7. Seven major tools of SQC n Histogram n Check Sheet n Pareto chart n Cause and Effect fiagram n Defect Concentration diagram n Scatter diagram n control chart

8. Control charts help reduce variability n Idea: you calculate a middle line [average], and upper/lower lines, based on historical data n Then you let the process proceed n if you get points outside the UCL/LCL, worry [or maybe 3 points in a row]. n Main types are X bar and R -avg/range

9. X bar chart n The center line is X double bar, the average of the averages… n in other words, X bar is the average for one day. X double bar is the average of these averages n R is the Range, R bar is the average of these n The UCL/LCL are +/- [R bar][A2] n A2 is from your chart

10. Homework for SQC n Do a control chart. checksheet,pareto diagram,histogram for your book problem 2.5 n For extra credit: do a control chart for something in your life/job n 2.5 doesn’t have a bunch of days to do averages on, but have X bar be X double bar, and R bar be R…..
