Is six sigma actually useful or is it just junk science? I'm

Does anyone even know what the fuck I'm talking about?

its a corporate meme like SAP, its not a genius system but it has fine fundamentals for the general case, much like SAP it does overcomplicate things but thats going to be what happens whenever you try to standardize everything between so many different areas

It's a method to minimize the numbers of defected products.
If your company works on a field where it is necessary use it. If it's cheaper to make some waste goods, you can fuck yourself with it.

Nothing can replace competent management of competent employees. If you don't have that, no fad process is going to help you.

Some companies have that but see six sigma as the 'extra edge' though. In my experience procedure is good for certain tasks, but for jobs that require a certain amount of judgement I don't think it would work well.

6S Black Belt here. It's useful for very specific value streams but is by no means a management system. Lean aka Continuous Improvement is a much better holistic and self-supporting system for managers to cascade demand and priorities while empowering the front line to raise and solve problems.

Take the Space Shuttle program for context. Six Sigma would ensure that as few as possible of the thermal heat tiles would be defective. Lean is like mission control, monitoring everything and focusing on the mission first and the details second.

Quality Medical Engineer here and desu 6sigma isn't really needed. Nearly all companies operate to 3 sigma which in a normal distribution allows for 99.7% non defective products. 6 sigma costs companies loads to implement under the guise of saving money and you'll get 99.99966% non defective products. So I'm not convinced that the difference is really worth all the extra time and effort. I mean in the medtech industry everything is double and triple checked so the defective products will be caught. I think samsung were the first to do it. I'd say it's more for bragging rights

How long did it take you to become a black belt and is it worth the effort?

Lean Management does make a lot of sense to me, very simple and logical approach.

I'm in pharmaceutical manufacturing and it is a huge concept in the plant. There are a bunch of people employed just to continuously monitor and improve the 6 Sigma processes implemented. I am not completely sold on it and definitely think it is a corporate meme but I do believe the original ideas are very helpful (reduce waste, save time, improve product output) but I think it overly complicates a lot of basic concepts

I was trained in it but for someone in maintenance, i didn't find much use in it. I think it is good for optimizing manufacturing, but you don't need to take it to six sigma levels. Economic reasons may make it expensive and not benefitial.

its just comon sense in japanese

“Efficient market theory [is] a wonderful economic doctrine that had a long vogue in spite of the experience of Berkshire Hathaway. In fact one of the economists who won — he shared a Nobel Prize — and as he looked at Berkshire Hathaway year after year, which people would throw in his face as saying maybe the market isn’t quite as efficient as you think, he said, “Well, it’s a two-sigma event.” And then he said we were a three-sigma event. And then he said we were a four-sigma event. And he finally got up to six sigmas — better to add a sigma than change a theory, just because the evidence comes in differently. [Laughter] And, of course, when this share of a Nobel Prize went into money management himself, he sank like a stone.”

My company is paying for my green belt.

I am milking them for all i can.


By the time im done with them, ill have my CFA, MBA, and 6 Sigma (hopefully black belt)

Is that a real dilbert strip?

>tfw I went to school in michigan for business and it revolved around manufacturing even though I studied finance
>mfw the finance stuff they taught me is is literally 15 years out of date
>mfw all the profs are fat people with tenure who were successful in the 80s before manufacturing moved to SEA

I could have studied something useful and timeless like math or sales but nooo I learned this Six Sigma bullshit I will never ever apply. How did I not understand a business education was geographically dependent?

Please give me some context on that quote.

>>1109897
Can you explain this further? Doesn't make a lot of sense without much context. I think it's trying to say the guy who invented 6 sigma was a tool...

>>1110690
Yes.

It was an industrial and research statistical standard that has been turned into a corperate meme by upper management without technical backgrounds.

I'm a systems engineer and I'm going through this bullshit right at a new job even though as an engineer it is literally my job to already solve problems.

It's from Charlie Munger, chairman of Berkshire Hathaway. I think it's referring to Michael Jensen as he apparently publicly debated Buffet regarding efficient markets, and he did win a nobel prize
