Great Ideas and Those Who have Them

October 20th, 2014 · No Comments

by Dwayne Phillips A great idea is merely a requirement; it is not a design. The thinker of the great idea is important, but so is everyone else involved in the endeavor. Allow me to start with a blunt statement: Steve Jobs did not design the iMac, the iPod, the iPhone, and nothing else that […]
