  30. 30. Simplexity Lehrstuhl für Virtuelle Produktentwicklung Symplicity means to reach the largest effect with the smallest effort….. - Albert Einstein There is no justification for complexity if things could be easy. - Leonardo Da Vinci Ora Ito, Designer © 14.3.2011 Eigner VPE Folie: 31
  31. 31. Jeffrey Kluger Symplexity Lehrstuhl für Virtuelle Produktentwicklung Simplexity: Why Simple Things Become Complex (And How Complex Things Can Be Made Simple) By Jeffrey Kluger WHY are the instruction manuals for cell phones incomprehensible? WHY is a truck driver’s job as hard as a CEO’s? HOW can 10 percent of every medical dollar cure 90 percent of the world’s disease? WHY do bad teams win so many games? Complexity, as any scientist will tell you, is a slippery idea. Things that seem complicated can be astoundingly simple; things that seem simple can be dizzyingly complex. A houseplant may be more intricate than a manufacturing plant. A colony of garden ants may be more complicated than a community of people. A sentence may be richer than a book, a couplet more complicated than a song.© 14.3.2011 Eigner VPE Folie: 32
