Innovation Economics as driven by Disruptive Innovation
Clearly there are (at least) 3 main areas of consideration re the signfiicant impact of Disruptive Innovation (Schrumpeter/Christensen-style).
One will be from the perspective of the start-up. If the intention of the start-up is for maximum success (particularly in the long-term) independent of interference (or buy out) from/by the incumbents, then evaluating the business proposition from the perspective of disruptive innovation should serve to minimize the profile projected on the incumbent radar.
The second primary perspective (not necessarily in order of priority) to be considered is that of the incumbent. If you're king, it's always good to have a read on the pulse of your environment rather than only the environment in which you operate directly. As a (modern) sage once remarked (in the spirit of business as the Art of War) - "Keep your friend close and your enemies closer", and appropriate attention to the stakeholders of your industry from the perspective of disruptive innovation will do just that.
It is the 3rd primary perspective of disruptive innovation for which this forum has been established - namely, the effect of support for disruptive innovation on the society at large. Schrumpeter (as have an ever-inreasing number of modern economists) ascribed the bulk of economic growth (upwards of 80% is becoming the concensus) as having come about as a result of innovation, with disruptive innovation identified as responsible for all of the advance from one quantum level to the next within a given industry.
In any event, if you're interested in the framework under which modern society has finally come to terms with the need to pro-actively engage in thoughts and actions which unambiguously result in increases in the means whereby we become and remain the economic best we can be, Simona Lovin's article (have a look at Simona Lovin's post, at http://www.vangent.com/Outlooks/blog/2011/05/02/the-methodical-pursuit-of-disruptive-innovations-part-1/ ) would be a very nice place to begin.
Thanks for visiting - I look forward to an increasingly interesting and productive discussion as we collect and support those with similar interest in this Group.
