Ezweld,
Would you please verify how you get the data ?
How it so you could make repetition on a destructive testing?

qwert,
WOW…THIS IS GREAT…There might have many SS project in your plant. This is a great oppurtunity with high payback….Could you tell us what kind of manufacturing your involve in.

Carlos,
Particle Size Distribution (PSD) are commonly measure using Laser Diffraction Spectrometry (LDS) thus giving the result in a certain distribution but not commonly Normally distributed. This could end up data set with outliers either on both side of your distribution tail including the outliers. Using MEAN of the data set could be…[Read more]

M,
No problem. Luke will not notice it since his hand will be cut-off. We will just replace it with both left.

Dearest Venkat,
Please contact Darth, BTDT, or Elbrin for this purpose. They might help you ??

Forrest,
Check DOE report if the result are in actual production use. Correlation of same measuring equipment. Attribute MSA for Inspector if any.
You might want to consider the following though it is not SS tool:

Luke,
Need not to get far. You’re already at the site (http://www.isixsigma.com)  where Sigma Calculator is available and ready to be use (Upper Left Corner). For more information, Sigma calculator are created with consideration to the Normal Distribution and with effect of the empirical data 1.5 Sigma Shift process variation. (Which some claim…[Read more]

Duhhhhhh,
Yes of course, the 1.5 sigma shift was accounted here. Your key board have two sets of Delete, Alt and Ctrl button for your consideration. Long and short term process variation was included in my example, thus I have provide note that this are for advance user only: (Left to Right)
Short term : Ctrl + Alt + Del and then Quick Format…[Read more]

Innocent,
Following instruction might be so tiring for you to follow? But could you please excert an extra effort to:
 Go to Search in this website 
Search/Entire Site/Type “Sigma Level”/ Click “Go”. The site will give you a bounce and lift you need. Or go to “Sigma Calculator” also in this site.
Note: Second steps are for advance user o…[Read more]

BJ,
You sounds like a typical boss in DILBERT’S Comic Strip………….
I could be at your service for a price of US$ 9,775.95 per month. If you like you could also stay at home and I could attend schooling for you. Sound great,  Huh ???

Andy,
How’s is that so?? Why not 46 or 48 instead ? Why 47 ? Any data?
Seems to me the effect of 1.5 Sigma Shift still scrounged in your brain and your giving your own version of non-data figure.
No data, no talk

Sigmaman,
For simplicity., lets consider only one factor (cause of variation) the amount of sugar to be put in a cup of coffee. Let say., you happen to establish a pretty good mixture combination for a cup of coffee whereas sugar amount is = 0.55 kg +/-0.026 kg.  Variance there are the those data difference away from the mean (0.55kg) eveytime…[Read more]

Sigmaman,
Variance in explain in layman’s term:
If you are to make an instant coffee, there are several causes of variation there: cup, coffee, sugar, creamer, water, spoon, temperature, humidity, mood and etc that you can think of.
 Variance are the difference in the amount from the mean of such factors each you mixed to make a coffee such as…[Read more]

Rahul,
I don’t exactly know if you understand what you are doing or you wanted us to jump on the mud pit that you have created. Frankly enough, you doesn’t understand or refuse understand the application of PDCA (Plan, Do, Check, Act) and DMAIC (Define, Measure, Analyze, Improve, Control) thus you wanted to make your life so complicated and…[Read more]

Chris,
This always dependent to your application suitability. Both will be sufficient if it was coupled with your own ingenuity and skills. Be sure to asked correct question and hope you get the best answer with application example.
Unfortunately, most of the e-learning or classroom experiences are focus on earning a nickel with a less qu…[Read more]

Wonderful. This is a classic one. I will put this one in my history log. Combination of DMAIC and PDCA. Please let me be your PADAWAN. Let me learn Force….I Like it…!!!.

Aman,
A good question will deserve a good answer. Then:
As a layman’s shortcut explanation, Six Sigma is not totaly came from a statistical analysis though it uses statistic on the calculation of DPMO / PPM under the area of a normal distribution, the effect of 1.5 sigma shift is applied. The sigma shift is an empirical data from previous stu…[Read more]
