qualitycoloradoParticipant@qualitycoloradoInclude @qualitycolorado in your post and this person will
be notified via email.To add to Marlon Brando’s note:The 7 tools were advocated by Dr. Kaoru Ishikawa. He packaged them together as the Seven Tools of Quality Control. He really only “invented” the Cause-and-Effect diagram, in its “fishbone” form (also known as the “Ishikawa” diagram in his honor). Cause-and-Effect diagrams can take other forms (like Tree Diagrams), and others were doing cause-and-effect analysis, but Dr. Ishikawa packaged this together with the other tools and pushed forward the fledging science of quality control.The 7 tools are the cause and effect diagram, check sheet, control chart, flowchart, histogram, Pareto chart and scatter diagram.
… hope this helps ….
Best regards, QualityColorado0December 20, 2006 at 8:45 pm #149340“The seven QC Tools, if used skilfully, will enable 95% of workplace problems to be solved” – Kaoru Ishikawa 1989.
He is right too !!!0December 20, 2006 at 8:49 pm #149341As an exam bonus answer, you could mention that Shigeru Mizuno identified and promoted 7 NEW tools to supplement the old ones in 1978 in light of changes in the economic environment. The new tools are:
Relations Diagram, Affinity Diagram, Systematic Diagram, Matrix Diagram, Matrix Data Analysis, Process Decision Program Chart and Arrow Diagram.
0December 20, 2006 at 10:54 pm #149354It was Dr. Harry and he actually advocated that there were 8.5 Tools of Quality. I can provide his mathematical derivation if you wish.

PreethiParticipant@PreethiInclude @Preethi in your post and this person will
be notified via email.the 7 tool is not enough for a quality managemnt it requires more detail information and six sigma can be a better tool…

ShrinivasMember@ShrinivasInclude @Shrinivas in your post and this person will

K.M.DateParticipant@K.M.DateInclude @K.M.Date in your post and this person will
be notified via email.To Dear All,
I have been keenly observing the Tools/Methodology fight!
Once the Management of the enterprise gets rid of the wrong strategy of ‘recognizing the value by brand-name’, the fight for brands like SS, TQM, etc. etc. will stop automatically. But I know, thats not going to happen, even in the distant future! So the skillful assemblers of knowledge-components, make merry for ever, by creating newer and newer brand (assemblying/re-assemblying old/new knowledge components) every couple of years, when organizations loose the charm of the existing product!
Merry Christmas to All

0December 21, 2006 at 5:05 pm #149396Ah yes! The 1.5 tool shift! I forgot about that! One must not forget to take into account the 1.5 tool shift.

The wonderful thing about the additional 1.5 tools are they can be anything you want them to be – kind of like the 1.5 sigma shift?
Have a great Christmas, everyone!0December 21, 2006 at 8:43 pm #149406
Ken FeldmanParticipant@DarthInclude @Darth in your post and this person will

Just spoke with Reigle and this is what he said. The eighth tool is the Spaghetti Diagram to help you figure out where you have been as you wander around in a daze attempting to make sense of the SS jargon. The last tool is the half axxed use of hypothesis testing. The .5 comes from the underlying assumptions of normality which the latest threads seem to have shredded. Combine the 1.5 with the more well known 7 and you have the 8.5 tools of quality.0December 21, 2006 at 9:11 pm #149410Good one Darth.
…. but why does it cost $4K to be trained in 7 tools and $40K to be trained in 8.5 tools ?0December 21, 2006 at 9:42 pm #149413
Ken FeldmanParticipant@DarthInclude @Darth in your post and this person will
be notified via email.Excellent observation. It is my understanding that the 10.0 shift in training costs is tied to the fact that someone, who shall remain nameless, has to pay off some debts, round up some new cattle, maintain a big boat and pay to have an entourage of worshipers.
0December 21, 2006 at 10:35 pm #149421Debts !? I thought that when one found a goose that laid golden eggs, one didn’t have to worry about debts ?
Or was that a goose who found a golden egg ?0December 21, 2006 at 11:22 pm #149423
Ken FeldmanParticipant@DarthInclude @Darth in your post and this person will

Give me a call when you get a spare 5 mins.

Are you an ex-employee of Harry ?
Sounds as though you may have some interesting stories to tell about gooses being screwed and cooked ?0December 22, 2006 at 1:58 pm #149446

Interesting, many of your comments and posts on this forum, bashing Dr. Harry, have been based on the friends you have, which one can conclude at one time were friends of Harry or at one time fed of his innovations? Interesting observation indeed!
Friends like that, who needs enemies! Thanks for sharing.
Cheers!0December 22, 2006 at 6:34 pm #149468
Ken FeldmanParticipant@DarthInclude @Darth in your post and this person will
be notified via email.I disagree with your conclusions. There have been many posts regarding Dr. Harry and the development and evolution of SS directly from those that were there at the time and had personal interaction and knowledge of his efforts. Granted, the rest are heresay and less value should be put on those comments.

Thank You0October 20, 2007 at 1:22 am #163405There are also 7 New QC Tools:
Relation diagram, Affinity Diagrams, System Diagrams, Matrix Diagrams, Matrix Data Analysis, PDPC Method, and Arrow Diagrams.
(ref: The Seven New QC Tools, Practical Applications for Managers….by Yoshinobu Nayatani; 1984)0October 20, 2007 at 3:54 am #163406More tools don’t mean better quality.
Learning to use even one tool excellently is far more beneficial than using many tools poorly, as most people do.0 -
