Michael Dell built Dell Inc. on process innovation by assembling and selling personal computers at low cost rather than product innovation. While Dell relied on suppliers for components, it was forced to innovate as competitors introduced new models. Dell has since driven innovation in areas like e-commerce, mobile computing, cloud computing and virtualization. Customer-driven innovation is at Dell's forefront, where it gathers requirements and partners with suppliers to deliver solutions meeting customer needs. Innovation is again key to Dell's survival strategy as the PC market declines.
