  • Stan, thanks a lot for the help.
    Let’s asssuming scenario as this: lowest negative value -9, my project lower specific limit is 5. To calculate Z value I need to do below:
    1. Add 10 to my all data to transform data to be positive
    2. Box Cox transform data to normal distribution….. transformed data available.
    3. Use step 2 transformed data  t…[Read more]

  • You still haven’t answered his questions!!  What is a better tool.

  • Chris,
    You have hit the cord when saying “you set the criterion based on severity of wrong decision, good or bad.”.  Kind of like evalutating a risk reward ratio.  In my particular instance, the important question is “what is the risk of being wrong considering the continengy plans that would mitigate the effects of being wrong”
    I’m not f…[Read more]

  • Chris,
    thank you for the response.
    It’s not a question of validity of the measurement system.  Here’s an elaboration.  If I determined that the root cause of a defect was the incapability to identify it as a defect (yes/no or go/no-go) and to validate that, in fact, it was a cause then I would need a statistical method to associate the caus…[Read more]

  • Bill,
    your example is an excellent way to illustrate the relationships between the distribution curve and the control limits of the n and np charts.  From a very pragmatic point of view, the assumption that p is constant throughout the process, really limits it’s application succumbing to applying I-charts. This is the reason I seldom use n and n…[Read more]

    Jim,
    thanks for the reply. What you are referring to is the “roadmap” of the strategic objectives/mission.  Unfortunately, (in my humble opinion), we have no shortage of executives that can tell us what the company needs to do to attain financial targets but very few that have the leadership and even the courage to take on the risk of developing…[Read more]

  • Thanks “seen it..”
    That certainly helps clarify the notable differences.  I’ve cut a paste it into my library of important articles.
     
    I appreciate the input.
    Frank

  • Thanks Chris…so there really is no connection to the formula except to say that the probility distribution and the n and np chart elements have the same conditional requirements.  That’s my take.  thank you

  • Folks,
    Why could an organization need a Master Black Belt? Obviously, to coach and train BBs and other belts and in addition to lead top priority projects. He/She has also a role to remove barriers and maintain collaboration of executive and project type works.
    Deployment Champions should act differently, i.e. must champion the deployment. It…[Read more]

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

    I spent 3 years in Japan studying a Master of Science Degree in Company Wide Quality Control, and never heard about “six sigma” by itself, however, all the techniques I learned in Japan I am applying when I came back and got my Master Black Belt certification.
    In japan, they don’t call us black belt, the call us Quality Engineer, but the…[Read more]

    Chaos Nut – and you now quote Freud?   Are you also a Freudian Nut?  At least you now provide citations and don’t, by their absence, lay claim to wisdom that you don’t possess.  And, now that I am duly edified, your point in this posting was? 
     Please, if you post in the future, keep the same forum “name” because others could then use EVE (Es…[Read more]

  • Nwajei replied to the topic Doubt on Sampling in the forum General 16 years, 2 months ago

    Chaos Nut – you really are a nut.  I am really disgusted with you.   You profess to know complexity theory but you plagiarize your postings.  I knew that I had read what you just posted somewhere else – and I found it.  You lifted it entirely (verbatim) from Energetics as Self-Organized System: Methodological Aspects, by R. Siugzdaite and S. Nova…[Read more]

    V.,As a thought, since many are coming onto this forum asking for assistance with day-to-day problems using proven Six Sigma analytics and you are offering an alternative approach – work function.  Why don’t you answer their questions using a parallel approach, first by going ahead and applying routine Six Sigma analytics, e.g., Chi-square, re…[Read more]

  • Tim F.,I was having enough difficulty tracking with V., who I believe to be a very bright fellow, but your posting really confused me.  What are you trying to say with your incredibly repetitious paragraph structure?   Is there a message within the message?   You could challenge The Rule of Four’s Hypnerotomachia Poliphili for most obtuse commu…[Read more]

  • V., I’m beginning to see the juxtaposition of our thoughts.  The thinking is along a somewhat common line, but you are taking the literal and deriving theory and I am attempting to move from theory to the literal – and not doing it as well as you have, I must note.  Interesting.  As in naturally occurring dendrites versus “unnaturally” occu…[Read more]

    V., you are too smart a guy not to know this, so as I feel compelled to walk down this path of exploring your response, I feel a bit like I’m walking into a set-up, but venture into it I will.  You espouse the contributions of dendrite analysis…[Read more]

  • Nwajei replied to the topic 360 feedback in the forum General 16 years, 3 months ago

    Stan,
     
    Would you agree that a portion of your effectiveness in an organization is based on how you are perceived by your organization?    And, if so, would you agree that it’s better for you to know how you are perceived than to not know how you are perceived?     Better in that if there were negative aspects of your personality or delivery…[Read more]

  • Nwajei replied to the topic 360 feedback in the forum General 16 years, 3 months ago

    Ghero – I fear that your concerns go much deeper and broader than 360-degree feedbacks.   They (360’s) are just a tool, use them or not, value them or not, it matters not.   Don’t get emotionally caught up in what is really just an esoteric debate of little consequence with folks picking at each other.  And I say that not only as a blowhard egoti…[Read more]

  • Nwajei replied to the topic 360 feedback in the forum General 16 years, 3 months ago

    It is obvious that Mike Carnell has not fared well in the 360-degree feedbacks that he has had in the past.   It is possible that some of the traits that might be useful to a Six Sigma deployment leader, e.g., non-compromising, headstrong, pronounced sense of unerring judgment, etc., would not necessarily rate well in 360-degree feedbacks.  Of co…[Read more]
