    What determines acceptable when using PP and PPK?
    What determines Random when using PP and PPK?

  • It definitely sounds like a fairy story.
    Shainin’s pre-control approach has been shown to increase variation.
    Can we expect similar fairy stories about Mikel Harry perhaps ?

    Can you get me the e mail id of the CEO marketing of Airtel , Pls this is urgent

    It is the same as the World’s 100 Worst Statisticians list.

  • Ang replied to the topic doctoral thesis in the forum General 15 years, 11 months ago

    Why not go all the way :
    18 = 1.5 + 1.5 + 1.5 + 1.5 + 3 + 3 + 1.5 + 1.5 + 1.5 + 1.5
    Mikel would love the tolerance stack-up wouldn’t he, the fool …

  • Ang replied to the topic doctoral thesis in the forum General 15 years, 11 months ago

    The 1.5 is not worth of a doctoral thesis. It’s history should be enough for anyone to see it is crap.
    Which 1.5 anyway ???

    Bill Smith’s uncontrolled 1.5 batch variation
    Harry’s 1.5 drift
    Harry’s 1.5 correction
    Reigle’s dynamic 1.5
    Add them up :
    1.5 + 1.5 + 1.5 +1.5 = six sigma !!!!!  Voila !!!!

  • Ang replied to the topic 4.5 sigma Control Limits in the forum General 16 years ago

    BB is correct but a little blunt.  Here’s the full history in brief:

    Harry confuses 1.5 Shainin Pre Control green band limits with control chart limits.
    Bill Smith observes “sudden shifts” due to special causes and broadens tolerances to Cp=2.
    Mikel Harry derives +/-1.5 as a “shift” in the process mean, based on tolerances in stacks of…[Read more]

    I’m afraid I can’t see the point you are making about Andy and Isoplots. Are you saying he doesn’t understand six sigma ?
    What is your understanding of what is six sigma ?  Is there are fixed list of what is in and what is out ?  From what we read here, 3.4 DPMO, six sigma tables and isoplots seem to be out, what is in ?
     
     

  • Ang replied to the topic Beyond SS? in the forum General 16 years ago

    Nahhhh.  I think we should just take SS and remove all its faults. We should therefore call our new approach “VACUUM”.

  • Ang replied to the topic Question About Six Sigma in the forum General 16 years ago

    Absolutely. You can say that again
    Theoretical backing of six sigma is non existent !
    It runs on blind faith.

  • Ang replied to the topic Question About Six Sigma in the forum General 16 years ago

    Dear Lisa,
    “Why can’t Six Sigma be the same everywhere?”
    There are a number of reasons.  While SS has been a big earner for Motorola and the SS Academy, most quality consultancies have jumped on the bandwagon, each with their own versions.  Many have seen the flaws in SS and even teach SS under a TQM banner, simply because the name “six sig…[Read more]

  • Excellent post Stan !
    It is exactly the same situation that occured with Compuserve and GIF graphics. Compuserve claimed rights to the GIF format and royalties from anyone using it. Motorola is in the same position as Compuserve.
    We might expect to see a statement like this:
    “Cost to users will be a $10,000 one-time licensing fee and a royalty…[Read more]

  • Ang replied to the topic Waste of money in the forum General 16 years ago

    There is now widespead acceptance that six sigma has been padded with a great deal of statistical nonsense. The nonsense comes from two men – Mikel Harry and Rigel Stewart.
    With the increasing number of six sigma failures, such as that of SammyTexas, it is time that six sigma was purged of Harry’s and Stewart’s nonsense.  For example, why do…[Read more]

  • Ang replied to the topic Question About Six Sigma in the forum General 16 years ago

    I can understand your difficulty. 
    Here is an example of six sigma theory taken from Reigle Stewart, a director of the Six Sigma Institute:
    “1) Declare a random normal model such that NID(100,10). 2) Declare this model to possess an infinite degrees of freedom. 3) Call this distribution the “theoretical model.” ”
    In other words, “assume a n…[Read more]

    You sad little fellow Stan,
    I can see it now, meeting with Factory Manager and R&D Manager.  BB says:
    “I’ve just done a 4 week course !!!!     Look I have a certificate and everything.   And just look at the color of my belt !
    I’m going to take over production and do some experiments.  ”
    Get real little man.
     

  • Well kids, it’s like this … everything was fine then along came some guys who wanted to make lots and lots of money … so they invented a whole lot of rubbish and called it six sigma … that’s why it’s very hard to understand.

  • Ang replied to the topic Six Sigma in the forum General 16 years, 2 months ago

    I’m well aware that six sigma does not believe in people :
    Mikel Harry says “When you look inside the inner workings of Six Sigma deployment and implementation, you see a money factory.” “The key is to make fear a driving force” “In short, numbers-oriented thinking applies to people as much as it applies to processes and products.”
    These are…[Read more]

  • Ang replied to the topic Six Sigma in the forum General 16 years, 2 months ago

    Your question should be “how does six sigma offer companies a competitive advantage over TQM ” …
    Answer : “It doesn’t”.
