Most of us have memories of playing the game of catch either as children or with our children. I really shouldn’t call it a “game” because there are no winners and losers. There is no defense because everyone is on the same side. One participant tries to deliver the ball to the other in a way that they will be able to grab and return it. The ability to catch and throw a ball is important because it is a foundation for success in many other, more complex sports. The Lean idea of catchball involves moving ideas and information from one person or team to another and, much like catch from childhood, it forms the basis for complicated decision-making and policy development.
