  1. TM 720Statistical Process ControlSpring 2008Dr. Frank Joseph Matejcik Extended Ishikawa Pareto Inspired

  2. Why is Frank here? • Promote my research activity • Suggest possible MSTM thesis alternative projects • Entertain / Excite Dean Jensen • I really like to talk about this stuff

  3. Two Motivations • Extend usefulness of a few of the Quality Circle basic tools for larger groups, multi-site use, and exploit their wide use. • Provide appealing and more simple alternatives to common qualitative (i.e. focus groups) and quantitative (i.e. Likert (1-5) scale questionnaires) procedures.

  4. EIPI

  5. Ishikawa Diagram withExtensions • Preview things • Deming Medal, References • Other Ishikawa’s • Person behind the method • Show Visio Tool • Classic Method • Modified Method • Complete?, Pareto / Compare to other

  6. "The right quality and uniformity are foundations of commerce, prosperity and peace." W E Deming (1900–1993)

  7. The fruit of SILENCE is PRAYER The fruit of prayer is FAITH The fruit of faith is LOVE The fruit of love is SERVICE The fruit of service is PEACEMother Theresa Programming creates beliefs Beliefs create attitudes Attitudes create feelings Feelings determine actions Actions create resultsShad Helmstetter Improvement sequences

  8. References Knovelhttp://www.knovel.com/knovel2/library/default.jsp • Juran’s Quality Handbook • Like a bunch of textbooks • Except no problems • Important authors, Al Gore • Ishikawa’s Guide to Quality • My page http://webpages.sdsmt.edu/~fmatejci/EIPI/EIPIhome.html • Web pics

  9. Which Ishikawa?

  10. Nerdy Japanese Professor & Quality Guru • ASQ Award (for Humanity in Quality) • Four points that totally encompass the beliefs of Kaoru Ishikawa: • Revolution in the philosophy of management; that is, management in which humanity is respected. • Company Wide Quality Control. • Effective use of catch phrases that are adapted to the trend of the times. • Quality first concept; that is, customer satisfaction. Kaoru Ishikawa Does not like …

  11. Nerdy Japanese Professor & Quality Guru • "QC begins with the interaction of people." • Quality Circles • eventually led to the development of team concepts around the world. • "Seven Tools of Quality“ • (1) histograms • (2) cause and effect diagrams (Fishbone) • (3) check sheets • (4) Pareto diagrams • (5) graphs • (6) control charts • (7) scatter diagrams Kaoru Ishikawa Only pic found

  12. Ishikawa Diagram

  13. Ishikawa Diagram

  14. Ishikawa’s book p24

  15. Ishikawa’s book p27Used as a prewriting aid, too

  16. Use Visio • Visio is under Microsoft Office on SDSM&T Machines • Use the top menu in this sequence to start File > New > Business Process> Cause and Effect Diagram

  17. Ishikawa Diagram Classical Style • Group Activity (No formal stopping rule) • Assumes everyone in one room (almost) • Sometimes vote afterward • Ishikawa’s Book (Delicious Rice) • SDSM&T (Delicious Hamburger) • 9th grade Native Americans (Fry bread)

  18. Frank J. Matejcik’sExtended Ishikawa features • Response to Dean Jensen’s suggestion • Works with parallel work / multiple site • Work Oriented not Publication Oriented • Check completeness by “accepted” stats • Allows for dissent to be documented • Uses the same familiar graphic • Can replace “Qualitative Methods” • Used in a well reviewed NSF proposal

  19. Frank J. Matejcik’sExtended Ishikawa Efforts • Classroom trials • Using for Improvement in my 10AM F06 class • Sim class wants “Well written problems” • Tried Again in 10 AM F07 class • GES 115 Why pick SDSM&T? compass exam, move • About Advising in IE 241 did calculations • Andreas Eikland fictional examples • Needs for projects • Trials in industry, government, community groups • Usage aids for all of the above • Statistical questions on sampling

  20. Matejcik’s Trial Procedure 0) Have group decide Categories & their place 1) Individually make Cause and Effect Diagrams 2) Make a group composite C & E diagram (no new contributions) 3) Complete a check sheet (mark last contribution) 4) Individually make additions sheets 5) Update the composite C & E diagram (only from additions sheets) 6) Update the contribution check sheet (Mark Last Contribution) 7) Stop or go to step 4) If stopped, vote or rank. DISSENT SHEETS CAN BE USED AT ANYTIME!

  21. Cause and Effect Sheet • Group or Individual Name • Circle Group or Individual • Date • Topic • Space to draw

  22. Additions/Dissent Sheet • Individual Name • Date • Topic • Round of Update • Addition or Descent • Space to draw

  23. Check Sheet • Contains a table • Names run across the top • Causes run down the side

  24. Capture-Recapture

  25. Estimate Completeness from advising question • Use CARE-2 from Anne Chao http://chao.stat.nthu.edu.tw/softwareCE.html • Get estimates number of causes • Formulas from my JSM paper allow calculation of portion remaining

  26. Calculations from IE 241 • Make some assumptions. • R. Ufuk Bissel’s idea

  27. Calculations from Group 2 • D^ is the portion remaining • See CARE-2, site, data file, output file? • To finish sample more

  28. EIPI

  29. Pareto and Juran

  30. From Ishikawa p46

  31. From Ishikawa p47

  32. From Juran’s Handbook

  33. We can ask • How much money would you spend? • How much time would spend? • What portion needs to be changed? • Of course, which one would you change? • Which five would you change? • And report it on a Quality Circle level, maybe a middle school level!

  34. EIPI compared to otherIn your work consider these • New and not recognized • Qualitative completeness measured • Without short list or over sample • Quantitative questions readily developed • Few quantitative questions • Questions give Pareto ranking • Without wrong priority • Much at a quality circle level

  35. Summary: EIPI extends QC tools, simple alternative • Extended Ishikawa • Very general, Widely taught • A simple qualitative method (i.e. focus group) • Workable for large group, multi-site, • Can sample and verify completeness (unique among qualitative methods?) • General Pareto is a simple quantitative method (i.e. Likert scale questionnaire)

  36. EIPI What’s Next • August Statistics conference with a poster analyzing this freshman data. • Menuize surveys to general Pareto form • Looking for TM projects to • Use your ideas, really (Aaron, Andreas, Brice) • Try it at work, community group, government • Use / Develop other software • R and GNM • MARK • Second sample selection • Develop or try Statistics for general Pareto

  37. Thanks for Listening!
