The World is Flat - Friedman Thomas (читать книги без сокращений .TXT) 📗
David Glass, the company's CEO from 1988 to 2000, oversaw many of the innovations that made Wal-Mart the biggest and most profitable retailer on the planet. Fortune magazine once dubbed him “the most underrated CEO ever” for the quiet way he built on Sam Walton's vision. David Glass is to supply-chaining what Bill Gates is to word processing. When Wal-Mart was just getting started in northern Arkansas in the 1960s, explained Glass, it wanted to be a discounter. But in those days, every five-and-dime got its goods from the same wholesalers, so there was no way to get an edge on your competitors. The only way Wal-Mart could see to get an edge, he said, was for it to buy its goods in volume directly from the manufacturers. But it wasn't efficient for manufacturers to ship to multiple Wal-Mart stores spread all over, so Wal-Mart set up a distribution center to which all the manufacturers could ship their merchandise, and then Wal-Mart got its own trucks to distribute these goods itself to its stores. The math worked like this: It cost roughly 3 percent more on average for Wal-Mart to maintain its own distribution center. But it turned out, said Glass, that cutting out the wholesalers and buying direct from the manufacturers saved on average 5 percent, so that allowed Wal-Mart to cut costs on average 2 percent and then make it up on volume.
Once it established that basic method of buying directly from manufacturers to get the deepest discounts possible, Wal-Mart focused relentlessly on three things. The first was working with the manufacturers to get them to cut their costs as much as possible. The second was working on its supply chain from those manufacturers, wherever they were in the world, to Wal-Mart's distribution centers, to make it as low-cost and fric-tionless as possible. The third was constantly improving Wal-Mart's information systems, so it knew exactly what its customers were buying and could feed that information to all the manufacturers, so the shelves would always be stocked with the right items at the right time.
Wal-Mart quickly realized that if it could save money by buying directly from the manufacturers, by constantly innovating to cut the cost of running its supply chain, and by keeping its inventories low by learning more about its customers, it could beat its competitors on price every time. Sitting in Bentonville, Arkansas, it didn't have much choice.
“The reason we built all our own logistics and systems is because we are in the middle of nowhere,” said Jay Allen, Wal-Mart's senior vice president of corporate affairs. “It really was a small town. If you wanted to go to a third party for logistics, it was impossible. It was pure survival. Now with all the attention we are getting there is an assumption that our low prices derive from our size or because we're getting stuff from China or being able to dictate to suppliers. The fact is the low prices are derived from efficiencies Wal-Mart has invested in-the system and the culture. It is a very low-cost culture.” Added Glass, “I wish that I could say we were brilliant and visionary, [but] it was all born out of necessity.”
The more that supply chain grew, the more Walton and Glass understood that scale and efficiency were the keys to their whole business. Put simply, the more scale and scope their supply chain had, the more things they sold for less to more customers, the more leverage they had with suppliers to drive prices down even more, the more they sold to more customers, the more scale and scope their supply chain had, the more profit they reaped for their shareholders...
Sam Walton was the father of that culture, but necessity was its mother, and its offspring has turned out to be a lean, mean supply-chain machine. In 2004, Wal-Mart purchased roughly $260 billion worth of merchandise and ran it through a supply chain consisting of 108 distribution centers around the United States, serving the some 3,000 Wal-Mart stores in America.
In the early years, “we were small-we were 4 or 5 percent of Sears and Kmart,” said Glass. “If you are that small, you are vulnerable, so what we wanted to do more than anything else was grow market share. We had to undersell others. If I could reduce from 3 percent to 2 percent the cost of running my distribution centers, I could reduce retail prices and grow my market share and then not be vulnerable to anyone. So any efficiency we generated we passed on to the consumer.”
For instance, after the manufacturers dropped off their goods at the Wal-Mart distribution center, Wal-Mart needed to deliver those goods in small bunches to each of its stores. It meant that Wal-Mart had trucks going all over America. Walton quickly realized if he connected his drivers by radios and satellites, after they dropped off at a certain Wal-Mart store, they could go a few miles down the road and pick up goods from a manufacturer so they wouldn't come back empty and so Wal-Mart could save the delivery charges from that manufacturer. A few pennies here, a few pennies there, and the result is more volume, scope, and scale.
In improving its supply chain, Wal-Mart leaves no link untouched. While I was touring the Wal-Mart distribution center in Bentonville, I noticed that some boxes were too big to go on the conveyor belts and were being moved around on pallets by Wal-Mart employees driving special minilift trucks with headphones on. A computer tracks how many pallets each employee is plucking every hour to put onto trucks for different stores, and a computerized voice tells each of them whether he is ahead of schedule or behind schedule. “You can choose whether you want your computer voice to be a man or a woman, and you can choose English or Spanish,” explained Rollin Ford, Wal-Mart's executive vice president, who oversees the supply chain and was giving me my tour.
A few years ago, these pallet drivers would get written instructions for where to pluck a certain pallet and what truck to take it to, but Wal-Mart discovered that by giving them headphones with a soothing computer voice to instruct them, drivers could use both hands and not have to carry pieces of paper. And by having the voice constantly reminding them whether they were behind or ahead of expectations, “we got a boost in productivity,” said Ford. It is a million tiny operational innovations like this that differentiate Wal-Mart's supply chain.
But the real breakthrough, said Glass, was when Wal-Mart realized that while it had to be a tough bargainer with its manufacturers on price, at the same time the two had to collaborate to create value for each other horizontally if Wal-Mart was going to keep driving down costs. Wal-Mart was one of the first companies to introduce computers to track store sales and inventory and was the first to develop a computerized network in order to share this information with suppliers. Wal-Mart's theory was that the more information everyone had about what customers were pulling off the shelves, the more efficient Wal-Mart's buying would be, the quicker its suppliers could adapt to changing market demand.
In 1983, Wal-Mart invested in point-of-sale terminals, which simultaneously rang up sales and tracked inventory deductions for rapid resup-ply. Four years later, it installed a large-scale satellite system linking all of the stores to company headquarters, giving Wal-Mart's central computer system real-time inventory data and paving the way for a supply chain greased by information and humming down to the last atom of efficiency. A major supplier can now tap into Wal-Mart's Retail Link private extranet system to see exactly how its products are selling and when it might need to up its production.
“Opening its sales and inventory databases to suppliers is what made Wal-Mart the powerhouse it is today, says Rena Granofsky, a senior partner at J. C. Williams Group Ltd., a Toronto-based retail consulting firm,” in the 2002 Computerworld article on Wal-Mart. “While its competition guarded sales information, Wal-Mart approached its suppliers as if they were partners, not adversaries, says Granofsky. By implementing a collaborative planning, forecasting, and replenishment (CPFR) program, Wal-Mart began a just-in-time inventory program that reduced carrying costs for both the retailer and its suppliers. 'There's a lot less excess inventory in the supply chain because of it/ Granofsky says.” Thanks to the efficiency of its supply chain alone, Wal-Mart's cost of goods is estimated to be 5 to 10 percent less than that of most of its competitors.
