Disruptive Technology

A disruptive technology or disruptive innovation is an innovation that improves a product or service in ways that the market does not expect, typically by being lower priced or designed for a different set of consumers.

Disruptive innovations can be broadly classified into low-end and new-market disruptive innovations. A new-market disruptive innovation is often aimed at non-consumption (i.e., consumers who would not have used the products already on the market), whereas a lower-end disruptive innovation is aimed at mainstream customers for whom price is more important than quality.

Disruptive technologies are particularly threatening to the leaders of an existing market, because they are competition coming from an unexpected direction. A disruptive technology can come to dominate an existing market by either filling a role in a new market that the older technology could not fill (as cheaper, lower capacity but smaller-sized flash memory is doing for personal data storage in the 2000s) or by successively moving up-market through performance improvements until finally displacing the market incumbents (as digital photography has largely replaced film photography).

In contrast to "disruptive innovation", a "sustaining" innovation does not have an effect on existing markets. Sustaining innovations may be either "discontinuous"[1] (i.e. "revolutionary") or "continuous" (i.e. "evolutionary"). Revolutionary innovations are not always disruptive. Although the automobile was a revolutionary innovation, it is not a disruptive innovation, because early automobiles were expensive luxury items that did not disrupt the market for horse-drawn vehicles. The market remained intact until the debut of the lower priced Ford Model T in 1908.

Christensen distinguishes between "low-end disruption" which targets customers who do not need the full performance valued by customers at the high-end of the market and "new-market disruption" which targets customers who have needs that were previously unserved by existing incumbents.

"Low-end disruption" occurs when the rate at which products improve exceeds the rate at which customers can adopt the new performance. Therefore, at some point the performance of the product overshoots the needs of certain customer segments. At this point, a disruptive technology may enter the market and provide a product which has lower performance than the incumbent but which exceeds the requirements of certain segments, thereby gaining a foothold in the market.

In low-end disruption, the disruptor is focused initially on serving the least profitable customer, who is happy with a good enough product. This type of customer is not willing to pay premium for enhancements in product functionality. Once the disruptor has gained foot hold in this customer segment, it seeks to improve its profit margin. To get higher profit margins, the disruptor needs to enter the segment where the customer is willing to pay a little more for higher quality. To ensure this quality in its product, the disruptor needs to innovate. The incumbent will not do much to retain its share in a not so profitable segment, and will move up-market and focus on its more attractive customers. After a number of such encounters, the incumbent is squeezed into smaller markets than it was previously serving. And then finally the disruptive technology meets the demands of the most profitable segment and drives the established company out of the market.

"New market disruption" occurs when a product fits a new or emerging market segment that is not being served by existing incumbents in the industry. The Linux operating system (OS) when introduced was inferior in performance to other server operating systems like Unix and Windows NT. But the Linux OS is inexpensive compared to other server operating systems. After years of improvements Linux is now installed in 87.8% of the worlds 500 fastest supercomputers.[5]
