I agree with you that design meetings facilitate communication between the parties involved such as management, design team, and the customer. Although I don’t have experience with design review meetings, I understand, from research, that they are critical for the members to review their progress and discuss a way forward. When evaluating a design against the requirements, a number of means such as physical tests, walk-through examinations, and engineering simulations may be used. Although the design meetings happen at the end of each stage of the product development, their timing is important. It is imperative that these meetings are held when every member of the team and participants are present. The team members ought to be notified in advance of the intention to hold the design review meetings. In design review meetings, the contribution of every member is important, and thus no member should be left out.
