  A bit of tech now
  

Their system of sorting and daily delivering thousands of lunch Dabbas in Mumbai is world renowned. Their homespun code was studied and was classified Six Sigma by management gurus- so low is their error count that uses Indian brain as software and a piece of chalk as hardware.

PTI reports today that they are beginning to use technology now: mobiles and a computer. Why, was the old system failing? Not at all. They use tech only for marketing their service. Now people can use SMS and the Dabbawalas' web-site to join or order their meals. Chalk is still their core hardware.
