    I have reached out to him and he sent me a powerPoint Deck of what thier group in Houston does as an overview.  But, being that I am in Sacramento, it is not cost effective to visit him.  As for VOC, in the hotel industry we try to listen to that daily and get some fantstic ideas from that.  I did forward your thoughts to our Corp office and hopefully they will listen to VOC, but I am at the hotel level and the scope of my position as a BB is to work on proving solution for my hotel.
    Thank you for your comments though.

    In regards to posting a question, i am looking to join or start a monthly group that meets to discuss process improvements that have been implemented.  My counterpart in Houston started one about 2 years ago, various BB’s and MBB’s that meet, discuss “pains” and brainstorm solutions.  They then work through the DMAIC process to make sure they found the right solution.
    As for the person who wrote about getting cheaper hotel room, what does that have to do with benchmarking?  If you are looking for less expensive hotel rooms, I recommend you check out Travelocity.

    Just tried this in Minitab and did not get what Stan is getting. Here is what I am doing can anyone provide some guidance.
    For X – Calc>Random Data>uniform>1000 trials>lower ep -0.01, upper ep 0.01. Store in C1 column
    For Y – Calc>Random Data>normal>1000 trials>mean = 0, std dev = 0.06. Store in C2 column
    use eqn SQRT(X^2+Y^2) and place in column C3.
    Use Calc>column statistics>select median>select C3 row for input variable and select ok and I get
    Median of EQN (Column C3) = 0.039353
    I am pretty sure I am on the right track here..any comments?

    I also just tried doing this in Minitab and got the same answer 0.0393526 for the median. Here is what I am doing..
    For X – Calc>random data> uniform> specify my lower and upper end points at -.01 and .01 and run 1000 trials.Column C1
    For Y –  Calc> random data > normal > specificy my mean as 0 and my std dev at .06 and run 100 trials. Column C2
    I calculated sqrt root sum of squares and that is column C3.
    I select Calc>column stats>select median.input variable is C3 and I get .039 approx for the median.
    Not sure why I am not getting a number close to Stans?

    I tried to do this in excel using a toolkit add in random number generator. I can generate random numbers for the uniform distribution but when I try to do it with the normal distribution the bounds I give mean of 0 and std dev of .06 the numbers generated are not all within the -.06 to .06 I would assume them to be. If someone has an excel sheet showing how to do this please let me know. Or drop me a line a [email protected]

    Wow guys…this is a bit embarassing. I guess I need to refresh my memory on simple partial derivatives. Thanks for the kick in the right direction. I would be interested to see in detail how you solved this in Minitab though. Meaning which functions you used.

    Is this relating to the effectiveness of anti-depressants survey and the so-called ‘expert’ on the BBC News this morning who said the paper was ‘ever so complicated’?  I have read the paper – http://medicine.plosjournals.org/perlserv/?request=get-document&doi=10.1371/journal.pmed.0050045 – no mention of mathematical modulation at all and it shouldn’t seem complicated to anyone with a reasonable grounding in statistics.

    If your green belts seem to be hesitating to take initiative to move the projects forward to completion, you might consider the impact of self-efficacy on performance. Self-efficacy is the confidence a person has that he or she can actually perform a task successfully. Research suggests that lack of self-efficacy usually results in performers who are reluctant to take action, because they fear making mistakes or feel they don’t really know what to do.
    This can happen when a training program doesn’t allow a learner to practice a skill or task (and get feedback) until he or she can perform competently. It may not be enough to describe a tool and give examples of its use. If the learner perceives the tool as complex or the task as risky, you may have to give them time to master the learning.
    Then you may be more likely to have green belts who will take initiative and drive projects to more rapid completion.

    I am also interested in this discussion. I have a situation where my perfect part is 0 and my upper spec limit is 13. My calculated lower control limit is something greater than zero but this is the perfect part. I am balancing a rotor so it is not possible to have a negitive weight and zero weight is perfect and 13 mg is the upper spec limit. The machine will try to balance anything greater than 13 but if a number of parts balance at 12 the machine is controlling the process but my charts say it is out of control. How do you handle something like this?

    For a little better understanding of this process:
    A spinning object such as a tire will normally be not balanced meaning that there is more weight in one area so that as it spins it will cause vibration. The perfect balance is to have no unequal weight or 0. A value of zero means that the weight is equally distributed and no weight needs to be added to achieve proper balance.
    In my case balance has been set as a specification by the customer with a range of 0 mg – 20 mg. I am using these values as my USL and LSL.

    Samsung passing Motorola, wow….I’m not suprised about Nokia’s strong sales and #1 spot however.
    Samsung has done an excellent job with their cell phones, the interface is freindly, etc.. Nokia has done the same. Motorola in contrast has been slipping. However, the new razor phone got a very good review in Cnet so maybe this phone will help moto. Part of the lower sales posted by moto may be that they were focusing on making phones for nextel instead of other big carriers like verizon wireless. Moto should be aggressively seeking contracts with verizon because verizon has the most market share; it just makes sense.

    This is rather arbitrary excersise from a lab.  It not a real experiment.I the 7.0 measurement was assumed to be take on another day.  So basically,  How confident can I be that this was merely due to chance, or not? What assumptions can I make and with what confidence can I conclude that something really did change in the measurement system.  this question has me very confused…

    Hi Bill,
    I am very interested in knowing ways and methods in chosing projects especially for green belts (not just for certification purpose).  The matrix that you mentioned in your email would help a lot.  If possible, could you help out here?

    There are people in India, China, and all over Asia Pacific conducting Green and Black Belt, so cost does not appear to be and obstacle for them.

    Is it unreasonable to pay $20k to receive an annual return of >$200k? Seems like a fairly easy decision to me.

    We spend a significant amount of time on subgrouping (half day?), teaching the natural progression of time plot -> I-mR -> xbar-R.

    I agree that Air Academy (and most others, to be fair) do not teach it.

    Seems only those with ties to the original Honeywell/Allied program really get it / teach it.

    I also agree that it is critical, and often tragically abused because people have no clue what question they are asking when they construct the chart.

    (Same thing for COV)

    If you want a company that recognizes your personal worth and not certificates, then why did you waste all your time getting all those other certifications? Why did you bother collecting your Masters when you could have just done the courses and not bothered to pick up your diploma?

    It may be that you are unhappy that the vast pile of certifications you have don’t align with the certifications that the companies are looking for. That’s life – move with the changes, or moan about how people should value the hard work you’ve done in the past. Companies want evidence that you have delivered tangible business benefits throught the application of DMAIC (or MAIC, or whatever).

    I can’t tell you how many people I’ve run across that say “I’ve been doing this for years, I shouldn’t have to go through the training” – and they are the ones who end up gaining the most.

    Give it a try, at worst you might learn something.

    I recommend the Air Academy statapults. They are pricey (~$175/ea for 5), but they hold up really well to the rigors of training.

    There is no reliable certification body. A number of companies / organizations are attempting to evolve into that role.

    I interview a lot of Black Belt / Master Black Belts, and IMHO certification is not an indicator of quality. The only way to assess competency is by asking the right questions.

    Injection molding is a great place for six sigma. We have done a number of projects there – especially useful when you are struggling to qualify all the cavities of a multi-cavity mold.

    Injection molding is all driven by multiple-factor interaction. It’s a DOE playground.

    It’s not clear to me that counting opportunities really does anything to improve processes. Last time I checked, you have to go out and do improvement projects to make things better. IMHO, some companies place far too much importance on counting opportunities when they should be getting work done instead.

    I advise against counting opportunities.

    First, I think if you look you’ll find plenty of people doing Black Belt in India.

    Second, effective Black Belt can’t be taught reomotely or online (or at least I haven’t seen it). It also can’t be taught in less than 4 weeks. There is a lot more to Black Belt than justing going through the material, it’s the practical application of the problem solving methodology in a team environment, and if you don’t get experience with that in the training, it’s not Black Belt training.

    No offense, but I really hope that the answer is no (though I suspect someone will do it). The ‘courses’ that have an instructor at the front of the room rapidly flipping through an enormous array of powerpoint slides are, in my opinion, a complete and utter waste of time.

    How do you plan on learning how to teach this stuff if you just get a copy of the course material? The best instructors I’ve seen teach from no material, they just do it all on the flipcharts anyway.

    In general, engineering salaries seem to be lower in the UK than in the US, so if you can work in the US and are willing, it seems likely that you could pull a higher salary.

    Yellow Belt is not a very widely recognized term. It seemed to have a brief spurt of popularity several years ago, but doesn’t seem to be very popular any more.

    Basically, it is intended to be awareness/overview training, generally targeted at hourly/admin employees. The term is confusing because a ‘Belt’ is usually assumed to have some ability to go out into the organization and successfully complete projects, but a ‘Yellow Belt’ has no such skill.

    I’d advise against using the term, and just do awareness/overview training (4-8 hours).

    We’re focusing on 2 areas initially:

    1. Market Research. There’s a lot of processes, DOEs, MSEs, etc. And knowledge of maths.

    2. Forecasting. Crosses over into Ops/Logistics, where there is already strong six sigma presence.

    My advice would be to find the right places in the organization to start, and build the internal-to-sales&marketing success stories there. Then use that to build six sigma out into the rest of the group.

    I’m not sure I would regard six sigma academy as the benchmark for certification…

    Generally, you look for completion of the course of study, documented application of the tools and thought process, and tangible business benefits.

    This should probably be treated as more of a lean project than a variation reduction project. The root of forecast error tends to be the lead times required and the inherent vulnerability of any predictive model of a system with many inputs dependent on human guessing/estimates.

    I would focus on moving to a demand based system (you probably won’t get there, but it should be how you are thinking).

    Well, it may be that those comments are a little unpolitically-correct, but I find myself in general agreement. Let the buyer beware is good advice when shopping for the right consultants to partner with for implementation.
