The document discusses Bruce Lee's journey in martial arts and how it relates to the Kanban method of continuous improvement. It describes how Lee rejected traditional martial arts styles and teachings, instead focusing on core concepts and starting from first principles. It notes how Lee emphasized training with live opponents to enable closed-loop learning and the evolution of techniques. This is compared to traditional martial arts forms which do not facilitate adaptation. The document then discusses how the Kanban method similarly rejects traditional change approaches, instead focusing on evolutionary change through small experiments and avoiding resistance to change. It emphasizes visualizing and limiting work, managing flow, and establishing feedback loops to continuously improve processes.
