The document provides details about the Mumbai Dabbawala system of delivering home-cooked lunches to office workers. It discusses how the system started in 1890 to address the need of migrant workers. Today, over 5,000 dabbawalas use bicycles and trains to deliver 200,000 lunches daily with an error rate of only 1 in 16 million deliveries. The dabbawalas have received international recognition for their efficient supply chain and time management despite having little formal education.
