"No other technology company listens to customers, collaborates with partners, adds its own significant layer of innovation and delivers relevant technology more efficiently and effectively than Dell." These words from Michael Dell point out more than anything else how the Dell company managed to advance to the worldwide number one in the computer industry. From a little company founded by an undergraduate student at the University of Texas, Dell Inc., headquartered in Round Rock, Texas, has developed into a huge corporation with more than 55,200 employees today and an annual turnover of nearly $50 billion. This report aims to analyse how the Dell company performs in the competitive environment of the computer industry, which factors are essential for success and how Dell successfully takes advantage of its business structure. Furthermore, an internal analysis will be conducted and the resulting strengths and weaknesses will be presented. The future developments of the computer industry in general and of the Dell company in particular, will be examined at the end of this paper.
