In fact, WE have same sentiment. Unfortunately, this kind of spanking send wrong image on other peers. Who knows, maybe someday, somehow, we will be reporting to Six Sigma (MBB) practioner who doesn’t know how to do a Box Cox transformation.
Selecting SS BB project varies differently on every firm. Your company should have its own criteria to follow developed by your Quality Department or plant MBB. Criterias should be agreed upon by your top management inline to your business strategy and KPI’s.
Anyway, here are some of the list you could consider;
Results or B…[Read more]
Whoaaaww. Great !! Do you always agree with something !! Would you be cleaver enough to stand on your own feet and walk in your own dirty shoes?? It least, I have my own side of the land to stand to.
That’s what’s democracy means men. Sadly, I can do whatever I wanted to.
If you don’t like my post, dont read it. That’s it !! But don’…[Read more]
Demotivating, yes I should say. But, I have done it on purpose though. Who would you think will make the spanking here if you have seen someone straying on the great idea of SS methodology ? Or, your are one of those unfortunate people wanted to be GB, BB, or MBB in the promise of good fortune that it will bring to you.
Also, woul…[Read more]
Wow. Greenbelt is a great accomplishment !! But before I answer your question, would you be so kind to answer mine?
What is Six Sigma anyway?? Why is it useful to have such methodology in place?? Can we use Capability Analysis in determining how much PPM is outside the specification for a process with Exponential dist…[Read more]
Its only for your randomization purpose.
Say, you have ten standard (order) test run (sample) but you need to run it according to run order stated in your experiment.
If you are using Minitab, go to DOE>Create>Option> unclick the randomize run and you will see the result.
Wonderful. You have just pulled the string by yourself.
You are already in the right approach by convicing your company and to look-ut to other company that might be interested for your SS project (practice). Anyway, the best way you could do is to convicnce your immediate superior and show to him/her the advantages of using SS by a…[Read more]
You might be confused between SS Project and Quality Improvement? In doing a project, you need a strategic planning in consideration of everthing most importantly now; COST.. Impromtu thinking are not to be considered a project. You are paid to show the after (MONEY $$) effect. Please be guided.
Project are define as definite f…[Read more]

I guess that is the reason why is is called “DRAFTING”.
Anyway, defects are classified usually by the end user (costumer).Call a “VOC” meeting to list down thier requirements. Costumer have two category, internal and external. You might want to consider your internal costumer first. Else, you will be execrting all the effort and go brain…[Read more]
You can do this:
Minitab> Stat> Control Chart> R… input there your data and your done with the graphical analysis.
Why do you need specs in R chart anyway? Are you confused or something. You might wanna use Capability Analysis (Index)
It is very hard to show and explain something to your boss if you don’t know what is it you…[Read more]
Downfall of Six Sigma can be realized if you have ever encounter some obvious scenario below:
1.0 Utilizing a bunch of dim-witted and obtuse BB on a very simple project with savings $6K to $10K per year.
2.0 Re-training of fore mentioned BB’s whereas after training still doesn’t know how and when to use Box-Cox Transfo…[Read more]
Was I hit by my own light saber accidentally or what? Probably, I need one of those vader mobile to take me to Death Star for immediate surgery after that lazy post of mine.
The question need an answer eventhough I never believe in 1.5 sigma shift myself. Go back to our newbie question and hold your breath by lecturing me…[Read more]
My suggestion, please don’t do it not unless your Dilbert’s boss. It might give wrong expression to people that will read your card and ask you question regarding 1.520453 Sigma Shift. (Difficult huh??)
Base on your post, you know how to calculate the Zst, PPMst, Cpkst You know the formulae and how to use them.
To calculate Long term, just Subtract 1.5 to your Zst thus Zlt = 2, then you get the 22750.
Zlt = Zst – 1.5
