Would appreciate a copy of the project.Missing DOB, bad date formats, signature variation, mailing address information resulting in rework and long cycle time[email protected]

Change (is good) agent:
Oh my gosh! Where to start?No cost benefit from any projects? How were they selected as good projects to begin with?Fire your Six Sigma implementation consultants, and tag the money as a financial benefit!If you don’t have a seasoned MBB to guide the BBs and GBs, then get one. Failing that, this mentoring function should…[Read more]

“I am disinclined to acquiesce to your request”Mathematics is not democratic. “…It means no.”P.S. Tea will be served where half the cups have milk first and the other half have tea first.

Figured it out for myself. There is no direct relationship between the references. They both come from a third, common source.Lurking variables!

Nonsense? I’m not sure what you mean.I agree about the difference between analysis and modeling. I see analysis as the part from the mathematicians talking about tasting tea. The modeling part is more the practical side – what makes sense in the light of the experimental setup and the real situation.MINITAB is great software and defaults are well…[Read more]

This looks like the references from page 2.16 of ARD-version 3.Is that so?;)

Include the main effects – don’t be a cowboy statistician.This debate, loosely called ‘school of thought’ is the battle of the statisticians vs. the cowboys. Six Sigma is about removing the ‘seat of the pants’ philosophy and replacing it with solid, data based methodology.’A lady declares that by tasting a cup of tea made with milk she can…[Read more]

Darth:
I will send you a simple example you can run in Minitab where the 2-way interaction is significant while the individual factors are not.The numbers are simple enough that a hand calculation shows the effect on mean-error and degrees of freedom.Interested?Post a temporary email address – the forum is regularly ‘spidered’ by spammers for addresses.

Statistical tests are all about calculating a signal/noise ratio. This test statistic is compared against a theoretical value based on the distribution of the sampling error. The test statistic could be an F value, a T value or otherwise. This methodology requires an accurate estimate of the pure, random error (noise).In a DOE, You must include…[Read more]

Yes, you were at the back of the room with John. It was fun to see George react to the questions.As for the rest of everyone, a patent is granded to an invention, method, or apparatus. The ‘formulae’ is part of a method, hence an algorithm can be patented. This patent applies to software.My point in the post was that the elusive derivations…[Read more]

Mike:
I did raise my hand and ask once. We were at a conference in Toronto. You were at the back of the room while he was pitching his ‘Lean Six Sigma for Service’ book.The reply went through four stages
– the handwaving was quite amusing during the talk
– the discussion afterwards was evasive
– his http://www.profisight.com site does not…[Read more]

If you have a long section of tubing (say 100 ft) and THEN cut it into 100 1 foot sections, the distribution of lengths will be non-normal. The lengths are not independent: for every section that is a bit too long, you have generated one that is a bit too small. These distributions will be skewed, but still does not explain the non-normal…[Read more]

Forum:
I am an active member of a quantitative finance forum.http://www.wilmott.com/They ask members to post to one of a few different categories such as – software- technical- jobs- student- books- off topic- brainteasers- careers
It helps focus the discussion and target the audience
The forum is easy to navigate and search
IMHO

Nice to hear from you,

I was training some MBBs at GE with the HR MBBs and Quality Leader for HR in the room. When we were talking about Gage R&R, I gave an example of doing a Gage R&R for the annual HR performance review session so famous at GE. During the training of HR people, they are given a number of portfolios of candidates and asked to assess the placement of…[Read more]
