Scrum Increments

Correct Answer: The Scrum master should advise the Product Owner that these changes can be considered for the next sprint.

In the principles of Scrum, changes in the middle of the sprint are discouraged. This is because the team commits to a set of work items for a specific period (the sprint). The main purpose is to have a stable understanding of what is to be accomplished in the sprint. Hence, the Scrum master should advise the Product Owner to consider these changes for the next sprint. The other options are not ideal because: Allowing the Product Owner to include new features disrupts the current sprint plan, thus goes against the principles of Scrum. Cancelling the current sprint to start a new one is not an ideal practice and only recommended in extreme cases, as this can lead to waste of resources and effort. Ignoring the Product Owner's demand not only goes against the principles of Scrum, which foster collaboration and respect among team members but also may lead to a potential dispute or conflict.

Correct Answer: At the end of every sprint

In the Scrum framework, a potentially releasable increment should be available at the end of every sprint. This is because, one of the key principles of Scrum is 'Inspect and Adapt'. Providing a potentially releasable increment at the end of every sprint allows the team to review the product, gather feedback and make necessary improvements for the next sprint. It's not entirely up to the product owner's decision on when to make an increment available, as choice 'When the product owner decides' suggests. It's also not possible to wait until all backlog items are cleared ('When the developers have cleared all the backlog items'), given that product backlogs are continually groomed and updated. 'At the middle of the sprint' fails to take into account that sprints are timeboxed development cycles designed to produce a potentially releasable product increment, typically at the end of the cycle.

Correct Answer: The Scrum Master should remind the Product Owner about the rules of Scrum and explain that changes can only be made before the start of a Sprint.

In Scrum framework, once a Sprint has begun, its duration and the scope of work are fixed and should not be changed. The Product Owner cannot add additional items to an increment in the middle of a Sprint. If they do, the Scrum Master should gently remind the Product Owner about the rules of Scrum and explain that changes can be made only before the start of a Sprint, when planning the work to be performed. This is designed to allow the team to focus on achieving the goals of the Sprint and deliver potentially shippable increment. Allowing the Product Owner to add new items in the middle of a sprint ('The Scrum Master should allow the Product Owner to add the items.') disrupts the team's work and violates Scrum rules. Ignoring the request ('The Scrum Master should ignore the request, avoiding unnecessary conflict.') does not address the issue effectively, instead, it can lead to misunderstandings and future conflicts. Assuming responsibility and integrating the items into the increment ('The Scrum Master should assume responsibility and integrate the additional items into the increment.') is not within the Scrum Master's responsibilities, it's also against the Scrum rules which specify that the sprint backlog is not to be changed during the sprint.
