Sprint Planning comes first because the team decides which work will be completed in the upcoming sprint.
The Sprint itself begins immediately after planning.
The Daily Scrum occurs each day during the sprint.
The Sprint Review happens at the end of the sprint but before the retrospective.
The Sprint Retrospective takes place last, as it reflects on the entire sprint process.
Following the retrospective, the cycle begins anew with sprint planning for the next sprint. This creates a continuous improvement loop that is central to Scrum's effectiveness.
