    Steve,
    Thanks for reminding me of the educational and professional mediocrity that this site oozes due to your and MBBs participation and “substantial contributions”. I always enjoy passing by those cubicles on my way to the board that are filled with alcoholics like yourself who obviously have nothing more to offer than their cheap boozing and boasting of their own lack of substance. Keep it up. Your liver is having a party :-).

    Eric,
    As you are on your way to becoming not only a seasoned professional but also a qualified academic, I am sure that we will have the pleasure to meet each other one day at a conference and heartily laugh about the ignorance of the likes of MBB. Good luck with your dissertation. It’s quite a bit of work, but definitely worth the effort! And what better than a combination of professional experience, academic credentials and personal integrity! Good luck.

    Thanks, Waste-not!
    I look forward to meeting you one day at a conference, and perhaps relaxing over dinner to enjoy a good laugh!
    Well, I’m off to take my family out for my Mom’s birthday celebration (she won’t tell us what birthday it is…)
    Have a wonderful weekend!

    “There are many, beginning with E.S. Pearson in 1935 who have completely misunderstood the essence of Shewhart’s approach. They are actually unconsciously incompetent. I consider the advice to transform the data to be an example of gross incompetence and a triumph of computation over common sense.In his first book Shewhart wrote on pages 275 to 277 that if we knew the probability model to use, and if we knew the mean and variance for this probability model, then we could pick a value P that was reasonably close to 1.000 and find the limits of integration, A and B that would correspond to an area of P under the probability model. However, in practice we will never have enough data to ever fully specify a unique probability model, and even if we could, we would still not know the mean, or the variance of that model, so Shewhart turned this whole approach around. He said that rather than fixing P and finding A and B for a specific probability model. we should instead pick A and B such that, for ANY probability model, the value of P will be reasonably close to 1.000. And that is what three sigma limits do.Having said this three-sigma limits will work. They will work with the raw data, and they will work with the transformed data. However, while you may know what the raw data represent, how will you interpret the data after they have been distorted by a non-linear transformation? Extreme values in one tail will disappear while routine values in the other tail will become extreme, and you will be looking for assignable causes in all the wrong places and at all the wrong times.Let the reader beware, novices are still out there teaching nonsense to neophytes.Hope this will helpDon–Donald J.

    I am glad to see that there are some people on this site who can accurately quote Wheeler’s position. However, it is truncated and therefore misleading the reader into believing that by not accepting Wheeler’s position one is a “neophyte” and “incompetent”. The quote should also incorporate the core of the difference between the two schools of thought as stated by Wheeler and Chamber (1992, p. 11) 
    “As philosophical guides for manufacturing the engineering concept of variation and Shewart’s concept of variation have nothing in common. They have different objectives and different results. The engineering concept of variation has the object of meeting specifications. This naturally results in products that vary as much as possible, because anything within “specs” is considered “good enough”. In contrast, the object of Shewart’s concept is process consistency, and this naturally results in products that are as consistent as possible”.
    The British SR17 division developed its standards based on the goal for products to meet specifications! The British simply needed to survive WWII and for their purposes their type of control charts was sufficient: conformance to specifications. E. Pearson etc. knew exactly what they were doing! Any British textbook will tell you that the action lines etc. are appropriate for what Wheeler and Chambers accurately point out: quality control, i.e. conformance to specifications. And as the quote shows, Wheeler does not contest this historical fact.
    Now, if you read carefully the titles of Montgomery’s and Wheeler and Chambers’ books you will (not surprisingly) see that Wheeler and Chambers call their book: Understanding Statistical Process Control. Montgomery calls his book: Introduction to Statistical Quality Control! They are talking about two different things as Wheeler and Chambers correctly point out: “Therefore it makes no sense to try to reconcile these two concepts of variation. Management must adopt one or the other as a guiding principle: mere conformance to specifications, or continual process improvement”.

    “Conformance to Requirements, Zero Defects, Six-Sigma Quality, Cost of Quality and all other specification based nostrums miss this point. World class quality has been defined by “on target with minimum variance” for the past thirty years ! The sooner one wakes up to this fact of life, the sooner one can begin to compete. “

    This is the same guy that I said wrote the book Machine Process Capability and that Mensa candidate Spoon dismissed it because it didn’t say DMAIC specifically. The content is certainly the same as we see in six sigma. It was published prior to Harry’s semial work in the white and green books. It does apper to be the origin of the species.
    So to recap as we said before: the shift came from Smith regardless of what you think about it because it isn’t the point, the methodology came from Perez-Wilson, the tools have been around for ever, the idea of traing with Projects came from Juran as did the terminology concerning Breakthrough. The question remains what is Harry’s contribution. To satisfy Spoon/Reigle/Bash Me To he named Black Belts and he created the acronym MAIC because the D came from GE.
    Lets consider why he defends the shift so vigorously. If he doesn’t create a justification for the shift then he hasn’t made any real contribution beyond naming some things. That seems pretty simple and obvious not to mention it is a pretty insignificant contribution.

    Lebowski,
    Perhaps Dr. Harry is right …  Shainin’s pre-control method is suceptible to a 1.5 sigma shift and a high beta risk.
    The Shainin Pre-control method would also suffer a constant shift – unlike a Pre-control Shewhart Chart, where we use historical control limits to post maintenance productions runs.(If the fist -off falls into a new subgroup, it would be easy to form a new subgroup of size n from  (n-1) previous values, unlike Shainin Pre-control which uses individual values.
    Other facts do not seem coincidental either … apparently Harry reported to Shainin and worked in Phoenix – the only place using Shainin pre-control.
    In summary, I don’t think the value of 1.5 is a coincidental, or that it is a constant adjustment – as indicated by the miriiad of tables that go up to +/- 6 sigma.
    We now have two agruments against processes shifting hither and thither:
    1. Robust design using process desensitization
    2. Processes under SPC do not shift by 1.5 sigma. A chart set-up with CLs based on n=3, g=10 would only shift by about 0.6 microns, and then only until there were enough runs to re-calculate the CLs based on a more reasonable sample size.
    There are others … the world is multivariate not univariate.

    Ah, but where did Mario get his roadmap?
    In 1987, SABA asked the question of was there a logical sequence to all of the tools being taught. A couple of people working in Arcade, NY put together a flow chart of the tools that Mario took and wrote a book together capturing that flow of thought and tools. Clearly others in Motorola were already doing what Mario described in his book. Noteably were people in AIAG, Comm, and SPS.

    Andy,
    Shainin pre control isn’t “susceptible” to a shift – it allows for a movement in the mean in the green belt before its first level of correction procedures.  It doesn’t allow 1.5, it allows 50% of the spec limits –  1.5 happens to be the figure for Cp=1.0 (a rather uncommon situation), as we discussed previously.
    Your suggestion of Bill Smith having picked up his 1.5 in a misunderstanding from Shainin discussions seems quite likely.
    Of course, Pre Control’s corrections actually add variation.
    You are right about processes under control not shifting … even Bill Smith suggested his “as much as 1.5” for only uncontrolled processes.  He is of course quite wrong, there is no limit to how far things can go wrong when they do go wrong !

    Theo,
    Just to clarify the your first paragraph .. I just can’t imagine any process engineer back then setting up a Pre-control chart where the spec. limits did not correspond to +/- 3 s. Perhaps I’m wrong – there were many good process engineers in Phoenix and I would be surprised if they made such a basic mistake.

    At the risk of making you angry I don’t really care about the 1.5 sigma shift. The point seems to be that the origins were from some other contributor other than Harry pehaps even from someone from the wooden yoyo capital of the world. Harry has constantly tried to usurp the title of Father of Six Sigma and laid claim because of his contribution. Taking a lesson from Correction you look into everything and it looks like the only contribution we have is usurping the name Black Belt from the martial arts, renaming Mario’s process, and contriving a proof of the 1.5 sigma shift for no other reason than it is his only possibility for original thought in this process. Without someone like Reigle/Spoon/ Bash Me Too to worship at his feet he quickly becomes a footnote to the origins of Six Sigma.

    I am not sure where the newest twist that Dr. Harry has a PhD in Psychology comes from. His PhD is in engineering. His dissertation was on “training awareness at Motorolla”. That does not make him a PhD in psychology. Let’s stick with the facts.

    I think that just summarizes that whole debate. Isn’t it amazing to what lengths the kinds of Harry will go to create their own legacy! … and to what lengths their followers will go to catch that little bit of ray that eradiates from these “glorious icons”  in order to brighten up their sad and dull little lives.

    There isn’t a Motorola facility in Arcade, New York. At least not on an Internet search. It’s in the middle on nowhere.
    Let me guess Harry was working there and you hve proceedings from a Harry meeting that Mario copied to create the proceedings for his meeting so Harry is actually the father of Six Sigma.

    I agree we should stick with the facts. So what makes you think Harry knows anything about implementation? He outsources the implementation. He laways has and always will because he finds it demeaning to speak to anyone with less than a Phd.
    That becomes extremely clear in the first 10 minutes when you have to spend a week at the so called Academy. An entire week wasted with this egocentric clown playing with his Excel speadsheets on an overhead. Lets not forget the cigarette break about once per hour.

    It is exactly the point. If you watch the posts by Reigle/Spoon/Bash Me Too they seem to come at opportune times to side track a conversation such as this into some discussion about the shift. They want Harry in the spotlight but not under the microscope.
    We do tend as a nation to search desperately for heros but in this case I seems that Harry was searching to be seen as a hero. When you meet Lance Armstrong he doesn’t walk up and tell what a great bicyclist he is. The world knows and he doesn’t have to tell you. He never seems to forget the people that got him to where he is and if you look at the Harry dribble he has done this by himself. He has even made comments that attempt to make it look as if he hangs out with Deming, Juran and Taguchi. I don’t buy it.

    You really need to stay with the FACTS.  I strongly recommend you examine the Motorola documents and other letters presented posted to Dr. Harry’s personal website (titled Mikel J. Harry, Ph.D.) under the section called “Milestones.”  These documents sure don’t support your opinions. 
    So what is the world to believe?  Your opinions or time-dated Motorola documents?  At the end of the day, “facts talk and opinions walk.”
    PS.  You say he has even made comments to make it look like he hangs out with Deming, Juran and Taguchi.  Do you have the reference for this?  I would like to look up your statement.  Something tells me that this is just another contrived opinion without any way to verify what you say.  Again “facts talk and opinions walk” so please provide the reference.

    Here we go again. I asked Harry what he thought of Harry and he said he was the Father of Six Sigma. Facts may talk and opinions walk but idiots like you just never go away.
    On the thing with Deming, Juran and Taguchi. You want a reference to look up on a comment? There is another person who posts here who has heard him make the same comment.
    The Harry camp sees the wheels coming off and it scares you. We have seen the Harry third generation Six Sigma. We have seen Harry woo Montgomery in his quest for fire boy search for credibility and then got pitched out of ASU. Better to just fade away and settle for the undeserved footnote.

    Lebowski:
    I respect your opinions, but I respect facts even more.  Even greater are those types of opinions that are based on a logical interpretation of the facts, much like the philosophy of six sigma.
    It is now clear to me that your opinions stem from a basket of “sour grapes” and not from the vine of facts.  Maybe you are one of those that got left behind when the six sigma train pulled out of station.
    People such as yourself often feel somehow depreciated when others succeed at what they themselves can only aspire to.  I am sure you are a good person with some great experiences, but it is very apparent that your mind and heart is filled with contempt, especially for those that have enjoyed great success in those things you can only long for.
    Whether you like it or not, Bill Smith and Dr. Harry are both the fathers of six sigma.  Smith has been given credit for coining the term “six sigma” and Harry has been given credit for innovating the six sigma methodology and deployment system.  Even Quality Digest Magazine has named Harry as the “Father of Six Sigma.”
    As you post more and more unfounded opinions, you simply discredit yourself in the eyes of others.  Use more facts, references and journal citations and you will be amazed at how much respect you can create for “Lebowski.”  Until then, “Lebowski” is just another despondent poster that is long on opinions and short on facts.
    I mean these things in a constructive way, so please do not take offense.  My goal is to help you introspect and ponder your true motives.
    Best of Luck and God Bless You.

It looks like your nemesis who is so infatuated with older men with academic degrees truly has some psychological problems of his own.

    Okay Lebowski, here we go:

    A clear obsession with a father figure (.. I safe the time to count how often “Bash Me Too”  has used the term “father” over the past week or so)
    A shrill obsession with “being after someone” in order to “get them”, (on a quote, on an inconsistency etc.),
    Translate the “after” into its Germanic origin “after = ass”, 
    And there you have a nice little neurotic obsessive-compulsive complex that’s been driving this poor little chap to the highest “performance” in the absence of any hope of a climatic catharsis on this site.
     As  Th. W. Adorno once said, neurotic complexes like these are repetitive to the point of becoming boring because there is no solution to them. They are the solution. So, expect more of the same. The only thing that will change (and Bash Me Too has already proven that) is the promiscuous substitution of the father figure. First it was Harry, yesterday it was Wheeler, now it’s Harry again. So, let’s get ready for a neurotic repetition of Bash Me Too’s unashamed exhibitions of his twisted soul.

    If there is one thing that is a fact it is that the Harry entourage does not respect anyone that resides outside the Harry camp. You would not recognize a fact if it fell on your face and wiggled. If you go back through this string and the string that involved correction then you will see that my position has been pretty much solidified with the documents that have been presented during these posts. I was very specific about getting involved ad this post is a complete testimonial to that position. Anyone who does not worship at the church of Harry is ridiculed and hammered back into the mold by yourself Reigle/Spoon/Bash Me Too. So continue to post my friend and you continue to validate why I believed it was necessary to get into this post.
     
    Let’s look at what you just posted. Without any idea who I am I am sour grapes and was left behind. Because I don’t worship at the alter of Harry I cannot have any credibility? I don’t think that is true since you facts are derived from Harry to validate Harry while people such as SME offer up proceedings that document the existence of the process before Harry published the cartoon books and he was in attendance. That should bring up the question of why in Harry’s chronology doesn’t he give credit to Perez-Wilson for his contribution. The answer has to be to break that link to anything that ties back to the original creator.
     
    You have become to transparent over the last couple weeks. You have become the person that adjusts the confidence level to show significance. Testing to prove your point not to discover the truth.
     
    I do appreciate your concern but do lead a blessed life.

    Bash Me Too aka etymo(logy) a word you learned from a previous post of this thread. Mr. Dictionary abandoned you once more again :-). I didn’t say “the etymology of the word” is ….  I simply statated that the translation into German” of after is anus, rectum or ass. You’re really not very sharp!
    der After  = anus, rectum (look it up in a simple dictionary, no need to go into etymological depth, you fruitcake).
    Here is a list of other translations that adequately characterize you and what this site collectively thinks about you:
    der Arsch  ass, arse; butt, fanny*   am Arsch der Welt = in the middle of nowhere, in a Godforsaken hole (that’s where you live)   am/im Arsch sein = to be screwed up (that’s how you are)   Das geht mir am Arsch vorbei! = I don’t give a sh– (about that)! (that’s what we all think of your posts)   in den Arsch gehen = to get screwed up (that’s what happens to all of your post when, for example, you confuse “etymology” with “translation”)   Du kannst mich! (am Arsch lecken) = You can kiss my ass! (I’m not so sure about that any more after I’ve learned about your being “after” everyone on this site)    Setz deinen Arsch in Bewegung! = Get your ass in gear! (Get up and do something productive other than expose you silly little ego on this site).
    I’ll be glad to express myself more clearly if needed. Cheers and I hope you’ll choke on your venom and bitterness.

    The similarities to the Enron gang is amazing. They pulled off their deception for years with the same basic tactic. If you did not condone what they did or questioned what they did you were labeled as just not being smart enough to understand the level that they operated on.
    The Harry universe gets chipped away a little bit every day. With every post Reigle makes, with the self promotions of the Harry gang, etc they expose themselves. We have seen them bash the people who post on this forum but thank God there is this forum to post on and that people like Stan have held their position in spite of the ridicule trying to deliver the message he believes in.
    There will be a day of moral reckoning. The idea of a fraud charge will never happen. It won’t have the same resonance of Enron and the majority of the world will mostlikely not even be concious of it but people eventually reap what they sow.

    Lebrowski:
    Motorola internal news reports are a great source documents.  Sounds like you did not like what you read (if you read any at all), so now you want to reject it.  That’s OK, but your biases are in full dress.
    If you follow the documents, you will discover that Mario-Perez Wilson was one of Dr. Harry’s SPC students.  Coincidently, Mr. Wilson’s methodology looks quite similar to Dr. Harry’s Logic Filters strategy.  Seems evident (based on the facts) that Mr. Wilson attended Dr. Harry’s training and likely adapted the methodology Harry was teaching at the time, which by the way, dates back to 1982, 1984 and 1984 (according to the documents), but Mr. Wilson published his work after 1986.
    Mr. Labowski, everyone knows that “strings” of opinions at any website does not constitute “facts.”  You should want to reference the source documents, like the Motorola documents I have referenced.  These documents are in clear view of everyone, so do read them and learn.  Maybe once you digest the facts, you will feel better in your quest for the truth.
    I am happy you lead a blessed life and appreciate my concern.  I hope you appreciate it enough to meaningfully investigate the documents I have referenced and refrain from additional opinions that are not based on facts.

    Mikel Harry was not the founder of the DMAIC model but was the founder of the MAIC model.
     
    The DMAIC model was presented to general electric in 1996 in mesa az and general electric loved the define the system part (D) of the model and ran with it. I.e. world wide.
    Harry’s organization refused to accept the DMAIC model for several years until it became worldwide.
     
    His baby and paradigm was MAIC and he had a very difficult time seeing the need for the D part of the model. Harry deserves much credit for his contribution to six sigma. He is a salesman par excellence.
     
    As I worked with Harry he had a very difficult time seeing the systems influence on defect reduction. The MAIC model tended to deal with processes over systems.
     
    The D helped to solve that dilemma.
     
    Deming understood this weakness in the six-sigma approach to quality. No one that I have found understood variation as well as Deming and this includes Mikel Harry. Harry’s approach as is Juan’s is about putting out fires. Few will understand these words of Deming’s. I.e. few even most six sigma black belts.
