Examples of economic success stories attributable to a system's strength abound. Last year's front page story in the Wall Street Journal, describing Wal-Mart's triumph over K-Mart, was a study in infrastructure superiority. Wal-Mart's investment in a computer system that linked its cash registers to its headquarters gave Wal-Mart a powerful, winning edge over its competition. A sophisticated distribution, inventory, and scanner system meant not only enhanced control and lower costs, but also well-stocked shelves and no price-check delays at the register. Other business sectors have similar success stories.
