Nice article and a pretty useful way for reviewing design, thanks for sharing Pedro!
There's one point that even I understand on behalf of objectivity, I have to disagree at a certain extent: leave opinions at the door. Let's see, no matter you are the moderator, the presenter or another stakeholder invited to the session, you will always have an opinion made as a professional, sometimes expert, hired to share your opinion and bring value to the table.
I have the feeling that in the last years the design industry is dehumanizing itself in order to be taken more seriously, I'm not sure we should remove the human factor out of it.
I always love hearing about how teams share work and feedback with each other. Thanks for sharing!
