    Unfortunately getting concrete data and figures is getting difficult for me and I have to complete my research soon ans submit the…[Read more]

    Can someone please guide me for the foll queries:

    For Six Sigma projects executed at BPOs and other back office processes like Loan Processing, Claims processing, etc.

    1. Generally, what % of Six Sigma projects are successful?
    2. What is the typical investment made on implementing Six Sigma principles for such…[Read more]

  • Thanks for the response.

    Another question: What % of Six Sigma projects are successful (generally, since it may not have a 100% success story)?

    Also can someone advise if there is any research paper relating to these topics in Six Sigma?


  • Thoughts from the iSixSigma Community are welcome:When has incoming inspection added value, in your
    experience? Guidelines for implementing an effective and efficient
    incoming inspection program?

  • Agree that the formula does not include the population figure; what i am looking at is a valid answer as to why sample size should not be dependent on population size. the answer to be explanatory for someone who does not understand statistics

  • So in other words, this would be considered a pilot study, and if the alpha value is p<0.05  one would state the studies limitations due to size of sample, but that it might be worth larger study? Is that correct?

  • Mike,
    THANKS! So far what I am getting is 0.01 so far so good. Phew! Three years on this and thought it would be no good. Would that p-value give my hypothesis more power? Even with such a low number of participants?

  • Thank you for explaining how to set it up. Knowing my sample size is small, but one more question, what would be a statistically strong p value for a study like this, I know many errors, but just wondering?
    Thanks again

  • THANK YOU! I have not read the articles yet but it is nice to have information on both sides of the track!

  • I understand that it is the “new” trend, but JIT and TQM were in the same place at one point and time. Now they seem to be replaced by Six Sigma. I like the Six Sigma strategy myself, but now as a grad student I am trying to search for good and bad “stories” for my thesis.  I am falling short on empirical research and literature reviews on the…[Read more]

    sixsigma, as every product, have its own lifetime and who care of that product lifecycle management, already know it from years. when a products is in its maturity stage, it can die or changed. for this reason sixsigma is now lean-sixsigma. now the point is to see if lean and ss work really well (better) togheter.

  • Sah replied to the topic Need help with testing methods in the forum General 15 years ago

    what you could do is : apply changes to your actual process as planned, for a defined sample of customer and check results with test. based on that, plan your hypothesis test.
    if you measure feedback through questionnaire, then you could have, at least, two KPIs : number or % of questionnaire received back (complete and/or incomplete) and a sco…[Read more]

  • Sah replied to the topic Need help with testing methods in the forum General 15 years ago

    test to be used depend by how do you measure customer feedback/satisfaction now. if you give more details, we can start to think about it togheter.
