> you're not going to "solve" the problem by fixing all the broken power seats you test; you're going to go figure out where in your manufacturing process/supply chain things are going wrong I think the point is that examining the failing seats will lead you to the points in process that should be fixed. Therefore you can fix the issue more efficiently than going through the whole process. Similar as with knowing details about failing software tests. Imagine I hide the information about seats and tell you 10% of the finished cars have "some" defect. Where would you even start looking in the factory?
