lin replied to the topic About the History of Cause and Effect Matrix ? in the forum General 12 years, 4 months ago
Not a dumb question for some. Some people like to know the history of things – about 25% of the population wants to know the history. It is like asking for the history of Six Sigma. Where did it come from? Why did it work in the past? Does what happened in the past imply it will work in the future? He asked a simple question. If you don’t…[Read more]

Hello,
I read your article in your continuing debate with Dr. Wheeler. In your real data example, you say:”The example data used in this discussion is a true enterprise view of a business process. This reports the time to change from one product to another on a process line. It includes six months of data from 14 process lines that involved…[Read more]

Not for me. My pages still take 1015 sec to load. Very slow response. Not that anyone cares, but I think I’ll just go play somewhere else.

lin replied to the topic Equivalence testing with ANOVA in the forum General 13 years, 2 months ago
No, not a book question. I’m trying to apply this as a way to compare destructive testing methods at different manufacturing sites. I have multiple moisture analyzers that I need to compare.

lin replied to the topic Equivalence testing with ANOVA in the forum General 13 years, 2 months ago
Robert,
Thanks for the reply. WHat I’m specifically trying to do is use a simple oneway ANOVA to show equivalence. It’s relatively easy to choose the “zone of indeifference” in a 2 sample equivalence test, since this is a pretty intuitive thing. For example, if I want to prove equivalence between the strength of two different materials, I wo…[Read more]

lin replied to the topic Graphing Attrition on a control chart in the forum General 13 years, 5 months ago
I disagree on using the p control chart. The probability of attrition is not the same for all employees. For example, younger employees tend to switch jobs more often. Thus, one basic condition for using the binomial distribution for the control limits in the p chart is not met.
I would use an individuals control chart.

lin replied to the topic Regression and Steepness of Slope in the forum General 14 years ago
Kris, good question, more subtle than some realize, Robert and BC have provided the basic math. Remember that if the slope is not statistically signficantly different from zero, then there is not a significant correlation between the x’s and y’s. The algebra provided by BC and Robert make that clear, as b –> 0, r^2 –> 0 too.

lin replied to the topic Excel Normal Distribution in the forum General 14 years, 1 month ago
If z = 1.85:
The area under the curve to the left of z = 1.85 is found using the following in Excel:
normsdist(1.85) = 0.968
You can also use: normdist(1.85, 0, 1, true) which is for the normal curve wiht average of 0 and standar devation of 1.
For the area under to the curve to the right of z = 1.85 simply use:
1normsdist(1.85) = 0.032

Just a quick add to RhinoNeil’s response. Several recent articles have been published regarding the iSSSM six sigma maturity model. Easiest place I know to find it is at the Instantis home page or perhaps ISSSP website. Our team has been wrestling with a similar question and has recently begun work to integrate the iSSSM maturity mo…[Read more]

As a motivational speaker and someone with a lot of credibility in the manufacturing field, Mario Perez Wilson is probably the best.
We used another “famous” individual first, and it was a disaster. Then, an exMotorolan recommended we contact Mario and it was unbelievable.
Our Six Sigma program runs flawless. We hired his consulting fir…[Read more]

What about Six Sigma in the blowmolding industry? Have you learned anything interesting about that? You’re not still giving away extra plastic for free are you?

lin replied to the topic Greenbelt certification from online university in the forum General 14 years, 4 months ago
Samyukta,
Why pay for training if you already understand the methodology? You could become GB certified through ASQ – though you might need to find a good Lean Six Sigma text and brush up. Good luck!  Load More
