While working at General Dynamics Electric Boat, the culture for the design review meeting was rather relaxed. The design review meeting is schedule at least 4 weeks in advanced so there is ample time to review the documents and discuss changes before the actual meeting. The general attitude is that it was a formality where everyone gets in one room to review the changes and sign off on it. All the work is done prior to the actual meeting. Before the actual meeting when you send out the meeting invite, you send out the document and ask for comments within one week. People will not give you comments within one week but this is usually the time you start calling people and tell them to get their comments in within 24 hrs or you contact their management. They will give you comments after this and you will resolve them and facilitate conversation between different people.
