I thought this one is particularly hard and I must say, I am delighted by the top responses. The three selected answers are by Venugopal R, Mohan PB, and Raghavendra Rao. Study of process potential in my view is the most valid situation where variation rules supreme. Venu has highlighted ANOVA, Relative grading systems, Control Chart logic in general and Temp variation in a mould, and impact of voltage fluctuation on electric appliances in specific. All these are well thought and presented. He has also highlighted situations where controlled variation is favourable and where variation is favourable. Mohan has presented very strong and valid situations as well. He has highlighted relative ease of target and a few others. Mohan’s specific example of batch processing was a brilliant piece. Raghavendra Rao has stated specific scenarios accurately – unpredictable process, influence of special causes, skewness of data. A few examples would have brought his response few notches up. While there are several other noteworthy responses too, in my view these three as the better ones and the one by Venugopal R as the best.

One industry sector that is booming globally is Business Analytics. One way to understand this domain is to divide in three parts - Descriptive Analytics (What has happened), Predictive Analytics (Understanding the future), and Prescriptive Analytics (Decision making to influence business outcomes). There are Analytics experts who do not link well with business excellence and there are business excellence professionals who do not know much about the vast and expanding domain of Analytics. Benchmark Six Sigma is about to launch Business Analytics courses in January 2018 to address this. Which among the three Business Analytics areas (Descriptive, Predictive and Prescriptive) are captured by the Lean Six Sigma community reasonably well and which areas still seem largely unexplored?
