Hi there! I'm and undergrad currently studying quality engineering and I have a question regarding the use of MIL-STD-105E in industry. I was wondering what are the reasons for normal inspection being the only sampling plan used by some companies? I was thinking along the lines of ensuring that quality is retained while at the same time having a higher probability of acceptance according to the OC curve but I'm not sure. Secondly, I believe that such a practice is not advisable as the switching rules would follow the ideal OC step function and therefore is more preferred. Is this correct? Any opinion is greatly appreciated thanks!
