Like a few of our classmates mentioned, design reviews are typically more relaxed. I had the opportunity to sit in on a few design reviews during my time as an intern. In most cases the suggested changes had already been given to the managers beforehand and the requested changes made. This is not to say that there were no additional changes, but that a majority of critical changes had already been made. The review is then more of a formality and a second chance for any previously missed changes. These are typically prepared a week or two in advance with all documentation and Change Order form ready to route. Once approved these are routed through documentation control and various departments for sign off.
