| Sumario: | A debate on the worth of information technology (IT) has been raised by Nicholas Carr, a junior editor at the Harvard Business Review. Carr's argument that “IT doesn't matter” is simple, powerful, and subtle. He does not deny that IT has the potential to transform entire societies and economies, but he stresses that computer hardware and software has joined history's other revolutionary technologies by becoming an infrastructure rather than a differentiator. On the grounds that IT can no longer be a source of strategic advantage, Carr advises chief information officers to spend less on their data-centers, choose cheaper commodity equipment when possible, follow their rivals rather than trying to outdo them with fancy new systems, and focus more on IT's vulnerabilities than its opportunities.
