The Secret of Wal-Marts Success
What accounts for Wal-Marts remarkable success? Most explanations focus on a few familiar and highly visible factors: the genius of founder Sam Walton, who inspires his employees and has molded a culture of service excellence; the “greeters” who welcome customers at the door; the motivational power of allowing employees to own part of the business; the strategy of “everyday low prices” that offers the customer a better deal and saves on merchandising and advertising costs. Economists also point to Wal-Marts big stores, which offer economies of scale and a wider choice of merchandise.
But such explanations only redefine the question. Why is Wal-Mart able to justify building bigger stores? Why does Wal-Mart alone have a cost structure low enough to accommodate everyday low prices and greeters? And what has enabled the company to continue to grow far beyond the direct reach of Sam Waltons magnetic personality? The real secret of Wal-Marts success lies deeper, in a set of strategic business decisions that transformed the company into a capabilities-based competitor.
The starting point was a relentless focus on satisfying customer needs. Wal-Marts goals were simple to define but hard to execute: to provide customers access to quality goods, to make these goods available when and where customers want them, to develop a cost structure that enables competitive pricing, and to build and maintain a reputation for absolute trustworthiness. The key to achieving these goals was to make the way the company replenished inventory the centerpiece of its competitive strategy.
This strategic vision reached its fullest expression in a largely invisible logistics technique known as “cross-docking.” In this system, goods are continuously delivered to Wal-Marts warehouses, where they are selected, repacked, and then dispatched to stores, often without ever sitting in inventory. Instead of spending valuable time in the warehouse, goods just cross from one loading dock to another in 48 hours or less.
Cross-docking enables Wal-Mart to achieve the economies that come with purchasing full truckloads of goods while avoiding the usual inventory and handling costs. Wal-Mart runs a full 85% of its goods through its warehouse system — as opposed to only 50% for Kmart. This reduces Wal-Marts costs of sales by 2% to 3% compared with the industry average. That cost difference makes possible the everyday low prices.
But thats not all. Low prices in turn mean that Wal-Mart can save even more by eliminating the expense of frequent promotions. Stable prices also make sales more predictable, thus reducing stockouts and excess inventory. Finally, everyday low prices bring in the customers, which translates into higher sales per retail square foot. These advantages in basic economics make the greeters and the profit sharing easy to afford.
With such obvious benefits, why dont all retailers use cross-docking? The reason: it is extremely difficult to manage. To make cross-docking work, Wal-Mart has had to make strategic investments in a variety of interlocking support systems far beyond what could be justified by conventional ROI criteria.
For example, cross-docking requires continuous contact among Wal-Marts distribution centers, suppliers, and every point of sale in every store to ensure that orders can flow in and be consolidated and executed within a matter of hours. So Wal-Mart operates a private satellite-communication system that daily sends point-of-sale data directly to WalMarts 4,000 vendors.
Another key component of Wal-Marts logistics infrastructure is the companys fast and responsive transportation system. The companys 19 distribution centers are serviced by nearly 2,000 company-owned trucks. This dedicated truck fleet permits Wal-Mart to ship goods from warehouse to store in less than 48 hours and to replenish its store shelves twice a week on average. By contrast, the industry norm is once every two weeks.
To gain the full benefits of cross-docking, WalMart has also had to make fundamental changes in its approach to managerial control. Traditionally in the retail industry, decisions about merchandising, pricing, and promotions have been highly centralized and made at the corporate level. Cross-docking, however, turns this command-and-control logic on its head. Instead of the retailer pushing products into the system, customers “pull” products when and where they need them. This approach places a premium on frequent, informal cooperation among stores, distribution centers, and suppliers — with far less centralized control.
The job of senior management at Wal-Mart, then, is not to tell individual store managers what to do but to create an environment where they can learn from the market — and from each other. The companys information systems,
