The document describes an activity where participants are divided into groups. Each group is given papers and tasks to write their team number, expectations for the event, and how to measure those expectations. They then measure the event from the previous day and current day based on the expectations and measurements of another group. The goal is to practice team measurement and using data to make decisions. Management concepts are discussed that you cannot manage what you do not measure, and that what you measure is what you will get from a team. Key points are made about self-organized teams owning their own metrics and measurements.
