Which of the following is NOT a timeboxed event in Scrum?

In Scrum, events are designed to create regularity and to minimize the need for meetings not defined in Scrum. Each event is time-boxed to maximize effectiveness and encourage focus. The time-boxed events in Scrum are Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective.

The option referring to "Daily Planning" is not a recognized event in Scrum practice. The correct term is "Daily Scrum," which is a daily event for the Development Team to synchronize their activities and create a plan for the next 24 hours. By identifying "Daily Planning" as not being a timeboxed event, it highlights the importance of using the correct terminology and understanding the established framework of Scrum events.

In contrast, Sprint Planning, Sprint Review, and Daily Scrum are all integral parts of the Scrum framework, each serving a unique purpose and having specific time allocations associated with them. Sprint Planning is effectively when the team decides what work can be accomplished in the upcoming sprint, the Daily Scrum focuses on the daily progress and planning of tasks, and the Sprint Review is conducted to assess the work completed during the sprint. These clearly defined timeboxes help ensure that teams maintain focus and streamline their processes effectively.
