Thomas Friedman - The World is Flat

Now Wal-Mart, in its latest supply-chain innovation, has introduced RFID-radio frequency identification microchips, attached to each pallet and merchandise box that comes into Wal-Mart, to replace bar codes, which have to be scanned individually and can get ripped or soiled. In June 2003, Wal-Mart informed its top one hundred suppliers that by January 1, 2005, all pallets and boxes that they ship to Wal-Mart distribution centers have to come equipped with RFID tags. (According to the RFID Journal, “RFID is a generic term for technologies that use radio waves to automatically identify people or objects. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip that is attached to an antenna-the chip and the antenna together are called an RFID transponder or an RFID tag. The antenna enables the chip to transmit the identification information to a reader. The reader converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can make use of it.”) RFID will allow Wal-Mart to track any pallet or box at each stage in its supply chain and know exactly what product from which manufacturer is inside, with what expiration date. If a grocery item has to be stored at a certain temperature, the RFID tag will tell Wal-Mart when the temperature is too high or too low. Because each of these tags costs around 200, Wal-Mart is reserving them now for big boxes and pallets, not individual items. But this is clearly the wave of the future.

“When you have RFID,” said Rollin Ford, the Wal-Mart logistics vice president, “you have more insights.” You can tell even faster which stores sell more of which shampoo on Fridays and which ones on Sundays, and whether Hispanics prefer to shop more on Saturday nights rather than Mondays in the stores in their neighborhoods. “When all this information is fed into our demand models, we can become more efficient on when we produce [a product] and when we ship it and then put it on the trucks in exactly the right place inside the trucks so it can flow more efficiently,” added Ford. “We used to have to count each piece, and scanning it at [the receiving end] was a bottleneck. Now [with RFID], we just scan the whole pallet under a bubble, and it says you have all thirty items you ordered and each box tells you, 'This is what I am and this is how I am feeling, this is what color I am, and am I in good shape'-so it makes receiving hugely easier.” Procter & Gamble spokesperson Jeannie Tharrington talked to Salon.com (September 20, 2004) about Wal-Mart's move to RFID: “We see this as beneficial to the entire supply chain. Right now our out-of-stock levels are higher than we'd like and certainly higher than the consumer would like, and we think this technology can help us to keep the products on the shelf more often.” RFID will also allow for quicker remixing of the supply chain in response to events.

During hurricanes, Wal-Mart officials told me, Wal-Mart knows that people eat more things like Pop-Tarts-easy-to-store, nonperishable items-and that their stores also sell a lot of kids' games that don't require electricity and can substitute for TV. It also knows that when hurricanes are coming, people tend to drink more beer. So the minute Wal-Mart's meteorologists tell headquarters a hurricane is bearing down on Florida, its supply chain automatically adjusts to a hurricane mix in the Florida stores-more beer early, more Pop-Tarts later.

Wal-Mart is constantly looking for new ways to collaborate with its customers. Lately, it has gone into banking. It found that in areas with large Hispanic populations, many people had no affiliation with a bank and were getting ripped off by check-cashing outlets. So Wal-Mart offered them payroll check cashing, money orders, money transfers, and even bill payment services for standard items like electricity bills-all for very small fees. Wal-Mart had an internal capability to do that for its own employees and simply turned it into an external business.

Unfortunately for Wal-Mart, the same factors that drove its instinct for constant innovation-its isolation from the world, its need to dig inside itself, and its need to connect remote locations to a global supply chain— also got it in trouble. It is hard to exaggerate how isolated Bentonville, Arkansas, is from the currents of global debate on labor and human rights, and it is easy to see how this insular company, obsessed with lowering prices, could have gone over the edge in some of its practices.

Sam Walton bred not only a kind of ruthless quest for efficiency in improving Wal-Mart's supply chain but also a degree of ruthlessness period. I am talking about everything from Wal-Mart's recently exposed practice of locking overnight workers into its stores, to its allowing Wal-Mart's maintenance contractors to use illegal immigrants as janitors, to its role as defendant in the largest civil-rights class-action lawsuit in history, to its refusal to stock certain magazines-like Playboy-on its shelves, even in small towns where Wal-Mart is the only major store. This is all aside from the fact that some of Wal-Mart's biggest competitors complain that they have had to cut health-care benefits and create a lower wage tier to compete with Wal-Mart, which pays less and covers less than most big companies (more on this later). One can only hope that all the bad publicity Wal-Mart has received in the last few years will force it to understand that there is a fine line between a hyperefficient global supply chain that is helping people save money and improve their lives and one that has pursued cost cutting and profit margins to such a degree that whatever social benefits it is offering with one hand, it is taking away with the other.

Wal-Mart is the China of companies. It has so much leverage that it can grind down any supplier to the last halfpenny. And it is not at all hesitant about using its ability to play its foreign and domestic suppliers off against each other.

Some suppliers have found ways to flourish under the pressure and become better at what they do. If all of Wal-Mart's suppliers were being squeezed dry by Wal-Mart, Wal-Mart would have no suppliers. So obviously many of them are thriving as Wal-Mart's partners. But some no doubt have translated Wal-Mart's incessant price pressure into lower wages and benefits for their employees or watched as their business moved to China, whence Wal-Mart's supply chain pulled in $18 billion worth of goods in 2004 from five thousand Chinese suppliers. “If Wal-Mart were an individual economy, it would rank as China's eighth-biggest trading partner, ahead of Russia, Australia and Canada,” Xu Jun, the spokesman for Wal-Mart China, told the China Business Weekly (November 29, 2004).

The successor generation to Sam Walton's leadership seems to recognize that it has both an image and a reality to fix. How far Wal-Mart will adjust remains to be seen. But when I asked Wal-Mart's CEO, H. Lee Scott Jr., directly about all these issues, he did not duck. In fact, he wanted to talk about it. “What I think I have to do is institutionalize this sense of obligation to society to the same extent that we have institutionalized the commitment to the customer,” said Scott. “The world has changed and we have missed that. We believed that good intentions and good stores and good prices would cause people to forgive what we are not as good at, and we were wrong.” In certain areas, he added, “we are not as good as we should be. We just have to get better.”

One trend that Wal-Mart insists it is not responsible for is the off-shoring of manufacturing. “We are much better off if we can buy merchandise made in the United States,” said Glass. “I spent two years going around this country trying to talk people into manufacturing here. We would pay more to buy it here because the manufacturing facilities in those towns [would create jobs for] all those people who shopped in our stores. Sanyo had a plant here [in Arkansas] making television sets for Sears, and Sears cut them off, so they decided they were closing the plant and going to move part to Mexico and part to Asia. Our governor asked if we would help. We decided we would buy television sets from Sanyo [if they would keep the plant in Arkansas], and they didn't want to do it. They wanted to move it, and [the governor] even talked to the [Japanese owning] family to try to persuade them to stay. Between his efforts and ours, we persuaded them to do it. They are now the world's largest producer of televisions. We just bought our fifty millionth set from them. But for the most part people in this country have just abandoned the manufacturing process. They say, 'I want to sell to you, but I don't want the responsibility for the buildings and employees [and health care]. I want to source it somewhere else.' So we were forced to source merchandise in other places in the world.” He added, “One of my concerns is that, with the manufacturing out of this country, one day we'll all be selling hamburgers to each other.”
