Clayton Christensen's "Innovator's Dilemma" is probably the most widely publicized description of "Disruptive Innovation" and the reason for the phrase entering the laymen's vocabulary.  His book was interesting for sure to read - and also outlined why for a large company unwilling to abandon existing businesses, it becomes difficult to pursue "disruptive innovation" as opposed to so-called line-extensions, or "sustainable innovation."  (see first link)

Looking further back though, the late Peter Drucker had written several books on what I would describe as actions corporate management must actively take to grow -- chief among it being innovation (he had written over a good part of the 20th century, so many books to choose from!  I've yet to be disappointed by any of his books). 

Of course, the late Joseph Schumpeter and his concept of creative destruction (of which innovation is a central part) in free-market capitalism is just as important to learn from (I've not read any of his books, but his books are referenced frequently, particularly in Thomas Sewell's book "Basic Economics").

Thank you Kaoru for the reply. Believe I couldn't clearly put my question. I was reading a research article (Kanter, 1988) in which she explained the tasks of innovation. I was wondering if tasks of DI have been researched on the same lines before, though i couldn't find anything on the internet during initial search. I hope that clarifies my question.

Sorry about the misunderstanding.  Can you specify the reference?  I'm not sure I'm finding the right reference.

IMHO it is nor correct to use term tasks regarding disruptive innovation. Disruptive is a nature of them. They change completely current market environment. 

The first thing is that there is a problem with the definition. Clayton Christensen explains us recently that Uber was  not a disruptive innovation. But obviously, it is one ! Because you see the taxi drivers in the street again Uber. In social science, it is difficult to  use a definition against common sense.

If you agree with the definition of the nature of innovation as a new social paradigm with a sustainable increase of efficiency, the question of disruption is only a question of efficiency change.

If you get an increase over 5 times, you'l get a disruptive innovation that means that everybody will have to use the new paradigm (product or organization ....).

The question is now the valuation of innovation.

For Uber, you have the price of the fare ... that is half the price !

And you have the service : always and immediately available, no waiting line, friendliness, no need to make reservation etc. >> that is "liberty" and have no price !

For valuation, if you only take into account the waiting time, you often double or triple the cost of the taxi. That means that the real value for the user is divided by 4 to 6. And the feeling of liberty is so huge that it overwhelms all other analysis by the user.

Thank You Patrice and Vitalii for your valuable comments. Considering Disruptive Innovation as a subset of Innovation with radical characteristics on Market dimension, how would one can define the phenomenon of Disruption at individual level? Or to say Disruptive output of an individual?

Dear Ales, first of all thank you for taking out time to write the comment. Are you suggesting that even innovative activities cannot be explained at individual level? Because such constructs do exist in the extant literature with certain level of validity supported by empirical tests. And based on extensive historical data analysis, there are also various research studies which explains the characteristics of Disruptive Innovation and add certain level of predictability in the theory. I would be grateful, if you can please refer to some evidence based article/s where unpredictability of Disruptive Innovation has been proven, empirically. Thanks again for providing an alternate point of view.

Cheers.
