Six sigma is a system that seeks to reduce errors to less than 3.4 errors per million operations. What if I told you that it was possible to greatly exceed this standard? Can you imagine a company that delivers 2 million packages every day using 5,000 employees, and make less than one mistake every 16 million deliveries?
Can you believe that such a company has existed for over 125 years with no work stoppages? The dabbawallas of Mumbai pickup lunches from people’s homes and deliver them- still hot- to the breadwinner’s workplace 2 million times a day, and they make less than one mistake per week. They do all of it without a single piece of modern technology.
