What event begins immediately after the conclusion of the previous one?

The event that begins immediately after the conclusion of the previous one is the Sprint. In Scrum, a Sprint is a time-boxed period during which a specific set of work is completed and made ready for review. Each Sprint starts right after the previous Sprint ends, creating a continuous cycle of development.

Following a Sprint, there is typically a Sprint Review and Sprint Retrospective, but these are separate events that occur after the Sprint. The Daily Scrum takes place within the Sprint itself, occurring every day, and therefore does not mark the transition from one event to another; rather, it fits into the daily rhythm of the Sprint. Thus, the unique characteristic of the Sprint is that it seamlessly connects to the next Sprint without any intervening breaks, thereby encapsulating the iterative nature of Scrum.
