"Passing the strict certification required by the customer is not the end at all, it is only the minimum requirement of the customer.  Our quality control cannot set target at 60 or 70 points in percentile, but 150 or 200 points. There is no upper limit for quality, if we scored 100 points, not because we happened to be able to achieve 100 points, but because the standard was 100 points maximum."
