I've been offering this week several examples of Public-Private Partnerships (P3s) that aren't about funding and building large infrastructure, but instead about working together to achieve important public policy goals. 

This article, targeted around the issue of P3s to improve the transportation grid, offers 10 lessons learned. While they are talking specifically about transportation issues, I think the 10 lessons are applicable to nearly any topic where you might be thinking about taking a 'P3 approach', so is well worth reading. 

Let me know if you have any examples of a P3 supporting government policy that you are involved in.
