In my experience, the most commonly accepted theory is that 100% inspection is only 80% effective AT BEST. That means that if your inspoectors are happy, noy outside concerns, well-rested, etc, they will catch 80% of the defects. This number goes d

Joe: Lemme see, you�re talking about controlling your manufacturing process within 4.6 defects per 100 opportunities or a 4,600 dpmo rate, a cumulative 99.95 acceptance rate, or a �2 sigma process, right? So, it�s fairly basic stuff, eh? First, yo
