"It used to be that proprietary technologies, priced at a premium, provided the main source of competitive advantage. But as the information industry continues to mature and the companies in it become more fully developed, I believe that product differentiation, while still important, will become much harder to achieve. It will give way to process innovation as the fundamental source of competitive advantage."

Michael Dell, CEO of Dell Corp.
