How much time is required after a Sprint to prepare for the next Sprint? (choose the best answer)

The Scrum framework prescribes a continuous flow of development through consecutive Sprints. The conclusion of one Sprint, marked by the Sprint Retrospective, is immediately followed by the start of the next Sprint with its Sprint Planning event. There are no gaps or intermediate phases between Sprints. This continuous cycle maintains momentum, provides a consistent rhythm for the Scrum Team, and ensures that opportunities to inspect and adapt are never delayed. Activities like backlog refinement and planning for the next Sprint occur during the current Sprint, not in a break between them.

A. The Scrum Guide does not define any break between Sprints. Sprints are designed to be contiguous to maintain a consistent cadence and flow.
B. Product Backlog refinement is an ongoing activity that occurs during a Sprint to prepare for future Sprints, not in a gap between them.
C. All work required to create a "Done" Increment, including testing, must be completed within the Sprint. Spilling work over violates this core principle.
E. Since options A, B, and C describe anti-patterns and contradict the Scrum framework, this option is incorrect.
