Scrum Events
The Sprint as container
All Scrum events occur inside the Sprint, a fixed-length iteration of one month or less. The Sprint itself is an event that creates consistency and limits risk. Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective each have a purpose and a timebox. Timeboxes are maximum durations, not targets; shorter Sprints usually scale them down.
Purposes
Sprint Planning establishes the Sprint Goal, selects Product Backlog items, and creates a plan. The Daily Scrum is a 15-minute event for Developers to inspect progress toward the Sprint Goal and adapt the plan; it is not a status meeting for managers. The Sprint Review inspects the Increment with stakeholders and adapts the Product Backlog. The Sprint Retrospective inspects how the team worked and identifies improvements.
Traps
Common traps: treating events as optional; requiring the three daily questions; turning the Daily Scrum into a report to the Scrum Master or Product Owner; treating the Sprint Review as a sign-off or demo-only ceremony; inventing Sprint Zero or a hardening Sprint; and forgetting that only the Product Owner can cancel a Sprint. Another trap is ignoring the event's purpose while focusing on its format.
Worked example
For a one-month Sprint, the maximum timeboxes are 8 hours for Planning, 15 minutes for the Daily Scrum, 4 hours for the Review, and 3 hours for the Retrospective. Rule of thumb: if a discussion belongs to another event's purpose, move it there rather than extending the current event.
