  3. First Homework • Part 1 • Find an interesting item on www.asc.org about QUALITY, mildly edit it down to 100 words or less • Copy and paste, count words [must be less than 100] • Electronically communicate to me: • email to me [TEXT ONLY, no attachments!!] • Part 2: • make a comment on • www3.ltu.edu/~anneberg/qc.html • don’t be anonymous, so I know who you are!!

  4. American Society for Quality and Quality in Manufacturing • Wonderful resources for info, especially when the class is over • ASQ has certification programs: Quality Engineer, Reliability Engineer, etc. • www.asq.org AND www.qualityinmfg.com • Juran and Deming are among the VIPs of the quality genre

  5. More Introductions • I have an online questionnaire that you must fill out… [homework #1] • www3.ltu.edu/~anneberg/qc.html • I want to get a good email list going, and also know what topics you’d like to see • EXTRA CREDIT opportunities: • find my dissertation/title/year: email me 1 line • find a marathon time of min: email me 1 line

  6. SQC = Statistical Quality Control • Montgomery, our course book author, also has a SQC book [I use this as a reference - he also has a Statistics, Probability, and Prob/Stat book, among others] • Quality Improvement leads to increased productivity • 80/20 rule - Pareto handout

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

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

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

  10. Homework for SQC • Do a control chart. checksheet,pareto diagram,histogram for your book problem 2.5 • For extra credit: do a control chart for something in your life/job • 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…..

  11. Homework summation • Questionnaire: www3.ltu.edu/~anneberg/qc.html AND COMPLETE!! • Go to www.blackboard.com/courses/EME6403 and add some item from ASQ or Qualityinnmfg.com to the discussion • Small data analysis…..
