  • Shift happens….I doubt sigma (standard deviation) is zero unless you have poor resolution on your gage which would imply a failed gage R&R if checked.

    @MBBinWi

    Hey my friend and colleague….I wasn’t considering your post when I gave my advice. :)
    You give good advice, sir.

  • @rbutler I’m not discounting this technique (and I’d always advocate something other than using Johnson transformation). :)

  • share the data

  • Specs must be transformed also using the same function.

    I would advise against doing a CCD immediately. Confirm the cause/effect of the experimental design and you can always attempt to augment with CCD points later if all factors were statistically significant, etc.

    Consider why you’re doing a SIPOC.

    1. Get you aligned with the team on how process BROADLY works.
    2. Alignment with you and your project champion.

  • If you have a theoretical standard for getting X parts out of meters of material, then your quality number could be X created / (Y meters * Z theor parts/meter). Some will tell you they recommend the standard parts/meter but often that standard is a deflated balloon because wastes become part of that standard.

    Remember the trend is most…[Read more]

  • @sharatpavanreddy Did you search our site before asking your question? We have a section of content on VOC/Customer Focus: https://www.isixsigma.com/methodology/voc-customer-focus/

  • DW — It looks like you didn’t search our site before posing your questions. They have been asked and answered multiple times on the forum in the past 10+ years.

    Good luck with however you proceed!

  • @abyola My advice still applies. We can’t read your mind about your intentions. You asked a question and we answered based on the information we had.

    What do you think the answer is? Why/why not? The more details you provide, the more likely a discussion is to happen. For example, why is this on your mind? Do you think X while colleague Y thinks…[Read more]

  • One needs commonality of purpose, alignment with business needs, resources for improvement efforts, well scoped teams, and well selected teams. Proper application of tools and project management of the resources help.

    May sound a bit basic but…

  • Johnny, it seems you’re confirming variation in measurement across testing devices and using those test devices as the repeats.

    Be aware that if so…you won’t get an idea of variation of each device if it’s one TEST.

    Especially if it’s not time consuming, consider a gage R&R for each test stand using your 10 motors, 3 operators and go ahead and…[Read more]

  • @abyola It looks like you didn’t search the site before posting your question. You’ll find many answers if you spend some time looking for them.

    I guess Anonymous doesn’t mind if the plane lands on the runway?

    It appears that this and your other question are homework questions. Did you search our site before asking them?

    What do you think the answer is? Why/why not? The more details you provide, the more likely you are to get a response. The more effort that the iSixSigma audience sees that you’re putting into figuring these answers…[Read more]

  • 1. Remember that a relationship doesn’t mean that there’s cause and effect.
    2. There may not even be a relationship but you can’t quote the correlation coefficient solely. You need to see what the p-value is for statistical confidence.
    3. Is the data properly measured? If not…would cause the r value to drop.

    Just a few extra thoughts.
