You've probably heard me talk about time boxes a lot by this point in these videos. We have a time box for all meetings in Scrum. Even the sprint itself is time-boxed. If your team has two-week sprints, two weeks is the timebox. A time Box is a maximum, not a recommendation. So when I say that the daily Scum is Timebox to 15 minutes, that means it takes a Maximum of 15 Minutes. Why are time boxes so important in Scrum? Back in 1955, a British historian, Cyril Parkinson, noted that work expands so as to fill the time available for its completion. This has since become known as Parkinson's Law. It means that the more time we have to do something, the longer time doing it will take. Time boxes keep team members focused and create a sense of urgency, whether in a time box meeting or a Time Box Sprint. the urgency creates a bit of pressure. Finish this within a certain amount of time. You don't want it to create so much pressure that team stress levels rise, just enough pressure to be aware of it. The 15 minute time box for a daily scrum is plenty of times for most typical seven person or so teams to synchronize their efforts. But the timebox reminds them to careful of going too deep into discussions during that meeting. One of my favorite sayings is be quick, but don't hurry. It comes from legendary college basketball coach, John Wooden. He won 10 national championships in 12 years. he was an amazing coach. By be-quick-but-don't-hurry, Coach Woodin meant to get good at a task so you can do it quickly and confidently and to do the work deliberately but without feeling rushed, especially to the point where you make mistakes. The time boxes of Scrum are all quite sufficient for doing high quality work. You want your team to execute them quickly, but without feeling hurried.
