  • Ceremonies: Essential meetings within the Scrum framework that facilitate team collaboration and progress tracking.

Sprint Details

Sprint Duration

  • Maximum Duration: 4 weeks

    • This is the fixed period within which a specific set of work must be completed.

  • Maximum Duration: 15 minutes each

  • Purpose:

    • To inspect progress toward the sprint goal.

    • To adapt the team's plan for the next 24 hours to make progress toward the sprint goal.

Sprint Review

  • Frequency: Once per sprint

  • Maximum Duration: 4 hours

Timebox Summary

Total Time Commitment for Scrum Ceremonies

  • Maximum Total Duration per Sprint (4 weeks): 22 hours

    • Details:

    • Sprint Planning: 8 hours

    • Daily Scrum: 15 minutes × 28 days = 7 hours

    • Sprint Review: 4 hours

    • Sprint Retrospective: 3 hours

Notable Points

  • Scaling of Daily Scrum:

    • For a maximum 4-week sprint with 28 occurrences, this results in a total commitment of approximately 7 hours, making it the second largest after Sprint Planning in total time commitment.

  • Order of Ceremonies:

    • The Retrospective always occurs after the Review and before the next Sprint Planning. This order is crucial for examination purposes.

  • Focused Interaction During Sprint Review:

    • The Sprint Review is oriented outward, engaging stakeholders in feedback and discussions about the progress and next steps.
