The Time-Box

1. Scrum Events are Timeboxed i.e. they have a maximum duration not to be exceeded.
2. A Sprint can be a maximum of 1 month and a minimum of 1 week.
3. Scrum Teams choose the length of the Sprint.
4. For a 1 month Sprint
   • Sprint Planning = 8 hours
   • Sprint Review = 4 hours
   • Sprint Retrospective = 3 hour
   • Daily Scrum is always 15 minutes

1. When a Sprint is less than 1 month, the other events are usually proportionately shorter, but this is not a requirement.
2. All Events can vary in length based on the length of the Sprint, except the Daily Scrum.
3. All Scrum Events, besides the Sprint, can end early when the purpose of the event is achieved.
