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!
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?
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.

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?
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.
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!
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.
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.
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.
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!
Very good explanation.. But for the denominator of SAMPLE std deviation formula.. It should be n-1 instead of just n.. Denominator of just n or N is used for POPULATION std deviation.
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 🙏
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?
So in the above example the hotel is operating at 3 sigma level or 6 sigma level ? Also why is the USL considered to be the nearest limit where both USL and LSL are at equal distance from mean?
It’s at 3 since that’s the point of reaching the USL. The mean is not equal distance. The mean is closest to the USL...I actually count them out in the video.
@@learnkaizen The mean that is considered in the example is that of the data set and not the mean of USL and LSL right? Is that how we are supposed to take the mean every time.
Yes. The mean is the average of the data set...and yes, the mean will be the average of some data set - always. Unfortunately, when this is taught - most instructors show the histogram without demonstrating how it’s all constructed which causes a ton of confusion. Great questions! This use to confuse me as well - (20 years ago - I’m old 😂) hope this helps clarify!
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?
So because they are not operating at 6 sigma, does that mean they need to further dissect their process in order to get there? Like find out why they are not achieving their target and make adjustments until they do?
Yep. You got it...if they want to achieve six sigma. Sometimes it depends on the business. For example: if your product is inexpensive with loose tolerances - you may not want or need to invest in six sigma. Hope this helps.
Request: Would you be able to provide actual data to understand and for my review. I love to play with numbers for 6 sigma example. For an example it works well. Perhaps I can use for my training for upcoming workshop. 👍🏾
I used data in the example. If you’re looking for raw data from a real world example, no - I can’t provide that kind of data. However, you can use whatever raw data you have…then follow the same process as indicated in the video.
I new in my heart, or I should say my instinct told me that you would not be able to provide requested data because perhaps it does not exist. Thus I am not surprised to receive the answer, I predicted.
Data exist everywhere. Im not following your request//prediction. For ethical reasons, I don’t typically share data from companies I’ve worked with. As for actual raw data, help me understand what you’re looking for…do you want the temperature data points in the example? I’d encourage you to go and find data, stratify it and apply the formula in the video. The learning points are: how to use the formula and to define six sigma. Not to provide raw data…
+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!
Chad Burroughs Thanks for replying. It would be nice to see some videos about practical ways how to study and pass ASQ greenbelt/blackbelt exam. 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😊.
hello, I'm a student of industrial engineering. I am working on a machine utilization/productivity improvement project. I want to calculate the six-sigma level for the machine's utilization. Due to the improper flow of the raw material, the machine is required to shut off. If the current utilization is 25% and looking forward to increasing it to 95%. how can I calculate the six-sigma level for the machine's current utilization rate and after improvement?
If I understand your statement: Your problem is that steady flow of raw material is insufficient causing 75% utilization loss of equipment. Current State = 25%, Target = 95%. You have everything you need to solve the problem. Why do you want use six sigma? Utilization is the correct measurement to determine success after improvement. (OEE could also be used but brings in other variables like Quality and Performance based on CT, so not really necessary in your case)... I would not use Six Sigma for what you're trying to use it for...if someone is asking you to do this, a boss or professor, I'm sure you can force the formula but it's absolutely unnecessary and should never be done in my opinion. After 20+ years in various industries (Automotive, Aerospace, Life Science, Biotech), I've never seen Six Sigma used for Machine utilization...because we use utilization and OEE.
@@learnkaizen Thank you for your response. My project flow is: Define the problem, Measure the necessary data, Analyse the measured data (utilization rate, efficiency, and productivity), Improve the situation, and control (if required). This flow is almost similar to the Six Sigma DMAIC. So that's why it is asked to calculate the current six sigma level.
Ahh. Okay…I see where this may be confusing. That’s why I have a love/hate relationship with six sigma…DMAIC is a great methodology for systematically solving problems…but think of it as a tool that accompanies six sigma…So technically, Six Sigma and DMAIC are separate tools…six sigma is about reducing variation to improve yield rate…DMAIC is like any other problem solid tool..PDCA, 8D, 7-Step, etc…does this help? If not, let me know.
@@learnkaizen again thank you. So it is necessary to calculate the current six sigma level in this situation? Is it okay if I write the thesis title as "Application of Six sigma DMAIC for productivity improvement" without calculating the sigma level?
I wouldn’t include six sigma in the title because technically you’re not using six sigma…an interesting research would be to utilize six sigma to understand the variation/fluctuation in raw material…that’s the underlying issue causing insufficient machine utilization. Even then, it’s a stretch but you could get the necessary numbers to complete the six sigma formula…this is where I’d focus my energy…if you use DMAIC, during the M(easure) phase, you’d measure the current state utilization…under analysis, you’d evaluate why..which leads to the variation in raw material delivery…then use six sigma to set controls on the material delivery with signals that escalate if delivery variation reaches exceeds parameters. This is just off the top of my head. You have way more knowledge on what you’re trying to accomplish. I don’t want to take you off course..these are just suggestions based on the limited information I have. Hope it helps and doesn’t confuse you…
My frustration comes form the squaring done at 7:35 in the video and maybe you can help me. We are forced to use a very basic calculator for the certification test. When you multiply .83*.83 you don't get .682 The calculator gives us .6889 What am I doing wrong? I am fixing to go insane here trying to figure that one issue out.
Thank you so much for explaining this concept with so much clarity. I only wish you went further to explain how this can be used to improve the process and always make it within limits

If I understand your statement: Your problem is that steady flow of raw material is insufficient causing 75% utilization loss of equipment. Current State = 25%, Target = 95%.
You have everything you need to solve the problem. Why do you want use six sigma? Utilization is the correct measurement to determine success after improvement. (OEE could also be used but brings in other variables like Quality and Performance based on CT, so not really necessary in your case)...
I would not use Six Sigma for what you're trying to use it for...if someone is asking you to do this, a boss or professor, I'm sure you can force the formula but it's absolutely unnecessary and should never be done in my opinion. After 20+ years in various industries (Automotive, Aerospace, Life Science, Biotech), I've never seen Six Sigma used for Machine utilization...because we use utilization and OEE.
@@learnkaizen Thank you for your response. My project flow is: Define the problem, Measure the necessary data, Analyse the measured data (utilization rate, efficiency, and productivity), Improve the situation, and control (if required). This flow is almost similar to the Six Sigma DMAIC. So that's why it is asked to calculate the current six sigma level.
Ahh. Okay…I see where this may be confusing. That’s why I have a love/hate relationship with six sigma…DMAIC is a great methodology for systematically solving problems…but think of it as a tool that accompanies six sigma…So technically, Six Sigma and DMAIC are separate tools…six sigma is about reducing variation to improve yield rate…DMAIC is like any other problem solid tool..PDCA, 8D, 7-Step, etc…does this help? If not, let me know.
@@learnkaizen again thank you.
So it is necessary to calculate the current six sigma level in this situation?
Is it okay if I write the thesis title as "Application of Six sigma DMAIC for productivity improvement" without calculating the sigma level?
I wouldn’t include six sigma in the title because technically you’re not using six sigma…an interesting research would be to utilize six sigma to understand the variation/fluctuation in raw material…that’s the underlying issue causing insufficient machine utilization. Even then, it’s a stretch but you could get the necessary numbers to complete the six sigma formula…this is where I’d focus my energy…if you use DMAIC, during the M(easure) phase, you’d measure the current state utilization…under analysis, you’d evaluate why..which leads to the variation in raw material delivery…then use six sigma to set controls on the material delivery with signals that escalate if delivery variation reaches exceeds parameters. This is just off the top of my head. You have way more knowledge on what you’re trying to accomplish. I don’t want to take you off course..these are just suggestions based on the limited information I have. Hope it helps and doesn’t confuse you…
Hi there. How come there are 6 sigmas to the left and only 3 to the right? Shouldn't it be 3 to each side?
My frustration comes form the squaring done at 7:35 in the video and maybe you can help me. We are forced to use a very basic calculator for the certification test. When you multiply .83*.83 you don't get .682 The calculator gives us .6889 What am I doing wrong? I am fixing to go insane here trying to figure that one issue out.
Oh man, sorry I missed this comment...apologies!!! I will take a look this weekend and get back to you with a comment...try to hang on until then! 😊
You're right. It looks like excel may have done something funky on the formula..don't stress - you're doing the arithmetic correctly.
@@learnkaizen Nice video - but I too became victim of this error
@@justrethinkllc no worries. I just appreciate your support!
fantastic explanation!! so much thanks
🙏
Thank you so much for explaining this concept with so much clarity.
I only wish you went further to explain how this can be used to improve the process and always make it within limits
That would’ve been a much longer video. Thanks for the comment!
@@learnkaizen Thank you for responding. Do you have one I can learn that from?
@@learnkaizen Also, how was 3.4 DPMO for six sigma arrived at? How was it calculated to get that?
I’ll answer this in an upcoming video if you don’t mind.
I have lots of DMAIC projects but I share them in my Root Cause Analysis course
Simply explained ! Thanks.
You’re welcome! Thank you for commenting!
Amazing explanation! Thank you very much for simplification of 6 Sigma cal.
Thank you! 🙏
