Vijay Govindrajan is a professor and chief innovation consultant at GE who conceptualized the theory of disruptive innovation. Disruptive innovation describes how new entrants can displace established incumbents by introducing simpler, more convenient products that appeal to new customer groups. Govindrajan provides examples like personal computers disrupting mainframes and cellular phones disrupting fixed-line telephony. He notes innovation is now occurring in emerging markets first before being brought to wealthy countries, like Nestle innovating Maggi noodles in India. Reverse innovation, where low-cost innovations from developing countries disrupt developed markets, is an important strategic priority for large companies to access new growth opportunities.
