Which Ishikawa?


Technology

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 …


Technology

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

Technology

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


Technology

Ishikawa Diagram Classical Style

• One Group Activity (No stopping rule)

• Assumptions everyone in one room

• Sometimes vote afterward

• Ishikawa’s Book (Delicious Rice)

• South Dakota (Delicious Hamburger)

• 9th grade Native Americans (Fry bread)

End Day 1

• Let’s LIVE!

Begin Day 2


Technology

Frank J. Matejcik’sExtended Ishikawa (not Rika)

• Works with parallel work / multiple site• Work Oriented not Publication Oriented • Check completeness by capture-recapture stats • Allows for dissent to be documented• 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?• Harder Question: About Advising


Technology

Matejcik’s Trial Procedure0) Have group decide Categories & their place1) Individually make Cause and Effect Diagrams2) Make a group composite C & E diagram

(no new contributions)3) Complete a check sheet (mark last contribution)4) Individually make additions sheets5) 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!

Technology

Cause and Effect Sheet

• Group or Individual Name

• Circle Group or Individual

• Date

• Topic

• Space to draw


Technology

Additions/Dissent Sheet

• Individual Name

• Date

• Topic

• Round of Update

• Addition or Descent

• Space to draw


Technology


Technology

Check Sheet

• Contains a table

• Names run across the top

• Segment terms run down the side


Technology

Start the class C&E Charts


Technology

Begin Day 3

• Handout JSM paper

• What happened– Wednesday– Thursday

• Discuss completeness calculation

• Explain the follow up: EIPI


Technology

What happened Wednesday

• Group two finished the check sheets

• Group one started check sheets

• I talked with Stu about advising problems– Difficulty with admin survey– My mistake about 2nd step

• Calculated estimates of portion remaining

• It seemed close to being done, so ….


Technology

What happened Thursday

• I could complete the group one check sheet, combine both check sheets, and ….

• I started the group one check sheets and noticed that I need something.– Second individual Ishikawa– Mark up individual Ishikawa– Label both individual & group Ishikawa– Whine, Other ideas?

• Made these slides


Technology

Capture-Recapture


Technology

Estimate Completeness

• 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


Technology

Calculations from Group 2

• Make some assumptions. Bissel’s idea


Technology

Calculations from Group 2

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

What questions about our Ishikawa diagram?


Technology

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!
