Ball point challenge instructions (30 minutes)
• The objective of the Ball Point game is to get as many balls through the team as possible within two minutes. Each
ball must be touched at least once by every team member and must end with the same person with whom it began.
After two minutes the team is allowed an additional minute to discuss the process and how it could be improved. The
game is played a total of five times.
• Game play.
• The flow of the game consists of several iterations of play immediately followed by a retrospective. By doing several
iterations you’ll be able to see the team increase the performance following the feedback from the retrospective. It
can be quite a dramatic increase, and teams love it! Here’s the process for the game play.
• Allow the team two minutes of preparation time to determine how they will organize themselves.
• Get an estimate from the team of how many balls they can pass through the system.
• Run a two-minute iteration.
• Track the number of balls per iteration, for each ball that drops is -3 (defects are expensive).
• Allow the team one minute to discuss how to improve the process.
• Repeat for five iterations. Make the fifth iteration a challenge. If you need to, make up some statistic such as “The
world record is 200 points. Can you beat that?”
• At the conclusion of the exercise, debrief for five to ten minutes. There are a number of interesting points that are
worth talking about. Firstly, it’s worth mentioning the Deming Cycle. Secondly, it’s worth pointing out that every
system has a natural velocity. And finally, it’s worth discussing “flow” and the necessary criteria for it.
