• Dear Charmed,
    Answers to your questions,
    1. DPMO is representative of capability as sigma is, the reason I mentioned it because it was part of JJ’s question.
    2. 1.5 explains shift which difference in long term and short term capability, calculated over period of time and established emperically (Motorola was involved in the study). It is added…[Read more]

  • Dear JJ,
    As everyone has said you need to know number of opportunity per unit before you calculate DPMO.
    Still you can take down the formula to calculate it,
    DPMO=(defects/opprtunities) * 1000000
    defect = total defects in defective units
    opportunities = total unit * number of opportunity per unit
    For sigma calculation you can use following…[Read more]

    Hi Mike,
    Question for you.
    Wouldn’t the indirect cost also include the opportunity cost of money which is being received late by the manufacturer due to late delivery and so late billing. Given the large amounts involved I am sure it poses a threat to cash flows.

    Dear Charmed,
    I do like your comment “Don’t try to raise the bar, or revise anything, proactively. Do so if and only if it will help you get an edge on the competition”
    I was trying to say the same thing though I took a different approach. Assuming there is a hugh cost or effort involved in raising the bar, clients buy in is very import…[Read more]

  • John can you give an example when one would not be able to validate the relationship.

    Dear Kiruba,
    Thanks for asking this question!
    This is a classic case when the client’s defined target are easily met at the call centre, but from end customer perspective it looks like the service provided is not as rosy as it looks on the dashboard.
    And if you raise this question to the client, depending on if it third party or captive…[Read more]

  • Dear Jimgggg,
    This should suffice. For all those who like solving puzzles.
    This is tougher problem than the ones which say if one of the weights is lighter or heavier. The solution is long, I could not find any other alternative solution. So here I go.
    Select any eight ball and label them from 1 to 8 and put four of them on each side of the…[Read more]

  • Dear peppe,
    I thing following steps would make sense,

    First Study Interactions between three metrices:

    Speak to subject matter expert and find out if logically they could be inrelated. If yes,
    Use correlation.
    If the correlation comes significant you could use multivariate charts to monitor them over time
    If there is no interaction, use…[Read more]

    Dear Mike Xie Fang,
    Ever thought of about India? India is fast emerging as acceptor of six sigma in service and manufacturing industry and the infrastructure has gotten strong after few companies like GE, Wipro, Infosys have talking about benefits from six sigma.
    Training could be provided over here in India or at China depending on the r…[Read more]

  • I am sure DOE is not the tool which can be used (as you wont be able to control the deviation so you can not design experiment)
    But before I go forward, would you be able to clarify what are you trying to do, and what kind of analysis you wish to do. (i understand till, that you wish to report the metrices monthly but not clear after that)

  • Hi Alvaro,
    I think Kirk has pretty much answered you question. Just to add to it, create a project templates which work as a guide to follow six sigma methodology, also create a check list for tollgates based on the methodology which can be used to give signoffs. (Do let me know if you need sample checklist)

  • Hi Sgoel,
    Two sides of a coin:
    From project point of view, it is complete when metric is improved, improvements sustained (as correctly mentioned by Nayak), and sign off on benefits from finance team(afterall $$ is important!).
    From project manager or BB point of view, I would definitely focus on the my deliverables when in define. The champion…[Read more]

  • Hi PharmaBB,
    Following link has some case studies on lean.
    I think lean tools should help.

  • Hi Laxmanan,
    Thanks for your inputs. The answer to your question is:
    Yes it does assume that the graph for each passes through the origin. If you take the percentage deviation than at target the vector would look like (0,0,0) and so when at target you have no deviation.(your point would have been correct if we would have taken the data as it is,…[Read more]

  • Hi Pepe,
    I am trying to use the vector algebra to devise a method.
    Suppose the three process are x,y and z and the values for one product for the process is a, b and c resp..
    than the vector(data point) can be defined as
    and the value of vector can be defined as
    if your target is defined as

  • Hi Zack,
    Would you be able to send copy of C&E to me also at [email protected]

  • Hi Maharajan,
    I have gone through the case and seen the pictures also. I also tried playing with the data. Few things I could make out:
    1. Measurement System: If you could mark the sample before first check point(may be colour stickers). Than to collect data, you just need to count number of items with colour stickers at each check point.
    2.…[Read more]

  • Hi Praveen,
    The four basic charts used with attribute data are:
    c Chart: with defect data, constant sample size
    u Chart: with defect data, variable sample size
    np Chart: with defective data, constant sample size
    p Chart: with defective data, variable sample size
    Once you figure out what kind of data you have(defect or defective) it is not d…[Read more]
