Thanks for pulling this together Dan. Great round-up. I’ve been following along these last few months as more and more teams have shared how they are approaching their design systems. One of the things I’m most interested in is how these systems evolve the relationship between design and engineering. There’s lots to unpack here. At it’s most basic I’m interested in how design systems can help our interface component libraries become less static, and more open. Anyway, here’s an additonal reference for you along those lines. Lots of good stuff happening at C0-op in the UK. Lead by a bunch of people who built GDS (Goverment Digital Services). https://digital.blogs.coop/2016/06/29/finding-our-way-with-a-co-op-design-system/
