Dear SJ, Thanks a lot for the clarity on the same. Sandeep

Hi, I want to understand the difference in usage or significance of both these charts apart from the fact that Range is involved in one of these and Sample SD is involved in the other How do we really decide: 1. When these charts should really be applicable/useful in practical scenario 2. Which of these should be preferred. Please share your views on the same.

Hi, I am a IT professional and from my experience and by looking at various case studies, it looks like Six Sigma tools like QFD, FMEA, Pareto Chart, Ishikawa diagram are the few important tools, which are mainly used across all six sigma initiatives in software industry I have not seen any case study in software industry, where advanced Six Sigma Tools like DOE or Regression analysis etc has been used or is really required.. Am I missing something here ? Is there any such example where advanced Six Sigma tools also come into focus. Most of the time, we have abundant data (incident log, failure log, duration log etc), which is analysed via Pareto and FMEA tools and finally Causal analysis is done and maybe this will conclude into some Process Guidelines or Automation as the end result. Please share your thoughts Thanks SG

Dear Suresh/Srini/Sripathy, Thanks a lot for all your inputs on the same... SG

Hi, I will like to understand : 1. How do we translate Process Capability into Sigma Level and vice-versa ? 2. What is the difference between Cpk and Ppk ?

Dear SJ, Thanks a lot for bringing the clarity on the same. Sandeep

Hi SJ, Thanks a lot for the clarity on the same in simple words. So that means 6 Sigma (3.4 dpmo ) in ST should be considered equivalent to 4.5 Sigma (Somewhere around 1350 dpmo) in LT When we say long term, is there any minimal period or timeframe, which we call as long term. Say more than 6 months is long term or it varies from industry to industry ? What are your thoughts on the same ? -Sandeep

What really is the concept behind 1.5 Sigma shift ? How do we determine whether the sigma level calculated is long term Sigma or Short term sigma level ?
