  Greetings from Singapore. Your videos are very educating! Thank you very much for producing and sharing it. Can I also take this opportunity to raise a query? I am confused with when should I use Sigma sample (n-1 for the denominator in the sqrt root), Sigma estimate (R-bar / D2 constant) or Sigma population (n for the denominator in the sqrt root). Could you help to clarify? Thanks!

  Thank you so much for your comment. Allow me to address your query. Sigma Population with denominator ‘n’ is used when we’ve data of the entire population (duh). Also, when we only want to quantify the variation in that particular set of data and we don’t want to extrapolate the data for predicting the process behavior. This is rarely a case with us engineers. Our goal is often to predict process behavior using a smaller sample. (Even if we collect data for an entire batch, it effectively represents a sample set of all parts produced or yet to be produced. I hope it makes sense). In sampling method, we use ‘n-1’ as denominator, so that the resulting value of standard deviation will become slightly higher and this ‘higher value’ is now our best guess for the value of standard deviation in the overall population. This is known as Bessel’s correction. (Now, you can ask me why n-1 and why not n-2 or n-3. To be honest, I do not know.) Finally, in my opinion, the R-bar/D2 method is a user-friendly way of calculating standard deviation, especially in Control Charts to spare operators from complex math during chart plotting. I hope it helps.🙂

  This analysis is wrong. You failed to consider the processing losses due to downtime, which amount to 48% at Op5. The critical operation, the operation that limits the throughput of the line is Op4 @a nominal 62 sec/pt. However, given the downtime losses, its net is 119 sec/pt., well below market demand/takt time of 100 secs. IF Op 4 is 100% labor, then doubling labor @Op4 may solve the problem. But, since it's assembly, some equipment is probably involved, meaning adding fixed assets/machinery, and upgrading QA to accommodate the extra throughput.

  Thank you for your comment, Steve. If you were referring to processing losses as Change Over losses, you’re absolutely correct. I intentionally omitted that aspect in this series, fearing that it would make things too complicated. However, I’m currently working on a separate series dedicated to reducing changeover time. It’s called SMED (Single-Minute Exchange of Die). You can find more information about it here. kzread.info/dash/bejne/anVmtsGDfaSWY7A.html Again, your comment brings me immense joy-it’s heartening to see people who question and seek beyond the status quo rather than merely accepting what’s taught to them.”

  I need one clarification, i have not seen Rbar/D2 in your sigma calculation for Cp. Please clarify

• 
  @think_lean3 ай бұрын

  Rbar / D2 is an easier way to estimate the value of Sigma (standard variation), where D2 is a function of n (sample size). I've deliberately skipped this formula since it may become pretty difficult to explain D2 which is a result of extremely difficult mathematical calculations. Just remember, as the sample size increases, the value of D2 increases and the value of standard deviation decreases for the same Rbar. That means with bigger sample size we can have better estimate of Standard Deviation. Coming back to your point, whether you calculate Sigma with Rbar/D2 or using the standard formula, your result will be the same. or most likely to be the same :)

  Refering to likelihood while explaining probability is kinda odd. Understanding these differences is crucial in statistical modeling and analysis, as it guides how one interprets data and makes inferences about models or future events. Probability applies to random events and is a forward-looking measure (predicting data given a model), while likelihood is a way of comparing different models or parameters based on observed data (assessing a model given the data).

• 
  @think_lean7 ай бұрын

  Dear mischapeters5204, thank you for your comment. And yes, technically you're correct. Probability → prediction (future) Likelihood → assessing (past/present) But will it be inappropriate to say that, "Probability measures the 'likelihood' of a future event based on available information."? Or can you help me find an alternate word (in place of likelihood) so that less experienced people who are new to SPC can also understand what I want to say 🙏.

• 
  @mischapeters52047 ай бұрын

  @@think_lean No, it is certainly not inappropriate, someone who is well versed in the definitions underlying probability and likelihood will understand what you mean. My point is more that you are trying to appeal to an audience that is less familiar with these terms and then you would do better to be strict. I think it would be better to say the following: Probability, in a broader sense, is the chance that something will happen, in this case, because it can also relate to the past.

  Think of Cp (Process Capability) as a measurement unit to identify if the process qualifies to make the product. If it doesn't, it's normally an engineer's job to 'IMPROVE' the process by modifying the machine, using different tools/dies or reducing the clearance between moving parts, etc. Once the Cp is qualified, then in the next step Cpk (the process index) is a measurement unit to identify if a process is set at the mean position. If it isn't, like the diameter is on the higher side or the length is on the lower side, then it's normally an operator's job to 'ADJUST' some machine's setting and bring it back to the mean position. Hope I'm able to answer; if you're asking something else, please elaborate a little. For example, what exactly is not clear? -Amit Gupta
