I see you wrote this article in April, I would love to hear how implementing the peer reviews worked out for your team. Would like to start that too in our team and I wonder how you handled the more practical aspects: did you pair designers (one-on-one reviews) or were you collectively reviewing the work (many-to-one)? Did you set fixed times for these reviews or only plan them as the needs arose? Did you get the knowledge sharing you expected? And how about speed? How did your team respond to something that can, if not framed and understood correctly, be seen as an "extra validation step"? As they say, alone you go fast but together you go further.
