How to identify your enemies before they destroy you

We've all heard the stories about corporate giants who ignored disruptive innovations and paid a steep price: Think what the personal computer did to Digital or Japanese economy cars did to the Big Three automakers. Big companies now spend a lot of time and money trying to make sure they don't get blindsided by their smaller, leaner counterparts. But it's not easy to distinguish genuine threats from also-rans as they emerge. Most of the nascent technologies that typically bombard executives will not amount to competitive threats and deserve to be ignored. As a result, disruptions are usually not taken seriously until they become obvious--when it's often too late. A disruptive innovation is a technology, product, or process that creeps up from below an existing business and threatens to displace it. Usually, the disrupter offers lower performance and less functionality at a much lower price. The product or process is good enough to meet some customers' needs; others welcome the disruption's simplicity. Gradually, it improves to the point where it displaces the incumbent. But, the authors argue, disruption isn't inevitable. They have developed a tool that can help companies detect potential disruptive innovations while management still has time to respond effectively. The tool's decision-making methodology harnesses the organization's collective wisdom to determine how likely it is that a particular innovation will seriously damage an incumbent's business. The methodology has two components: an analytical instrument and an organizational process. There's nothing magical about it--but it gets managers to think systematically about identifying and addressing threats to the core business. And the tool's rigorous approach can spell the difference between flailing around and acting effectively in the face of a serious competitive threat.
