Michael Dell founded Dell Computer Corporation in 1984. In the early 1990s, Dell began expanding internationally and offering notebook computers. However, in 1993 Dell reported profits that were half of projections and its stock price plunged after recalling faulty notebooks. Dell's strategy focused on building customized computers to order using a direct sales model and partnering closely with suppliers to improve quality and efficiency. This allowed Dell to gain competitive advantages through lower costs, strong customer service, and the ability to quickly adopt new technologies.
