I personally do not have any first hand experience with this situation. However, based on what I have learned in this class, I can imagine that if this were to happen, it could cause a variety of problems within the development process. Staying on track in product development is very important, but maintaining a high standard for the work done and ensuring every step along the path is completed to the full extent is the most essential. If the verdict of a design review meeting it to move onto the next stage of development without successful completion of the prior phase, it will inevitably cause delays. For that reason, I think that in exception of extreme situations, it should be ensured that all prior tasks have been successfully completed before continuing to the next step.
