    Thanks everyone for the response.

    Actually my research is focussed towards IT and BPO.

    So can anyone guide me regarding the investments, ROI, % improvement and success rates/% in IT and/or BPO industry?

    Unfortunately getting concrete data and figures is getting difficult for me and I have to complete my research soon ans submit the findings, so any guidance towards the above questions would be great.

    Also if the person providing responses could also mention the Six Sigma project that he/she was involved in, like which process (eg loans, claims, some other IT project etc) was being revamped using Six Sigma, could be helpful to aunthenticate and back my findings.

    Regards,
    Student

    Thanks for the reply.

    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 projects and corresponding ROI?
    3. For such processes what could be the % of improvement?

    Thanks & Regards,
    Sujata

    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?

    Regards,
    Student

    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

    If you mean continuous, blood value MMA will be measured pre/blood value MMA will be measured post. ) Blood value B will be measured pre treatment then /Blood value B will be measured post treatment . Same value measured twice, but two different markers. (forgive my non statistical terms, only high school junior) All 30 subjects will be receiving the same substance.
    Then I would like to correlate the improvements in the 2 different markers in the blood to the behvioral assessment, which has a total score, but then will have a sub score measuring 4 different domains. The 4 subcatgories are:
    1. speech
    2. sociability
    3. sensory cognitive avareness
    4. Physical behavior
    Same questions pre test post test. Each sub category gives a numerical score, then all added for a total score.
     
    I don’t have the ability to do a placebo/double blind study with this population.
     
    Thank you for your help, and I hope this is more clearly explained.

    Yes 30 subjects measuring two lab values from pre/then post.So two values measured twice (start/end) Then a behvaioral assessment pre/then post(will be at the same time as the above values are obtained), the behavior  assessment measures 4 categories, but it will already be scored and a total then a subcore for each category. So a total score and 4 individual values pre and then again post on each 30 subjects.

    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 subject. I have mostly came across reviews on methodology and in general – sucess stories.
    I am asking for unbiased reseach. Thanks if you can help.

    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.

    all sixsigma people I’ve meet till now, are always happy, relaxed and proud. I’ve never meet sixsigma people stressed, or unhappy. for this reason everybody, and myself, want be sixsigma people.

    because ‘6’ is the only possible number to be used, because there are :  3C, 4D, 5S, 7S, 8D.

    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 score value (I don’t know which, but it is not important).
    you know your actual KPIs values, so you can compare it  (before and after change) with of changed process (from sample),  running a test on frequency using z-test or chi^2 test (number of questionnaries returned)  and/or test on means (on score value)  z-test two sample for means or T-test paired two sample for means.
    hope to be of some help. if not, apologies, if so, plese let me know.

    Very easy. Become supplier’s sixsigma consultant and deploy it. If supplier not improve, change supplier and get new contract as consultants.

    Hello Everyone,
    I want thank each one of you that was kind enough to post a reply to my question and especially to the one’s that have give their email addresses. I will call upon you time to time when I have exhauseted other avenues / option for any issue.
    Once again thanks a lot to everyone and also thanks to the person who tried using my screen name and tried to be funny. I hope his Six Sigma skills are better than his comedian skills.
    Thanks again!

    Mike,
    When I went to college, I took the feedback from the existing students. Thats what I am trying to do over here.
    Well I know there’s loads of material on this site and I have also started with the Six Sigma way. My Only concern is that these courses are very costly and lots of ppl try and make money over the net.
    You guys have done the research and can help me a lot. I don’t want you to do my homework, but atleast you can give me the know how.
    I am looking forward for the course material which has loads of case studies.
    Regards
    STUDENT
