scrum Team.

The correct answers are B and D, because the length of the Sprint should be chosen based on the level of uncertainty over the technology to be used and the risk of being disconnected from the stakeholders. The Scrum Guide states that “Sprints have consistent durations throughout a development effort. A new Sprint starts immediately after the conclusion of the previous Sprint. Sprints enable predictability by ensuring inspection and adaptation of progress toward a Sprint Goal at least every calendar month. When a Sprint’s horizon is too long the Sprint Goal may become invalid, complexity may rise, and risk may increase.”
