Thematic Analysis
Qualitative Analysis usually takes a back seat while we work with numbers, however it is equally important. To be honest, I was not expecting that there will be such wonderful answers to this question (and I strongly recommend reading all answers). It was a difficult choice to make, however, I still had to make a choice. Answer from Rahul Arora has been selected as the winner for pointing out how Thematic Analysis can be utilized to understand the VOC to identify a potential project area.

Customer don't feel averages
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 in-house expert.

Sigma Level
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.

CATWOE Checklist
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)

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.
