After playing this, a group discussion about what some of the memorable messages were * Run the Ball game as described on the slides: * 4 sprints in total * Radiate and capture estimates vs actuals * Look for trends in improved accuracy of estimation and increased overall velocity * At the end of Sprint 2, suggest each team does a review of other teams to see if they can learn new techniques from watching others in action * At the end of Sprint 3, calculate the team's overall velocity. Challenge them to triple this. Ask what would help bring up the overall velocity (answer is smaller teams). Run a 4th sprint where group can self organise into smaller teams (agree a team is more than one person) * Debrief the learnings
