    The big and I mean really huge misconception about Lean Six Sigma is that so many people see it as a physical object.
    DonΒ’t believe me? Just surf through the various Six Sigma websites (to include this one) and you will see 100Β’s if not 1000Β’s of statements like:
    Β“Six Sigma does not workΒ”, Β“Six Sigma saved our company millionsΒ”, Β“Six Sigma is not goodΒ”, Β“Without Six Sigma we would be much better offΒ”, Β“I blame Six Sigma for the economic turn downΒ”, Β“Six Sigma is the best thing since sliced breadΒ” and so forth.
    ALL of these statements are completely ridiculous. Six Sigma is not a Β“thingΒ” you use. You cannot give me a cup of Six Sigma, you cannot invite Six Sigma to dinner, you cannot move Six Sigma around, and you cannot even show me a picture of Six Sigma.
    For those of you who do not know, Six Sigma is a methodology a concept. Nothing else. Six Sigma will NOT save your company money (even so it is promised by various irresponsible consultants), Six Sigma will not drive your company into the ground (even so it is stated by incompetent people who do not understand Six Sigma), and Six Sigma is not the methodology for everything.
    What saves your company time and money are the people within the company. Not Six Sigma. What drives your company into the ground are the people within the company. Not Six Sigma.
    If you use and understand the concept/methodology of DMAIC correctly, then yes, the PEOPLE using the Six Sigma methodology can make better choices and save your company money. On the other hand, if you do not understand and use the concept/methodology incorrectly, then yes, the PEOPLE using the Six Sigma method will cost your company a lot of money and possibly drive your company into the ground.
    In laymenΒ’s terms, a statement that a pipe wrench is bad and does not work, makes no sense. If you try to use a pipe wrench to fix a computer board, is it the pipe wrenches fault? Of course not. It is the person behind the pipe wrench. The same goes for Six SigmaΒ…simple. Now of course if you do not know how to use a pipe wrench, then it will ALWAYS be the wrong thing. The same goes for Six SigmaΒ…simple.
    Now for those of you who like to come on to this site and make really stupid remarks about how bad Six Sigma is, I really have to ask myself how dumb are you. This is a site for SIX SIGMA, for those of us who UNDERSTAND Six Sigma. You may as well go to a plumbers convention stand up and yell that all pipe wrenches are useless and should be gotten rid of. Plumbers know the value of pipe wrenches and when and when not to use them, just as most intelligent people who visit this site know the value of the methodology/concept of Six Sigma and when and when not to use it. Β 
    Maybe now we can start focusing on learning how the methodology and tools behind it can help us make better choices and decisions.

    Are you saying that Dieter may be misguided or are you saying he is
    ignorant?

    Now how in the world did you know I had him in mind as I wrote this? I have been misguided myself a few times in the past, but put in the effort to find out the truth (whatever the operational definition of that may be) myself. Reading some of his posts I would have to tip on ignorant. Not sure he even wants to know.

    In brief are you saying it’s not guns that kill people it’s the person holding/cleaning or droppingΒ the gun that kill people?

    Yep,
    as people with toy guns cannot shoot other people no matter how mean they are :)))So, I would say that people and the method are both necessary but not sufficient conditions. When we say that six sigma works, I guess, we subconsciously add “in the hands of the right people”, as opposed to “astrology works” as you can not conceive any group of people who could make it work.regards

    No you are correct.
    I think the phrase is a bad workman blames his tools
    orΒ 
    a bad manager blames the tool rather than person he employed as that’s betterΒ than admitting he employed the wrong person.

    Ahhh… you just have to think “Out of the Box” (grin)when discussing SS as an object that does something.

    Well, of course it’s not guns that kill people (unless you hit them over the head withΒ it very hard or many times), it’s bullets that kill people.
    Remember Chris Rock’s solution – Charge $5000 per bullet and see how many drive-by shootings we have.

    The point is, why do others not see this? It is so simple, but every time I come back to this forum, it is always the same people trying over and over again to try an explain it to them. I look at Mike’s, Stan’s, Darth’s and other responses, and admire the patience they have. Keep it up.Plastic

    I am sure from time to time a gun has been used to kill someone. As Tom Cruise says in Collateral “…… the bullet killed him.”

    Plastic,
    Nice post. When I hear people say SS doesn’t work you have to ask what part. Is it the basic stats, Process maps, hypothesis tests, DOE, etc. They all worked before we had SS. So if SS is a methodology that essentially combines known proven tools into a methodology where the output of one is used as an input or information for asubsequent step – how does that not work? I guess a t-test works if used by itself but if used on a SS project it may or may not work. No logic to that.
    Just my opinion.

    Mike.
    Ok for the pedants out there.
    It’s not the bullet that kills people it’s the person who puts the bullet in a gun and then pulls the guns trigger that kills people.
    Bullets/Guns/SS/Lean/TQM don’t have a mind of their own we do and the more powerful the tool the more chance of using it badly.

    Plastic,
    Thank you for the compliment and I am sure Stan and Darth thank you as well.
    What I enjoy reading here are lightening bolts of clarity we get such as your original post. These are the things that, for me at least, cause a person to think about the issues that show up here, in a much different light.
    Regards
