In addition to giving ample time for members of the project team to review documents before their approval, I think that it would be beneficial to have frequent short meetings in between official design review document approval meetings. I think that this can be an efficient way to ensure that all members of the project team are continuously on the same page, and can address issues or changes as they come up so that when an approval meeting comes around there should be no surprises because ideally all of the kinks would be worked out by then. This would require some scheduling, but the meetings don’t necessarily have to be in person. The project manager can send out an email and schedule a short 10 minute conference call for a time all key members are available where they can voice their concerns if any. Constant communication is key.
