    I want training on six sigma yellow belt and also green belt.
     

  • Point Taken and well presented.

  • Shilps
    Let me set the background. You have prepared the set os questions and your customer is rating the questions in terms of ‘importance’ and ‘how are you performing’.
    The purpose of Csat is to know in which parameters you are exceeding the customer satisfaction and does it matter to the customer. So I would advice you to follow the below…[Read more]

  • Yadav replied to the topic Defect Prediction in the forum Software/IT 14 years, 8 months ago

    Hi Vignesh,
    Using regression model, you can come up with a equation that provides relation between the input variables and the output (defect rate).
    The input variables are the various factors that have significant impact on the output. These factors have to be verified using actual data and statistical tools like hypothesis testing methods or…[Read more]

    YES.

    Sidhartha,
    This can be a very good six sigma project and part from the root causes analysis, your primary focus should be on the measurement error of ‘visua verifier’.
    To get a quick grasp of the problem, you should be focussing on the VV process, to understand whether VV measurement process is capable to detect the kind of errors reported by…[Read more]

  • Yadav replied to the topic Uncontrolable IT in the forum Software/IT 14 years, 9 months ago

    The issues highlighted by you can be resolved or taken care of by scoping the project at the appropriate level and take buy-in from all the stakeholders.
    Typically before you kick-off the project, it is expected that you do the SIPOC, which will help you to scope the process based on the inputs and agencies, which will be focussed on, in your…[Read more]

  • Yadav replied to the topic Painting defect in the forum General 14 years, 9 months ago

    Aru,
    You can start with the data collection on the different defects and link each of the defect to the area of source. Then prepaare a pareto of the ‘area of source’ and prioritise the area of sources.
    Each area of source will have a process associated with it. Prepare  detail process map of the key ‘area of sources’ and then understand the…[Read more]

  • Hi,
    Six-Sigma compliments in acheiving CMMi maturity level.
    As you may be aware that in CMMi there are 22 process areas and each of the process area have best practices / guidelines/ standards which help you to improve that particular process area. DMAIC approach can be applied to improve each of the process area, which will help to acheive the…[Read more]

  • Yadav replied to the topic Six Sigma Weaknesses in the forum General 14 years, 9 months ago

    Hi Akash
    Ques: Are there any weaknesses to the Six Sigma methodology?
     Answer:  ‘No’, provided you apply it in the ‘right’ manner (use appropriate tools), for the right concerns (follow project selection criterias).
    Ques: Do any problems occur when you implement six sigma?
     Answer: ‘Yes’. Numerous problems and at various stages. In fact it is…[Read more]

  • Kisk,
    The process performance models for a software process have to take into consideration the functional domain and the technology used. Based on the complexity of the functional domain and the kind of technology used, the process performance model may differ, but the approach should not differ .
    Before you start building the model, you may…[Read more]

  • Lou,
    It is important that the metric you use for measurement of the process parameter, provides a correct perspective of the problem you are focussing on.
    In the example that you have quoted, the problem is the no. of troubled tickets in a specific category. You have mentioned that you have a sample of trouble tickets for 30 day period. Since…[Read more]

  • QP,
    As you may be aware Poisson distribution is used to model the number of events occuring in an interval of time.
    So it makes sense that you track the number of defect detected by your testing team and the defects leaked by the testing team for a fixed time interval.
    Hope this helps.

  • Hi Ravi,
    In my view, Six Sigma compliments CMMi. What course you want to do will depend on what skills you would like to leverage on, for your career growth.
    While CMMi is more focussed on Software industry, Six Sigma skills can be applied to any industry, provided you have the expertise in it. CMMi provides standards & guidelines for achieving…[Read more]

  • Yadav replied to the topic FMEA for service in the forum General 15 years ago

    Amisha,
    a. As  you know FMEA stands for Failure Mode Effect Analysis and one of the key output of FMEA is identify key failure modes, which have high severity and high rpn rating. The starting point of FMEA is the process mapping, which provides information on input paramters for each process step. Once you complete the FMEA for the process, you…[Read more]

  • Yadav replied to the topic Six Sigma and Textiles in the forum General 15 years, 2 months ago

    What do you want to discuss ? Can you specify what is your expectation from the six-sigma forum.
    Do you want to know how to start a six sigma project or do you want to know, whether this can be taken up as a six sigma project or do you want to know whether somebody else has done a similar project ? Can you clarify, so that answers will be more…[Read more]

    For information related to lean tools and methodlogies, you may visit the following website: http://www.lean.org.
    I am afraid that with the limited amount of information provided and the lack of exposure to what is actually ‘happening’ in your process, this forum can probably provide you pointers, which can help  you to ‘get…[Read more]

    Mike,
    You will find the answers provided in the previous messages helpful. I would like to add to that.
    Your 1st Question: Can over-production be considered a variation related project?
    My Answer: Depends on a few factors. Yes, under the following situation: -> If there is a lot of rework happening in your internal process, that means you are d…[Read more]
