The lunch box that finds its own desk: how Mumbai’s dabbawalas sort 200,000 meals a day

By Porter Lang

A lunch box leaves a kitchen in the suburbs in the late morning and is on a desk in a south Mumbai office by lunchtime. Nobody scans it. It carries no label that a stranger could read. It carries marks, and the marks are the system.

This piece is about how that system is described, and about one famous claim attached to it that does not stand up as well as the legend suggests.

Scale

Wikipedia estimates that 4,500 to 5,000 dabbawalas move 175,000 to 200,000 lunch boxes each day. The dabbawalas’ own site gives about 5,000 dabbawalas and 200,000 or more deliveries a day. The two agree closely. The boxes are collected in the late morning, carried mainly by bicycle and by train, and returned empty in the afternoon, according to Wikipedia.

How a box is marked

Wikipedia describes the coding in four parts. Collection-point abbreviations identify where the box was picked up. A colour marks the station where it starts. A number marks the destination station. Further markings identify the handler, the building and the floor. The idea is that each person in the chain reads only the part that concerns them, so a box can change hands several times between kitchen and desk without anyone needing to know the whole route.

CNN, reporting from Mumbai in 2004, described the same idea: each box is colour-coded and marked with simple acronyms, such as HO for hospital, according to its final destination, and carries a second code so it returns to where it started. We read it as a relay: each hand needs one mark, not the whole address. That is our reading, not a statement from any source.

Where it started

Both sources say the service dates to 1890. They tell it differently. Wikipedia says Mahadeo Havaji Bachche started a lunch delivery service in Bombay that year with about 100 men. The dabbawalas’ site says that about 125 years ago a Parsi banker wanted home-cooked lunch at his office and gave the job to the first dabbawala, and that Bachche later started the service in its present team-based format, beginning with 100 dabbawalas. So one source credits Bachche with the start and the other credits him with the format. We show both and settle neither.

Dates in order

1890: the service begins, according to both Wikipedia and the dabbawalas’ own site.
1962: headquarters of the Mumbai Tiffin Box Suppliers Association moves to Dadar, according to Wikipedia.
1968: the association’s commercial arm is registered, according to Wikipedia.
1998: a quality study reported by the dabbawalas’ site as a Forbes Global study; Wikipedia says the later “one mistake in 8 million” figure was extrapolated from a 1998 interview.
2005: the Indian Institute of Management, Ahmedabad features the dabbawalas in a logistics case study, according to Wikipedia and the dabbawalas’ site.
2010: Harvard Business School adds the case study “The Dabbawala System: On-Time Delivery, Every Time”, according to Wikipedia. The Edge Malaysia also reports the case.

The Six Sigma claim

This is where the sources part company. The dabbawalas’ site says a 1998 Forbes Global quality assurance study gave the operation a Six Sigma efficiency rating of 99.999999, and CNN repeated in 2004 that Forbes had awarded a six-sigma rating. Wikipedia, quoting the Forbes writer, says the widely repeated figure of one mistake in 8 million deliveries is his own extrapolation from a 1998 interview, not a rigorous study, and that Forbes never certified the dabbawalas as a Six Sigma organisation.

Side by side

The producer’s own page states the rating as fact. The encyclopaedia says it was never certified. Our reading: the system plainly works at a very large scale, and the sources agree on that, but the specific statistical claim should be treated as unproven. That is our inference, and neither source says it in those words.

What kind of sources these are

Wikipedia; the dabbawalas’ own organisational website, which is a producer’s page and promotes the service; and CNN’s 2004 report from Mumbai, which is the independent source for the coding and for how far the Six Sigma claim spread. The Edge Malaysia is the source for the Harvard case study.

Questions a reader would ask

Do the dabbawalas wear anything distinctive? The dabbawalas’ site says they wear white outfits and traditional Gandhi caps.

Does the pay or price matter here? We have left both out. Figures change, and neither source gives a current one we can stand behind.

What we left out

The monthly earnings figure on the Wikipedia page, the name of the person interviewed in 1998, any charity or food-donation details, and any film or media appearances. We also left out advice on how to watch the round, because no source described it.

Quick answers

When did the Mumbai dabbawala service start? Both Wikipedia and the dabbawalas’ own site say 1890. Wikipedia credits Mahadeo Havaji Bachche with starting it with about 100 men.

How many lunch boxes do dabbawalas deliver? Wikipedia estimates 175,000 to 200,000 boxes a day by 4,500 to 5,000 dabbawalas. The dabbawalas’ site gives 200,000 or more.

Were the dabbawalas certified Six Sigma by Forbes? Wikipedia says no. It says Forbes never certified them and that the one-in-8-million figure is an extrapolation. The dabbawalas’ site claims a 1998 Six Sigma rating.
