The Edisonian approach to innovation is characterized by trial and error discovery rather than a systematic theoretical approach. This may be a convenient term, but it is an inaccurate and misleading description of the method of invention actually used by Thomas Edison. An often quoted example of the Edisonian approach is the successful but protracted process he is said to have used to invent a practical incandescent light bulb. Trial and error alone cannot account for Edison's success with electric lighting when so many others failed (Friedel and Israel (1987) list 23 others) or his remarkable record of almost 1100 patents (see the list of Edison patents).
The historical record indicates that Edison's approach was much more complex, that he made use of available theories and resorted to trial and error only when no adequate theory existed.

Famous quotes containing the word approach:
“The white man regards the universe as a gigantic machine hurtling through time and space to its final destruction: individuals in it are but tiny organisms with private lives that lead to private deaths: personal power, success and fame are the absolute measures of values, the things to live for. This outlook on life divides the universe into a host of individual little entities which cannot help being in constant conflict thereby hastening the approach of the hour of their final destruction.”
—Policy statement, 1944, of the Youth League of the African National Congress. pt. 2, ch. 4, Fatima Meer, Higher than Hope (1988)
