Mayank Gupta started following Sigma Level , Customer don't feel averages and Lean Accounting

Customer don't feel averages
Mayank Gupta replied to Vishwadeep Khatri's question in We ask and you answer! The best answer wins.
The intent of the question was to highlight the fact that customers do not feel the average or the mean. They always feel the variation or difference in the service. While there were many responses to the question, few of them could not be approved as they were not relevant to the context. The best answer has been provided by P Balakumaaran. Also review the answer provided by Mr Venugopal R, Benchmark Six Sigma's inhouse expert. 5 replies

Lean Accounting
Mayank Gupta replied to Vishwadeep Khatri's question in We ask and you answer! The best answer wins.
Lean Accounting can help an organization quantify their improvement efforts. This fact has been highlighted by the example quoted by Anshul Vaidya. Hence his answer has been selected as the best!! There are a couple of more answers that compare the traditional accounting with lean accounting statement. These are also a good read. 
Sigma Level
Mayank Gupta replied to Vishwadeep Khatri's question in We ask and you answer! The best answer wins.
This seemingly simple question has proved to be very challenging. The statement  "Sigma Level for a process cannot be calculated if there are zero defects"  is only true for Discrete Data. This statement does not hold good for Continuous Data. For Continuous Data, Sigma Level can be calculated (without knowing the actual defect count) and it indicates the probability of getting defects (DPMO). For Discrete Data, we first calculate DPMO / DPU / Yield% (with the actual defect count) and then convert them to Sigma Level. Hence, if defects are 0, there is no Sigma Level for Discrete Data. While there are a few answers which seemed to be moving in the right direction, however no answer is completely correct. Hence, there are no winners for this question. 7 replies

CATWOE Checklist
Mayank Gupta replied to Vishwadeep Khatri's question in We ask and you answer! The best answer wins.
Very detailed answers from all respondents. Anshul has provided the best answer to the question. My view  CATWOE checklist is better suited to identify and understand the problem. Once done, it can then help the team visualize multiple potential solutions. However these are potential solutions  they still need to be evaluated and optimized. (my view has no bearing on the selection of the best answer) 
Reliability Block Diagram
Mayank Gupta replied to Vishwadeep Khatri's question in We ask and you answer! The best answer wins.
While all answers are well drafted, there are two that stand out  P Balakumaaran and Manish Manjhi. Both answers are a must read and both answers are selected as winners. P Balakumaaran  answer for its simple yet powerful way of explaining RBD plus its usage. Manish Manjhi  for highlighting its valid usage across 4 phases of DMADV. Congratulations to both!! 5 replies

Correlation vs Covariance
Mayank Gupta replied to Vishwadeep Khatri's question in We ask and you answer! The best answer wins.
This was a tricky question to answer. In the published answers there are two distinct approaches  one more conceptual and theoretical while the other involves explaining with an example. While Anshul's answer is a treatise on the question and is a must read, Mohamed's answer scores a bit more for the example. Hence, Mohamed's answer has been selected as the winner. 
Screening Design
