    Hello RBK,
    Since you are in finance and accounts field, let me give you some quick examples of meaningful green belt project in your own space. Standard DMAIC methodology to be followed for green belt project. Google search will give you loads of training materials on DMAIC.

  • Hello Mike,
    A lot of global banks and investment banks are practicing Lean sixsigma for many years, in fact they are saving in millions. I would like to make three points here that may help you :
    1. Operation is the best place in financial services companies for lean sixsigma, for other departments it may prove to be a fad. I have myself…[Read more]

  • Hello Gregory,
    I would like to take part in this discussion as well. I am working for a large investment bank and heading the Lean sixsigma program. Would like to share my experience and learn from your experience on how to deploy LSS and what type of projects are generally applicable in investment banking space.
    It would be great if you could…[Read more]

  • Venkat,
    I suggest you look at the basic core definition of sigma instead of looking at at what DPMO level sigma start going negative, thats not the right approach.
    The basic definition of sigma level of a process is very statistical, it is :
    If you have single spec limit :
    ‘The number of standard deviation that a process can accomodate…[Read more]

  • Kris,
           As Gabriel rightly explained, there are two behavioral parameter of a process.
    1. Stability(caused by process variation or consistency issues and measured by control chart)
    2. Capability(response location with respect to the specification limits, caused by process centering issues or accuracy issues)
    Now the biggest questi…[Read more]

    Andy,
     yes I have implemented this method already. Can you please elaborate your question a bit further ?
    Regards.

  • Thanks,that really helps. As far as Minitab is concerned this is OK, but how much correct that histogram is with LSL at right of USL. If you would like to calculate Yield due to LSL(only), then do you take area at right or left ??

  • Mannu,
           I am late to reply. I understand what you are saying, but be more specific to my case. I have selected MTBF as Y measure. You can not break this any further. For such kind of a measure we have to wait for atleast one cycle(6 month) to prove the improvement. What you say ?

    Hi,
          Just trying to elaborate a bit more. We really cant say that with only DPU at hand we cant calculate process Sigma(Z). Yes we can if and only if both of the following conditions hold true :
    1. There are a considerable number of defect opportunities per unit.
    2. Defect opportunities are same for all Units in the sample. All your unit…[Read more]

  • Sathu,
        I do not think you got my  question. We need to improve the current application by reducing the frequency of outages. Generally for various reasons it goes down atleast once each month and this has been happening since last one year.
    This improvement opportunity has been taken up as a GB project with DMAIC rigor.
    Thx.
    Pallab.
