At my current company, the design review meetings are overall pretty calm as we work together on establishing any potential changes based on feedback or simulation data. Sometimes the meetings involve having a conference call with the potential vendor to allow them to give feedback based on their capabilities and experience. There will be agreements and disagreements during these meetings, but overall everyone was respectful of each other’s opinions and suggestions whether it was good or not. It never really got heated with arguments being thrown around blasting people’s ideas. On the last project I was part of, there was a design meeting, sometimes with the vendor, every week discussing on things are progressing with the project. Are there any changes needed, any new issues that have shown up, etc. Before each meeting we all had a checklist of the discussion topics that had to be covered during the meeting.
