I had never clearly understood the term six sigma before watching this video. Your explanation is so detailed and helpful. Thank you so much for making this video❤😭❤
Six Sigma is a term which I understood vaguely and in theoretical terms. It was difficult to articulate for me, especially if someone asks for explanation. But this here is the best explanation that I have ever seen on the topic. Kudos !!
So helpful and easy to follow. Next step, you could create a video showing the difference between Populations standard deviation and Sample standard deviation, and how each applies to SPC chart. If haven't already. Lean Learn ... a new Favorite. Thank you!
Such a blessing to have found your video. Even AI could not explain it clearly to me, it keeps apologizing for giving confusing responses. Thank you very much, Sir. Keep up the great work ☺✨
I’ve seen many people claim to understand Six Sigma and explain that 3 sigma above the mean and 3 sigma below the mean add up to Six Sigma (3 + 3 = 6). Your explanation is accurate.”
Thank you! I heard one guy say that six sigma means six defects per million opportunities…😂…I wouldn’t laugh- but he was trying to impress a young lady as they were looking at 6 sigma book…exact words: “why would anyone buy a book about six sigma…I can sum up the entire book: 6 DPMO…”
Thank you so much for this video! I’m getting a head start on my Six Sigma training and your explanation was so clear and simple. That is something that is greatly appreciated! Thank you! ❤❤❤
Thanks from India. I am a finance professional and had a successfully running food business which I compelled to wind up due to Covid19 pandemic. I just thought of adding a qualification to my resume and wanted to know what is Six Sigma. Your videos really helped me.
I’m not even in the course but was thinking about this and you broke it down so well to the point u feel like with more studying I could actually understand it even better. I’m waiting to start my project management course (CAPM) paid for by the army and I think I want to do six sigma next! Do you do project management videos as well?
No, but there is a channel that focuses on PM heavily. I’ll post a link to the channel at the end of this comment…six sigma is good but I would focus more on lean, Root Cause Analysis and Kaizen..I have a master Black Belt and speak from experience…you just need to know how to fix business problems and rarely do I see anyone using six sigma (actually never) if you see it on a job description, it’s because they want someone who knows how to fix a problem but the person writing the JD doesn’t know how to articulate what they want and feel that six sigma encapsulates everything-but it doesn’t! Six Sigma projects take 4-6 months to complete…businesses need faster response times! This isn’t tru for 100% of job postings with six sigma in the JD but I’d argue it’s about 98%. Hope this helps. Here is a link to her channel: youtube.com/@adrianagirdler?si=iYyd_YjT1ssMKW57
Probability enters when doing statistical estimations...calculating the probability of defects, failures, etc....probability of success...hypothesis testing....but in the pure calculation of 6 Sigma...no, it doesn’t. Does this answer your question? Thanks for commenting! Consider subbing if you haven’t!
Thank you, yes, really a blessing. I tried your example in Excel and it gave me a "hands on" experience, very useful. Next, I want to try it out using some material I am familiar with - but how many datapoints should I use, and what is the Six Sigma way of finding min and max limits?
Thank you for explaining it in a very understandable way. I understand that you have provided this example for a better understanding and it very much clarified my doubt, but i have one small doubt in the example which you have provided. You have mentioned that for a process to be 6sigma, the avg/mean should be 6 sigma away from the nearest specification limit, so in this example , is 3 sigma approach enough to achieve the requirement?
Excellent Presentation! Your videos clearly explain SS and also go beyond in showing how statistical measurements affect the desired/undesired outcome! I havnt seen anyone elses videos do thtr. Well Done!
This is the first video I watched that explained it really well, thank you so much! What if we only reached a standard deviation of 3 on the LSL side of the histogram just like the USL, will it mean that the restaurant food temperature range is not a six-sigma process?
Correct! You’ve got it. Appreciate the comment and question. Thank you for your support on the channel. I don’t get a ton of views because this field is such a small niche so I sincerely appreciate all the comments, likes, and questions.
Hello Chad, thank you for this clearly explained video. It's one the best out there! However, for this particular example, is it correct to say they are operating at 3 Sigmas (within USL) plus 6 Sigmas, which is sum up at 9 Sigmas (within LSL)? Sorry if this is a 'dumb' question...😮 Thank you in advance!
Not a dumb question at all. We would not sum up the sigmas because if we did, it would sound as if we’re operating at 9 sigmas which would be incredible! So the data set must be six sigmas from both the USL and LSL. Hope this helps.
@learnkaizen Thank you for coming back, Chad. So, in a 'layman language', what would you put about this process with 3 Sigmas on the right of the mean and 6 Sigmas on the left of the mean, and they are all within USL and LSL respectively, which is the VoC (i.e., conformity is guaranteed)?! Chad, for curiosity, what sort of Sigmas are they operating in here? Should we say 3 Sigmas? Please assist again here, and it would be very much appreciated as always 🙏
+HIMANSU SEKHAR PATRA thank you! I appreciate all feedback but really appreciate the positive feedback! Let me know if there other videos you’d like to see! Be well!

It would be nice to hear your journey, how you get the certification. I really like the trick of marking pages in the primer to quickly get relevant topics. Please share this kind of small tricks😊.
Great breakdown and explanation but when I square the numbers in the (x-xbar) I get a different value than your example. What am I doing wrong? Thanks!
@@learnkaizen ok thanks! I see what happened, excel rounded the Xbar and the (x-xbar) columns but it didn’t account for the rounding in the output column. Thanks for the quick reply. Still a very good explanation.
I have question, for CP or PP the formula = USL - LSL / 6*s; but when we look in the graph by definition distance between USL and LSL should be 12*s' s for it have a value of 1, then why in the formula we divide it by 6*s and not 12*s?
At the end, i do not understand. What is the intrepretation obtained from std deviations (Left side 6 deviations and right side 3 deviations)?. What will be the result given to hotel?
Hi, I am new to the concept of Six Sigma and want to make sure I am coming to the correct conclusion. In this example, we are saying that the mean temperature of the food that is actually being delivered is 133.28 degrees. However, the mean of the LSL (130 degrees) and USL (135 degrees) is the optimal temperature at 132.5 degrees. In order to have 6 Sigma in this example, the food preparation process needs to change so that the the mean of what is actually being delivered is lower and closer to the optimal temperature of 132.5 degrees. Am I even close to being on track here?
Almost…we can’t calculate the actual mean that gives us six sigma until a change is made to the process and new data is taken.the reason for this is because your sigma level will change and so will the mean. If you go back and look at the video at time stamp: 9.06, and count the total sigmas, you get 10 sigmas so there’s no way the current process could operate at 6 sigma (otherwise, we’d at least count 12 sigmas…6 on each side of the mean)…so, a change must be made so the variation of the temperatures shrink…creating a smaller standard deviation..:and allowing room for more sigmas between the mean and specification limits.
