    The fact is that we are not scrapping hardly any product at all.  It must improve though.  There is new competition that is taking a small piece of the business.  We have to improve to make…[Read more]

    yes, i agree with you. 
    We are still in a “sales” phase of six sigma.  What we are trying to do is make certain that we are doing the best on GR&R before we go and say we have to have money for inspection equipment etc.  We have no intention of doing nothing about it.  We do, however; want to be certain that the GR&R we submit is the best we can…[Read more]

    I dont feel like its fair to say we arent taking it serious? I would compare that to making fun of somebody that is having a hard time reading. Just because you can read well doesnt mean they dont take learning how to seriously even if they are going about it all the wrong way.
    The fact that we are doing an R&R and understand that it failed and…[Read more]

    Thanks for all the responsses so far.
     
    This is where we are now.
     
    Repeatability-Equipment Variation = 66.72%
     
    Reproducibility-Operator Variation = 187.94%
     
    R&R = 199.44%

    There is no (-) tolerance as the defect is only in one direction.

    cool…a beverage list.  I’ll present that to my CEO instead of MBB justification.  If i inundate him with samples perhaps i can win him over!
     
    Thanks Ben for an actual response.  I appreciate it.

    great…now any real help?
    I’m aware that the company doesnt have a clear vision.  We are trying to fix that.  If we can have some success then it wil be much easier to justify extra training and resources.
    So does anybody have any good advice or tips about justifying a MBB?  What does a GOOD MBB bring to the table that most people will not se…[Read more]

    so yeah this is a shameless bump to the top.  this is like one of the least complex questions i’ve seen on this board and everybody ignored it!  Everybody too good to answer newbie questions?  :)
    Thanks for your help
     

  • newb started the topic Z term VS Sigma in the forum General 18 years, 2 months ago

    can anybody please explain the difference between sigma and Zst/lt.  I mean i know sigma is the deviation and my understanding is Z is a measure of predictability.  Why would some people only measue sigma and others only use Z?
    thanks
