Ideas are developed everyday and have been since time immemorial. Some ideas died a premature death or failed to gain traction. Others however, have changed how we view and do things. Two such ideas are, 1) Michael Porter's Five (5) Forces and; 2) Clayton Christensen's Disruptive Innovation Theory.
Which of these two ideas, in your view, had the biggest impact on the world you live and work in? Please share with us, how the idea changed your world.
