    >many of the comments I see here come from misinformed people who have not read or studied the Six Sigma methodology and think it’s just another “flavor of the month.” and then, for some reason, want everyone else to think they know all about SS.
    What does this have to do with my remarks? I thought we were talking about the name, not the value or…[Read more]

    RubberDude,
    For the record, my statistical knowledge pales in comparison to that of Stan and some of the other folks on here. I’m going to use a dirty word here, but I’d say I have more of an “intuitive” understanding of the implications of a concept, or how it can apply to a wide range of problems.
    Given the right tools, I can handle the…[Read more]

    >Statisticians will tell you that the six sigma level of performance is attainable and the best figure to work towards in any process – manufacturing or other.
    Is that so? What about the process of running a campaign for elective office? Or completing a pass in the NFL? Or the process of pitching a strike in baseball? What about a mass marketing…[Read more]

    Using this definition of arbitrary from Webster.com: “based on or determined by individual preference or convenience rather than by necessity or the intrinsic nature of something”
    Choosing to use the value six in Six Sigma may not have been arbitrary as in “arbitrary and capricious” but is was arbitrary in that it was convenient for Motorola at…[Read more]

    Mike,
    Your post touches on some of points which I would say support the claim that it’s arbitrary. As we get closer to 4, 5, and 6 sigma quality being more common in both manufacturing and transactional processes, the bar will rise.
    I’m not sure if the chart I’ve seen is the same as the one you’re referring to, but the one I’ve seen shows that e…[Read more]

  • KBailey replied to the topic Why it is called six sigma? in the forum General 17 years ago

    Stan, I didn’t suggest you were changing definitions. I just wanted to make sure 12 sigma might have some special meaning I wasn’t familiar with.
    I’m not disputing your statements about NASA or the apparent improbability of achieving a sigma level of 12. Practically speaking, I think it’s a bit unrealistic. However, if you had a process that’s…[Read more]

    RubberDude,
    Can you clarify which statements you take issue with and why?
    As for spelling and punctuation: I’m aware that many of the posters are from outside the US and UK. However, those of us from the US and UK also spell and punctuate our posts with a sigma level far below 6. Regardless of that, the point is that we don’t even try to achieve…[Read more]

  • KBailey replied to the topic Why it is called six sigma? in the forum General 17 years ago

    12 sigma is 2 * (6 sigma).
    Actually, you may have a fair question there, Stan.
    If you’re asking whether I know just how high of quality a sigma level of 12 would be and how much it would cost to attain it, the answer (in layman’s terms) is really good and a lot.
    If you’re suggesting that I didn’t answer the right question because sigma level…[Read more]

  • KBailey replied to the topic Why it is called six sigma? in the forum General 17 years ago

    The 6 in 6 Sigma is arbitrary. For most manufacturing processes, 3.4 defects per million is pretty darned good. If the cost of a defect is high enough, maybe 12 sigma is an appropriate goal – depending on the cost of achieving it.
    Obviously, we don’t strive very hard for 6 sigma in everything we do, including. For example, looking at iSixSigma…[Read more]

  • KBailey replied to the topic Mass production in the forum General 17 years ago

    I suggest using DPM or DPMO, depending on whether COPQ is driven more by number of defects or number of defectives.
    Bigger picture, it sounds like you may need to look at your changeover/setup process and the other things leading up to production, more than the actual production process. In mass production processes, quality is largely a matter…[Read more]

  • KBailey replied to the topic Six Sigma in statistical models in the forum General 17 years ago

    Yes, the concept of quality applies. The effectiveness of a marketing process can be measured by the number of customers who actually respond to the product campaign.
    There are still issues arising in the measurement and improvement. With marketing, you may be dealing with many significant factors outside your control, with significant…[Read more]

  • KBailey replied to the topic Warranty Cost Reduction in the forum General 17 years ago

    Rene, your situation reminds me of my experience with Microsoft and AOL. It’s never a defect in their product, the problem always must be on my end. I’m amazed at how often a problem they didn’t have goes away in their next update.
    I would add one thing to what Stan, Old, and the others have suggested:
    You may have a measurement systems probl…[Read more]

  • What are some key leadership outputs?

    High team productivity (quality and customer service are components of productivity)
    Optimal employee retention/turnover
    Hiring and developing employees for internal advancement
    Process improvement
    Cost and asset management
    Planning
    Most of these are actually easier to measure than some of the…[Read more]

  • I’m confused. You cannot measure productivity improvement initially, but you know the process is performing above the required target, and yet you know there’s an immediate need to improve productivity… it sounds like either you’re experiencing unplanned/poorly planned growth, or like someone decided they just needed to cut some heads.
    If…[Read more]

  • KBailey replied to the topic Process Sigma when Yield is 100% in the forum General 17 years ago

    Who actually sets the specifications? In my experience, the IT folks have set their own “specification” by guessing how long is the maximum it could possibly take them. It’s not the same as a customer specification.
    An appropriate analogy would be one of those situations on the Enterprise when Scotty (representing IT) would say he needed x but J…[Read more]

  • Sorry, Stan. I’m not taking the bait. I don’t need to prove anything to you. Considering the differences between people, no matter what I say you can dismiss it as incomplete/shallow/misleading, and call it a dumb response to a stupid question.
    The only soapbox I’m on is the one about whether you should try something before you give up on it,…[Read more]

  • NewBB, I picked up something in a project management class that may help.
    Draw out a little matrix with two scales, one for importance and one for urgency. Both scales can go low, medium, and high. Think of a few tasks and where they fit in the matrix. The normal tendency for most people is to spend a lot of time dealing with the urgent things,…[Read more]

  • Kim,
    Be careful with this one. Yes, it’s important to keep unscheduled absenteeism under control. However, the last thing you need is someone coming to work when they shouldn’t and getting everyone else sick. Not only can you create even more unscheduled absenteeism, but you’ll have sick, unproductive people making more mistakes than usual.
    A…[Read more]

  • In third-world countries in general, in your country, or in another specific country?
    Unless you’re in a very influential international leadership position, my suggestion is this: don’t set out to save the world.
    The best way I know to promote real SS is to apply the tools and discipline where you are. Be successful with it yourself. People who…[Read more]

  • Product & process change frequently, so measure training effectiveness for each product and process separately until you have enough understanding of how product and process factors affect the call center output. Examples: price, perishable vs durable.
    Also remember, training process is an improvement process, meaning that you need to compare…[Read more]
