The next Sprint begins immediately after the conclusion of the previous Sprint, as stated in the Scrum Guide: “Sprints have consistent durations throughout a development effort. A new Sprint starts immediately after the conclusion of the previous Sprint.”

The correct answer is D. 10 or fewer. According to the Scrum Guide 20201, “The Scrum Team is small enough to remain nimble and large enough to complete significant work within a Sprint, typically 10 or fewer people.” The other options are outdated or incorrect. Option A was based on the previous version of the Scrum Guide, which suggested a range of 3 to 9 developers2. Option B is too vague and does not account for the upper limit of team size. Option C is too specific and does not allow for flexibility.

According to the Scrum Guide1, 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 Developers, or the Scrum Master. A Sprint would be cancelled if the Sprint Goal becomes obsolete. This might occur if the company changes direction or if market or technology conditions change. In general, a Sprint should be cancelled if it no longer makes sense given the circumstances. But, due to the short duration of Sprints, cancellation rarely makes sense.

According to the Scrum Guide1, each event in Scrum is a formal opportunity to inspect and adapt something. These events are specifically designed to enable critical transparency and inspection. Failure to include any of these events results in reduced transparency and is a lost opportunity to inspect and adapt. All events are time-boxed events, such that every event has a maximum duration. Once a Sprint begins, its duration is fixed and cannot be shortened or lengthened. The remaining events may end whenever the purpose of the event is achieved, ensuring an appropriate amount of time is spent without allowing waste in the process. The time-box for the Daily Scrum is 15 minutes or less for a one-month Sprint. Its location and time remain constant.
