The Dabbawala system in Mumbai efficiently delivers 200,000 tiffin carriers per day using a low-tech network of over 5,000 Dabbawalas. Dabbawalas collect freshly cooked meals in the morning from homes in the suburbs, transport them into the city on local trains, and deliver them to office workers by lunchtime. They then collect and return the empty tiffin carriers back to homes in the afternoon, with an extremely low error rate of 1 in 16 million deliveries. The Dabbawala network has been in operation since 1890 and relies on teamwork, local infrastructure, and strong customer relationships rather than technology.
