Replying to [Street Smart]:
Six Sigma certification is given to those organisations who has 3.4 or lesser defects in 1 million of their processes.
As pointed here that "dabbawallahs" have the chances of lunch boxes getting mixed up approximately 1 in 16 million which means that they are performing beyond excellence than as desired by six sigma certification.

And the story of "dabbawallahs" is stated as under:
Dabbawallahs: Mumbai's best managed business
Prince Charles is not the first person to show an interest in the dabbawallahs of Mumbai. In fact, the first time they actually shot to international fame was when his compatriots at the BBC did a documentary on them way back in the late 70s.
But it was in the 1990s, when management lexicon became a part of daily life, that the interest in Dabbawallahs, now synonymous with Mumbai's blurringly fast life, grew.
Today, they are feted regularly and invited to lecture students of business management. Corporate chiefs applaud them, management gurus use them as a models.
So what makes the dabbawallahs so unique? And how do they work?
At the simplest, the dabbawallahs deliver home-cooked meals to individuals at their workplaces and return empty tiffin boxes to homes and, in some cases, caterers.
For this, they charge Rs 300 to Rs 350, that is $ 6-7, a month.
The workforce of the tiffin box suppliers trust, the cooperative body that runs the system, is 5,000. Each tiffin box contains two or three containers, often carrying traditional Indian fare -- rice, curry, chapattis, and vegetables.
Housewives even send notes to their hubbies in these boxes.
The process begins early in the morning. Cooked food is picked up from houses and caterers by dabbawallahs and taken to the nearest railway station. There, the different tiffin boxes are sorted out for specific destination stations and loaded on to large, rectangular trays accordingly.
Each tray can hold up to 40 boxes. These trays then travel in local trains down to various stations. At each station, there are another set of dabbawallahs who quickly take the dabbas meant to be distributed in that area and push in dabbas meant for other stations.
A Mumbai local halts at a station for about 20 seconds or less and thus, the dabbawallahs have to work with precision and speed. During rush hour, it's a nightmare. Ask anyone who has done time on Mumbai locals.
