  • @Hajo, thanks for the clarification on the sample size. I agree that with 15-30 samples there will be few data points and that you will have to extrapolate – hence the manual curve fitting using a french curve. As for rare events – I’m not so sure. If you are running a capability analysis one of the assumptions is that the process is in…[Read more]

  • Thanks, @Hajo – that is the part of the Minitab program which corresponds to the method referenced in the book by Bothe. The only thing I find odd is the requirement for >2000 data points. I’ve used this method dozens of times over the years and I’ve never had the option of asking for >2000 data points. The cost per sample for most of the…[Read more]

  • The wholesale price is the amount of money a wholesaler would pay to a producer. That price will be the cost of production plus some percentage above production cost. The wholesaler, in turn, sells the product to a retailer for a price equal to what he/she paid plus some additional percentage to cover wholesaler cost and provide a profit to the…[Read more]

  • Some graphs update automatically some do not. For example a basic process capability graph won’t. I don’t know the exact “routine” but years ago I was told if there’s many calculation results on the graph, the auto update isn’t available.

    @MBBinWI gave you best way to check.

  • @KingDon What approaches have you seen/used? Why do you think those management styles work or not? Why are you asking?

    It does appear that this is a homework question–unless you’re going to put forth some effort to show your engagement/interest in the subject matter, it is highly unlikely you will get a response here. The iSixSigma audience can…[Read more]

  • Is this related to an earlier inquiry?

    Have you considered an MSA?

  • I’m sorry but your rolled throughput availability concept doesn’t make sense to me. If I had a production line based on 2 cells that were in series and both were down 50% of the available time and they didn’t […]

    Let’s get some spirit. :)

    In the spirit of innovation, it’s interesting what ideas are out there.

  • 7S?

    I’m old fashioned and struggle when organizations say we need 6S because we also want safety……what is 7S?

    FYI, I highly value 5S AND Safety but I don’t think the 2 concepts should be confused even though 5S highly impacts safety.

    I don’t understand John’s point. CTQ is the X’s necessary to create a quality product or service.

    However, it should be demonstrated with data why an X is deemed critical to a process to perform well.

  • Are you referencing the limits within that a checkweigher will not kick out product?

  • Nice to see the document of what you’re doing. @kkiru

    It looks complicated and causes more questions in my mind but you are closer to your process.

  • Neither – get a copy of Measuring Process Capability by Bothe – read Chapter 8 – Measuring capability for non-normal variable data. According to other posts to this forum Minitab has the Bothe method as one of their options in the capability calculation section.

  • @MBBinWI well stated…I was just focusing on his aspect but for other readers–your advice is top notch to “remind” me of the potential to misinterpret on the counter argument. :)

  • Consider your project charter. What are you trying to accomplish?

    If you’re trying to increase uptime, throughput, or … they will all impact your data needs. Is the data your asking for numerical? I hope so and if it’s pieces/hr or …. then the data should be continuous.

    It’s tough to just answer if something’s continuous or discrete but I…[Read more]

  • So is your data cycle time or is it something else?
    If it is something else then what is it?
    a) Is the derivation a case of binning or otherwise converting cycle time into some kind of Likert scale rating?
    b) Is the derivation a mathematical manipulation of some sort that converts the cycle time in some kind of units into a different…[Read more]

  • I’m not trying to be mean spirited but if you don’t know which hypothesis to use then you didn’t know what to tell Minitab with respect to calculation of sample size and power which means your output from Minitab may not have any bearing on the question you are trying to address.

    The two hypothesis you have described apply to two different…[Read more]

    @KKiru

    Nobody is going to summarize information for you that you can find by searching the site.

    As I said previously, if there is a particular point you are confused about, be specific about what you don’t understand and why it doesn’t make sense to you. Ask a clear question and you may get some help/direction in return.

    Hi, Chris is correct- in the Limits area of the dialog the first tab is Parameters- you can enter a historical mean and standard deviation there.

    @MBBinWI– you are also correct. :)
    @cseider– let’s catch up soon.
