Robino,This my 3rd attempt at responding. You do not have sufficient evidence to reject the null for a couple of reasons:1) Your “noise” is too great. The noise is the denominator in the test statistic (in this case, “Z”). The noise is a function of the hypothesized p (what your are testing against) The as your hypothesized p approaches p .5,…[Read more]

Great suggestion. I was getting ready to direct to the same example. Nice demonstration of Attribute Agreement Analysis.

Nats,I read Stan’s postings as more of a deeper inquiry, not as a challenge. It is kind of tough to understand a person’s tone with the response. I didn’t interpret his response as picking on anyone else’s education or lack thereof. eteP

Dr. Kosaku Yoshida is there. He is great a professor, who studied under Deming at NYU. I still steal some of his material when I teach.

Yep. That United. I am really pulling for Sir Richard Branson. I am ashamed to say my son turned two in July and he became a United Premier traveler this month. That could be seen by some as child abuse. I like to say to say that every 100,000 miles flown on UAL takes one year off your life. I have dropped 14 years. After all that, I am…[Read more]

We need a separate thread for important stuff like this.

No more reviews. Done. I walked away.
Now I rake leaves and talk to my son, who has seen his dad more consecutive days, than he ever has.
It’s been especially nice not having to deal with United (“We’re not happy, ’til your not happy!”) Airlines every weekend.

I don’t see it. I think Hemingway’s “theorems” are “central” to life in Key West.

No, I think he had jet skied to Cuba.

He shoots! He scores!
“Monty, tell our contestant what he has won!”

My quick response is we don’t use p-values to assess the stability of a process, we use control charts to help distinguish random from non-random variation..05 is a default value, but you should not be “blinded” by it. It is completely appropriate to change that to .10 or .01 in some cases. It helps you assess risk of over reacting (rejecting…[Read more]

Want me to read to you? (It just worked for my two year old)

Back in ’98, my wife and I were trying to enjoy a quick drink in Sloppy Joe’s and a guy sits down next to me and says, “Please don’t tell me you came all the way down to Key West to teach Six Sigma to Sloppy Joe’s. The guy was a Green Belt I had trained while in Stamford. I bought him a drink and assured him I wasn’t there for that!

Oddly enough, I missed Stan’s invite. Hmmm…
Enjoy South Africa. Look forward to talking with you when you return.

Attendance is based on your ability to construct and interpret a dive profile and Jimmy Buffet trivia. If you think you can hang, then you are invited.

Sorry. You have to earn your right to attend.

Another thought is to try to identify organizations that have embraced Six Sigma (another touch challenge) and than use the estimate of around 2% Black Belt certified. That will is a very rough estimate, because of the constant churn of Black Belts.

Rob,I am not sure what you are referring to. The R square will always range between 0 and 1. Pete

SixSigmaShack,It appears you have 4 columns of data. I am assuming the cycle time is the last column and the first three are inventory and incoming volumes. What is the third?

Yeah, sadly I the conferences I wish to attend on the location, and time of year. Miami in February? Count me in! Rarely is it based on the keynote or the workshops.
