Product Description: Companies waste $500 billion worldwide on information technology. Why? Many CEOs, COOs, and CFOs don't see IT for what it is: a tool to support their firms' competitive strategy. Instead, they consider it a mysterious function that their firms must have--but that they'd rather not manage or integrate with the rest of the company. Result? Non-IT executives don't communicate corporate strategy to their IT departments--leading tech execs inadvertently to make choices that clash with the strategy. But you don't have to micromanage IT to unleash its true potential as a strategic weapon. Instead, link IT to your corporate strategy: Develop a long-term plan focusing your IT group on your company's strategic goals. Create a unifying technology platform to serve your entire organization, not just individual units. Demand that your IT department works as a business-savvy team that meets the same tough performance standards executives throughout your company must meet. The payoff? IT investments that transform your strategy into profits. The three Harvard Business Review articles in this collection: "Getting IT Right" by Charlie S. Feld and Donna B.
