Dell was founded in 1984 by Michael Dell, the longest-tenured executive to lead a company in the computer industry. The company is based on a simple concept: by selling computer systems directly to customers, Dell could best understand their needs and efficiently provide the most effective computing solutions to meet those needs. This direct business model eliminates retailers that add unnecessary time and cost, or can diminish Dell's understanding of customer expectations. The direct model allows the company to build every system to order and offer customers powerful, richly-configured systems at competitive prices. Dell also introduces the latest relevant technology much more quickly than companies with slow-moving, indirect distribution channels, turning over inventory in just under five days on average.
