I suggest you click on “terms” and get rid of at least one of the highest order interactions, like “ABC” .
When you reduce the terms by taking a term out of the analysis, the degrees of freedom available for the error terms will increase and you should be able to see p values.
Also, you might want to click on the graphs button and…[Read more]
The equation, r = +/- 1.96 sqrt(STDev), seems to use 1.96 for the 95% confidence interval that should include the mean measurement value. The term “repeatability” actually refers to the standard […]
I skipped a step in sharing the search…
Here is the reference that the anonymous comment said was in error:

You could also get that from…[Read more]
Well, I checked out the articles from Quality Progress in 1997
( http://asq.org/qualityprogress/past-issues/index.html?fromYYYY=1997 ) and did not find the referenced article.
So, continuing on as a nerdy Sherlock Holmes, I found this comment:

I’ve recently seen some good results combining Value Stream Mapping and Discrete Event Simulation using Simul8.
I have never used that formula, preferring to use Excel’s built-in functions for cumulative normal distributions…but this is referred to as:

There is no accrediting organization for six sigma / lean six sigma training providers.
The relevant question might be: after you are certified, will your certification be accepted and will you be considered credible as a certified green belt or black belt or whatever.
Now, I’m a certified Black Belt and Master Black Belt, from the…[Read more]
What are you trying to mistake-proof: the tendency to have missing information in the first place, prompting the follow up…or something in the follow up procedure?
It sounds like you were given a set of individual cycle time measurements…and they want you to estimate the cycle time 80% of the time…Which is a rather vague request.
If they wanted you to tell them a value that 80% of the cycle time values are less than, then you would want to sort the data, and find the value that 80% are…[Read more]

Can you clarify your request a bit?
LSC and USC – I assume you mean Lower Specl Limit and Upper Spec Limit?
Are you measuring yield for a continuous parameter? If so, what are the limits for that […]
Several aspects, largely financial:
1) According to research, it takes 10 to 20 times as much investment to gain a new customer as to retain an existing customer – it makes business sense to do your best to retain the existing customer base. Research also shows that the major cause of customer defections is loss of confidence in the…[Read more]
Oops!! I missed the sarcasm…I guess you just come across as such a nice guy, it didn’t occur to me that you were using sarcasm. My bad! :)
You are correct…
Thomas Edison could not have been a TRIZ user. Edison passed away in 1931. TRIZ was invented in Russia, starting around 1946… shortly thereafter, Josef Stalin sent the inventor of TRIZ (Dr. Altschuller) to Siberia….
Dr. Altschuller’s research of patents, that led to the TRIZ approach, would very likely have…[Read more]

Samantha – I think MBBinWi was right about Concurrent Engineering – you can research it, but it likely won’t fit in well with the overall theme of your research paper.
The overlap between DFSS and Systems Engineering starts at the front end – understanding the customer…[Read more]
Thanks for the challenging request.
1) First, do your best to clarify with the executives / management what you are really trying to optimize, and how to measure it. How can you measure “effectiveness”?
“Costs” sounds clear, but how will they know that you have optimized “costs”?
Mostly, the type of…[Read more]
