Fast Company has a good one how to support serendipity and produce an innovation:

"Something magical happens when you bring together a group of people from different disciplines with a common purpose. It's a middle zone, the breakthrough zone. The idea is to start a team on a problem--a hard problem, to keep people motivated. When there's an obstacle, instead of dodging it, bring in another point of view: an electrical engineer, a user interface expert, a sociologist, whatever spin on the market is needed. Give people new eyeglasses to cross-pollinate ideas."
