The document describes a game called "Kata Bingo" that can be played during meetings to encourage the use of lean principles. The game awards points for behaviors aligned with the Improvement Kata and Coaching Kata, such as proposing experiments, setting dates to review experiments, and acknowledging uncertainty. Players track their points on a provided form, with the goal of being the first to reach 100 points and shout "BINGO!". The game is intended to help shift meetings toward more fact-based discussions focused on taking steps and conducting experiments rather than speculation.
