Product reviews that happen in the room
If the first honest comment appears in a chat thread after the meeting, the review already failed.
A product review that only happens in comments is a delay with extra steps. We still send the deck the night before. The meeting is for the disagreements that do not survive a thread.
Nina Holm runs reviews standing up, with the build on a large screen and the research notes on paper. The first question is always the same: who is this for this week, not this quarter.
If a decision cannot be written in one sentence on the wall, we do not leave the room. That sounds slow. It is faster than rediscovering the same argument in four tools.
