No it doesn't mean the process is critical, but it could be a designated control item which is critical. Usually if a process is designated 100% inspection it means that it is not capable of achieving a Cpk of 1.33 or more.
ralphsulser, your previous message was brilliant, thanks
To be honest the variables with usually the companies used for measuring capability (i.e Thickness) are not the typical defects they search in the 100% inspection Test due to these Tests often search for attributive defects.
That´s why the companies still have Quality problems, the defects usually are in the field of attributive defect, due to continues variables are easier to control it via Statistical mode (Gauss), but attributive is more complex for enterprises, I would say that there are a few of them that really use attributive statical tools for attributive (Size of sample, Binomial, ;Mil standard, ...)
The general concept (I know that this is hard but is true) I heard from a Quality Manager was "
if you search more you will find more defects" or "The higher the size the higher the number of defects found"
It is corious that the kind of defects claimed by the Customers ofter are not put in the FMA, Transport damage, Handeling defect, bad shipment...
