We've had a "design system" (quotes because it's mostly front end dev guidelines with a bit of direction for color palette) in place for just over a year now and have slowly been expanding it to more and more teams. We are considering making some updates and shifts but knowing this impacts more than just our own team I want to be sure we are getting feedback before we make changes.

Right now I'm considering gathering everyone who's used it substantially and doing a retrospective (Most of them are familiar with the start, stop, continue, change model) but it feels like a weird fit because it's not a project that's really "ended".

I'm curious how you all go about gathering and vetting feedback about your design systems?
