A good example of "designing in prod" from the last week:
we shipped a very rough v1 of invoicing to prod in a few days. Initially we were not super happy with it, but the point was to get the working code to prod, even if it needed some polish.
We got some feedback, tried it ourselves, and spent the next few days polishing the UI to something we were all much happier with.
