My guess is they do not have much experience with snowballs in Delhi.
I have a idea though, think about the failure cost of a product. At the point where the failure occurs the cost is the manufacturing cost at that point. As the product moves downstream more content is added until the failure is detected. If this is an assembly, additional parts and labor would be added. If it is shipped to the customer…I think you get the idea. As the product continues beyond the point where the defect was created you have a snowball effect on the failure cost.
There, a real answer. (No claim regarding relationship to the question.)
