Professor Clayton M. Christensen from Harvard University is a well-known intellect in the strategic management sector. He introduced the concept of disruptive innovation in order to describe the changes in the vastly developing industry. The disruptive innovation, the opposite of existing innovation, is an innovation method aimed to target the bottom line of the market with a simple yet cheap service and rapidly penetrate the market all throughout. One of the major characteristics of the disruptive innovation is that a company successful from the innovation becomes shackled in their own success and is unable to cope with further disruptive technology. The most important skill for a company is to have full understanding of what the customers actually want. There are two methods to understand the customers’ needs: to enter the market with technology ahead of customers’ expectation and with low price by comparing the customers’ expectation of technology with one in the market and the development speed of the low-end technology and to dominate the market by developing low price technology to the extent where the technology meets the customers’ expectation.
