The document discusses the Mumbai Dabbawalas, a network of over 5,000 delivery workers who transport over 130,000 homemade lunches to office workers in Mumbai each day with an extremely low error rate. They achieve this through an organized system involving railway transportation of the lunchboxes, color-coded addressing systems, and a self-managed organizational structure. Their success is built on balancing key pillars of organization, management, process and culture through a flexible yet rigorous approach.
