In this video from Big Think, Jonah Lehrer, author of Imagine: How Creativity Works, shares a crowd sourcing site developed by Eli Lilly called InnoCentive designed to tap into the world market of innovators.

Not surprising that an expert from outside the company might have the missing piece since it's hard for us to see the assumptions that hold us back until someone with a different perspective challenges them.
More surprising is what Karim Lakhani from Harvard Business School found in a study on who solved the problems. "Most problems on InnoCentive are solved by experts outside of the field – chemistry problems solved by physicists. Engineering problems solved by chemists. And so on."
