  • Are you having a joke here. Why would you use SD on non-normal data?

  • I don’t see it like this and I may be wrong but standard deviation etc is about the shape of your data, height etc, where “6 Sigma as in the methodology” is about how much of that shape fits between your customer specifications.

    Yes I mean that you will get a lower standard deviation. But if you have more items in your customer specification your Sigma score will go up.
    The symbol for Standard deviation is Sigma this is not the sigma in “6 Sigma”. Is this what is confusing you?

    First. Thank you for the compliment if all you can pick fault with is sentence structure I take it you can’t fault the argument.
    Second. I din’t leave school early and got my qualification and titles etc. Which probably also proves my point.
    Third and not an excuse. Dyslexia……. If you can understand what I’ve said it’s a good day. At least…[Read more]

    Hi
    I think you may have 6 Sigma and control limits (+,- 3 Standard Deviations) mixed up.
    Your Sigma score is calculated by your customers requirements in your cases I guess the tolerance level they demand. There are two ways to improve your DPMO increase your tolerances (Not Good) or reduce variation so more items are produced within these…[Read more]

  • CT replied to the topic PhD or MBB? in the forum General 10 years, 6 months ago

    I never said education is overrated what I said that titles are overrated. Education and titles don’t have to be linked and in lots of cases aren’t especially when you add in application of knowledge.
    You can also read these pages to see how worthless the MBB title is and in lots of cases so are the PhD’s. With a wide level of variation on q…[Read more]

    Experience who cares about the letters after your name the only thing they tend to prove is your boredom level.
     

  • CT replied to the topic Idea Generation Question in the forum General 10 years, 6 months ago

    Thank you all for your input. There’s a few suggestions in there which I haven’t used before which look worth investigating.
    If there’s any others people can think of any techniques especially for when you have all the data you need, you know exactly what the problem is and why it happens but no one knows how to fix it. It doesn’t happen often b…[Read more]

  • Are the numbers leavers if so what is the size of the group they have come from?

  • CT replied to the topic Correlation in the forum General 10 years, 6 months ago

    Maybe worth tieing down what they mean by correlation?
    It can be used by some to be inter changable with the word relationship which is where the use of hypotheses testing may have come in. It’s not it’s true meaning but is often confused by people wanting to sound as they know what they’re talking about.

    It might be,
    What’s your data and what shape is it?

  • CT replied to the topic DPMO in the forum General 10 years, 6 months ago

    This is ok for internal focused measures but if your wanting a DPMO for your customer. Then have the opportunity of 1 and your defect is everytime you send them something with any error on it.
    This is what the customer feels so should be what you measure.

  • Is there no way of matching the error to the order?
    Also if there’s a lag can you have the error rate against the previous months figures. This is usually approx and depends on usage rate but I’ve seen it used to give an indication of issues.
    As a minor point are you looking at stock reduction as you seem to carry a lot of stock which you don’t…[Read more]

    1, Yes
    2, I would start at Green and work upwards, this is not for the belt but it should give you the level of training you’ll need to find out if you can do the roll or not. What you will need though is a Black belt mentor.

  • To reward teams bring in Pizza’s for lunch works well. Everyone feels good about being fed they get up and talk to each other.
    On individuals one of the rewards which gave the best feedback was half days or full days off.

  • CT replied to the topic Data Collection Plan in the forum General 10 years, 7 months ago

    I would include a reference to the DCP you’ll already have for the TAT information into your new one and then make sure it states how to link the two sets of data together.
    Saying that as long as you or anyone else can replicate the data collection from your documentation you can put it where you want.
    My 2p’s worth.

    When ever I’ve seen GB part of a bonus/promotion structure all that it’s engendered is people doing GB not to learn but to get a tick and projects being shoe horned into a structure which was not required making them last twice as long as required. All this leading to lots of GB but not much culture and in the end synasism.

  • From working at GE Money no it’s not a Six Sigma company in most cases they aimed high if they tried for 3.
    From a philosophy point of view they were also moving away from six sigma in dismantling the quality structures e.g QL, MBB, BB etc and pushing Lean as a quick fix solution but with no measures in place to see what they were doing to q…[Read more]

  • I work for a CRO, from pre-clinical onwards, and we’re implementing BPI and there are major areas where cost and money can be taken out of the process and we’re in the process of doing this. These varey from basic time/cost reduction, quality improvment projects to quicker better ways of running tests without degrading the results.

  • Yes.
    Need to create a core team with members from all the organisations. To keep numbers workable these will then probably have sub-project teams in each organisation. It can take more management than a standard project but nothing that can’t be worked around.
