I was tasked by the European Commission to develop an 8 hour skills training on collaborative policymaking. It followed on this report to which I contributed on the "12 Principles of Collaborative Policymaking."
I don't actually know much about policymaking. Really, it's a skills training on how to collaborate better, following evidence-based practice (to the extent that there is such evidence).
Most of what I made is boring stuff like lesson plans, learning objectives, learning activities, etc. Ok actually some of it is pretty cool but probably won't interest you all that much. But...
The interesting part of this project is what I called the "Action Guide" which is a literal list of things you can concretely do to improve collaboration on a team. To generate this guide, I dug into actual laboratory experiments where they did some intervention, and showed scientifically that the intervention improved some metric important to collaboration. The science is a bit sketch, but it's the best we've got.
Due to the copyright restrictions in my contract, I can't publicly share the materials I made, since they now own them. But, they told me that it's fine to share the CONTENT of the documents, as long as it's not the exact wording.
So if you want to access these materials, I can give you a project: take the document I wrote, and rephrase it so that it doesn't violate copyright. Then we can share it with anyone you want.
Frankly, it could use some revision anyway.
