    No need for snarkiness. This is a forum in which knowledge is exchanged. If you did not want to answer, why did you reply at all?
    I too believe in the “teach a person to fish…” method, but you took it too far. Your bedside manner needs some polishing. 3 years, 1 month ago

  • In Six Sigma problem solving, it is often important to calculate the likelihood that a combination of events or an ordered combination of events will occur. Understanding some of the basic concepts of probability […]

  • You could try the Shainin Isoplot. True Shainin Red X users might argue about it, but an Isoplot is basically a “Gage R” (a single person measures a group of parts twice – i.e. Repeatability).

    However, I agree with Chris’s comment. Why are you not checking reproducibility too? Unless you have a very specific scenario, I would use a Gage R&R. 3…[Read more]

  • I wasn’t thinking of autocorrelation. I was wondering if there is an issue with either the resolution of the gauge or maybe with the sampling. If I draw my sample from the same location in a vessel, will I get a very similar pH result? 3 years, 8 months ago

  • I’m OK with your choice of tools. Not sure what the dot plot gives you, but that’s OK.

    Looking at your data: Your process mean is shifting too much. Your batch-to-batch variation is too large. Eliminate what the problem cannot be, and whatever is left must be the source of your variation.

  • You could use colored candies (such as Skittles) to demonstrate the Pareto Principle. Be careful with M&M candies – somebody has been optimizing their process. The distribution of colors is getting very uniform making it hard to demonstrate Pareto. I have been using colored stones lately. They are inexpensive and you can find them at any arts…[Read more]

  • When beginning a deployment, you have to ensure that certifications lead to benefits. If you do not, you are just hanging wallpaper in your office while lining the pockets of the consulting world. A […]

  • I wouldn’t make a decision on this data without knowing the R-squared values. Assuming linearity could lead to incorrect decisions.
