7 Sources of Innovation

Innovations are sprouted from several sources of inspiration and the process by-which they evolve from a faint thought to an implemented action is quite diverse. Peter Drucker attempts to characterize the sources of innovation: The Unexpected, Incongruities, Process Needs, Industry and market structure, Demographics, Changes in Perception, New knowledge. I find that many innovators throughout history have a unique insight to a respective area of specialization and they are able to identify opportunities and develop them with significant vigor. I will cease the opportunity to broadcast what comes to my mind for each of Drucker's 7 sources of innovation.

Unexppected: Margarine was originally an experimental form of axil grease,
 yuck!
Incongruities: Subways, fast food does not always need to come from a deep frier.
Process needs:
Where there is a store shelf at a Walmart or an Apple store for that matter; best believe there is a factory worker at Foxconn working a 90 hr work week committed to filling it. 
Industry and market structure: The coffee market that was once dominated by Dunkin Donuts and Starbucks: McDonald's with the real-estate decided to created the McCafe to steal market share from the former coffee giants along with adding WiFi in every store. Unlike Starbucks, there is no outlets at McDonlds for costumer to use, I guess parking your computer for awhile will hinder McD's throughput.
Demographics:
Fazollies: the best Italian food chain that ever existed is huge hit in the United States and exists in most major cites and unlimited bread sticks. However, you will not find one in the North East, maybe they don't want to upset the mob?

Change in perception: Toyota's are awesome reliable cars with great fuel economy. However, kids don't want to drive their mom's beater Camry when they are picking up a girl he met at the skate park. Toyota, creates the Scion, re-branding at it's finest, and sales surge.
New knowledge:
"good artist create great artist steal..."
-Lianado Davinci, - Steve Jobs "Pirates of Silicon Valley"
