The result is big time dividend as mentioned in P&G's New Innovation Model in March 2006, by Larry Huston and Nabil Sakkab on HBS Working Knowledge.
More than 35 percent of our new products in market have elements that originated from outside P&G, up from about 15 percent in 2000. And 45 percent of the initiatives in our product development portfolio have key elements that were discovered externally. Through connect and develop—along with improvements in other aspects of innovation related to product cost, design, and marketing—our R&D productivity has increased by nearly 60 percent. Our innovation success rate has more than doubled, while the cost of innovation has fallen. R&D investment as a percentage of sales is down from 4.8 percent in 2000 to 3.4 percent today. And, in the last two years, we've launched more than 100 new products for which some aspect of execution came from outside the company. Five years after the company's stock collapse in 2000, we have doubled our share price and have a portfolio of twenty-two billion-dollar brands.
That's pretty amazing and should be a call for action for any executive out there. Co-creation works in a big way!
