I will be at the AAMA/AIAG Southern Automotive Quality Summit this month in Birmingham. Then later this year in September at the AIAG Quality Summit in Detroit. There will likely be other shows/conferences as well as some customer/prospective customer visits.
I am curious what's happening out there to get you out of the lab, office, shop floor, manufacturing center or wherever you may work.
I often see spec lines displayed on an Individuals chart. The argument for adding them is that anyone can quickly determine if the measured value is in or out-of-spec. One argument against adding spec lines to an "X" chart is that the focus changes from process stability and signals to simply acceptability or not. What are some other reasons you think spec lines should not be displayed on an Individuals chart?
