Two of the sources from the Discover step were The Checklist Manifesto by Atul Gawande and An Ethic of Excellence: Building a Culture of Craftsmanship with Students by Ron Berger.

I propose a mash-up of these two sources resulting in an educator Checklist for Designing Innovation Experiences.

There are a few assumptions associated with this solution:
1) Designing innovative classroom experiences is really complicated (from Mission #3).
2) There are a few key components that result in designing successful innovation experiences (from Berger).
3) A well designed checklist can help ensure that these components are being met (from Gawande).

Check out the checklist here -  A Checklist for Designing Makerspace Experiences

NOTE: My original intent was in the context of Makerspaces, but perhaps the checklist could be iterated during the evolve portion to be more broad?  

Scalability:  Gawande describes the process of scaling his World Health Organization checklist, and I imagine that scaling this checklist would be analogous to their process.  I'd propose piloting in a few schools and validating via student growth as a function of checklist aligned projects.  Since one of the items on the checklist is a public audience for student work, perhaps schools implementing the checklist could share that work with Teachers Guild members.
