    Bill,You can get a rough idea who is who by seeing which regular posters disappear during these threads.Not that it really matters. What matters is that ‘we ain’t seen nothing yet’,but the forum still persists in trying to find out who can p**s further than anyone else.Does anyone have a pension left?

    Thank you all for your responses to my question.
    I realize that it was vague, and (maybe) mixing apples and oranges, but I was so dumbfounded by the explanation I was given that I needed to get it out of my system.
    I also realize that going to a Six Sigma page, and asking if Six Sigma is good is like going to Vegas and asking if gambling is a healthy habit…
    Regardless, I appreciate your time in expressing your opinions.

    Alex, thanks for the feedback.  This is all new to me.  I just started a class in 6sig and its a bit confusing.  Do you have any material I can reference?  These are the areas I am stuck on: 
    process Map – Supplier(self), inputs (information???), Process(sales pitch), output (sales contract), customers (peole I call on)
    definition of CTQ (I defined it as -delivering quality sale call which keep customer buying product) service- vs CTB (delivering compelling message and closing the customer) :  sounds right?
    measure performance- how many months should I look at.  Currently selected one month and looked at 50 call in that month and whether they were successful or not.  I took the average of successful calls.  If not successful I wrote down the reasons why.  then I put reason a pareto chart.  Broke down each reason into fishbone diagram.
    That’s as far as I got. …
    should I add more than one month so I can set up a distrbution and stdv or is there another way I can look at those 50 call?
    thanks for your feedback!

    I am trying to increase sales.  The measure I am using is was the sales call successful?  I am trying to inprove the ratio of visit made customers to successful sale.  any suggestions?  One of the other things I am looking at is the factors that contributed to an unsuccessful sale.  ex:  could not see customer, poor sales pitch etc..

    An employer has the right to check on your education background. Just like an employer can verify your criminal and educational background, they can also find out about your training. Any employer can use a third party to verify somebody’s background.
    My opinion is that there should be a central database for all certified trainees that employers can access and find out if someone has been certified in Six Sigma, or PMP.

    You should check with the institution that gave him the certification. For instance, I got my Six Sigma Green Belt through University of Illinois; one can call and verify if and when I was trained. All institution should have a record locator for all people trained, just like colleges do.

    A scenario might be 2 stamping machines performing differently from one another.  You may have consistency within each machine, but not between them.  Your limits on the x-bar chart may be tight (due to the consistency of each machine) but the averages may all fall outside of the control limits.  The number one thing to remember in control charts is “Do not group unlike data on the same control chart”. 
    Why are you using the x-bar/S instead of the x-bar/R? Once you answer that, I can respond with, “Why do you have subgroups greater than 10?”  and “Why don’t you collect smaller subgroup sizes, (more frequently, if necessary)?

    Robino,This my 3rd attempt at responding. You do not have sufficient evidence to reject the null for a couple of reasons:1) Your “noise” is too great. The noise is the denominator in the test statistic (in this case, “Z”). The noise is a function of the hypothesized p (what your are testing against) The as your hypothesized p approaches p .5, the denominator will be larger, creating more “noise”. As n is small, the denominator will be larger, again crating more “noise”.
    2) Your “signal” is too small. The signal is difference between your observed proportion, and your hypothesized p. The greater the difference, the stronger the signal.
    3) Finally, there really is no difference.The test statistic (Z value) is really a signal to noise ratio. The stronger the signal, and weaker the noise, the higher the value of Z, and subsequently the smaller the value of p.You could also relax your criteria for rejecting the null hypothesis. For exploratory data analysis, an alpha value of .10, rather than .05 is acceptable. If your p-value is greater than .05 but less than .05, you could reject the null hypothesis. The risk is you have a slightly greater chance of rejecting the null when you should not.

    My quick response is we don’t use p-values to assess the stability of a process, we use control charts to help distinguish random from non-random variation..05 is a default value, but you should not be “blinded” by it. It is completely appropriate to change that to .10 or .01 in some cases. It helps you assess risk of over reacting (rejecting the null when you shouldn’t have).Span (Range, Standard deviation, Variance and Sum of Squares) are all ways to describe variability in the data (process).

    Another thought is to try to identify organizations that have embraced Six Sigma (another touch challenge) and than use the estimate of around 2% Black Belt certified. That will is a very rough estimate, because of the constant churn of Black Belts.

    Stan,Thanks again for your response. I respect what you are saying regarding the instructor/class relationship. I do believe that ratio would work, but so many other factors have to be of high quality. There must be an appropriate sized class room, proper layout of the room, high quality training materials, and students should arrive with project areas already in mind. If those elements were in place, then the instructor can focus on successful delivery.

    Stan,Thanks for the response. I meant no disrespect to Montgomery. I reference his DOE book often. One of my first SPC texts was also Grant & Leavenworth. I whole-heartedly support Crosby’s idea that “Quality is Free”. If Six Sigma waves are not more than paying for themselves, something is wrong. Yes. You are spot with your regard to action on the control charts. That is why Deming believed SPC began with management, not with people on the shop floor. SPC is discipline and most people still accept in spec is good, out of spec is bad. They don’t understand that processes that are stable, may occasionally produce non-conforming product or service, if there is excessive variation. Most management still wants answers and changes for the out of spec occurrence. Until processes are understood, causal factors are understood, and ultimately variation is understood, they will repeat that questioning over and over again, to no avail. It will be frustrating cycle.
    Thanks for sharing your opinion.

    To be fair, I should add that just as I believe your comments can apply to organizations other than GEHC, not all my comments extend to all six sigma deployments.
    As has been tossed around before, a standard would be helpful. I only know of a few people still around (Mike C.) who still aren’t afraid to walk out the door, if clients don’t want to stick with the rigor.
    The fortunate people are those who benefited from the original deployments at Motorola, Allied, GE, Caterpillar.

    Hunter,Again your comments are on the mark, but I don’t believe limited to GEHC. I left Six Sigma consulting because I lost faith in how it was being approached across the board. The model when I began consulting (1996, GE) was:
    1) BB training was 4 weeks of classroom training over 4 months
    2) When Lean Master training began it was 4 weeks of classroom training over 4 months
    3) We had 2 instructors
    4) About 20 people in class
    5) Proven training material
    6) Intense project coaching during the training and the weeks between the classroom training
    7) Project Champion & executive coaching
    7) Rigorous tollgate reviews.
    Which has involved into:
    1) 4 weeks for combined Lean & BB training,
    2) 1 instructor
    3) More than 20 people in a class
    4) Training material that changes (not improves) every wave
    5) Minimal coaching (where the real learning occurs)
    6) Minimal coaching for Project Champions
    7) Ineffective tollgates.I no longer felt like we were setting BBs up for success, so I’ve moved on. It was always, “clients don’t want to pay”. My previous experience was that with the original model, you would always have at least one project that would more than pay for the entire Six Sigma wave! We were no longer focusing on that, and instead focusing on training.

    C,…Hamids original inquiry into the central limit theorem. My bias is evident, as I was trained by Dr. Wheeler (spcpress.com). I still go back to the practicality of the I-mR chart. When non-normal data is evident, then it is better to modify the rules for interpretation, than attempt elegant transformations to normality. Variables charts for sub-grouped data (x-bar, R, & x-bar, S). Should not non-normal too often. Remember this a bout process, not mathematical models. Shewhart came up with a pretty powerful technique that workers on the shop floor could understand and you can imagine what version of Minitab that was! :)

    There is no assumption of normality for the control chart. There is no assumption of normality for the control chart. The 3 sigma limits work for the normal, uniform, right triangular, Burr, Chi-Square and exponential. Minitab cites Wheeler & Chambers when advising people of the Box-Cox transformation. “The Box-Cox transformation can be useful for correcting both nonnormality in process data and subgroup process variation that is related to the subgroup mean. Under most conditions, it is not necessary to correct for nonnormality unless the data are highly skewed. Wheeler [33] and Wheeler and Chambers [32] suggest that it is not necessary to transform data that are used in control charts, because control charts work well in situations where data are not normally distributed. They give an excellent demonstration of the performance of control charts when data are collected from a variety of nonsymmetric distributions.”Ranges will not be normally distributed, so the assumption is blown right away.Douglas Montomery? I believe he also lists A2 factors for n=2…n=6 as “0”. It is not “0”. The factor is N/A as the complete calculation is negative.

    I agree going to the customer is what you would like to do, but asking them is not always effective. Customers really don’t have a good sense of time. They may “say” 15 minutes is tolerable, but they just pulled that number out of a hat, so to speak. A better way might be to question them after service has been provided. You will have to capture their wait time, and compare that to the level of satisfaction for the wait time. You should obviously see greater satisfaction for the the wait time when it is short and the decline when longer, and you can then determine what an appropriate wait time might be.

    What is the purpose of transforming the data? If it is to determine process capability and you have at least five good and at least five bad, then just determine the percentage good and you have the yield.
    If you must transform the data because you have less then five good and five bad, then whatever lambda value you use for the original data, must also be used for the spec limit(s). In your example, you chose lambda = .5 (square root) so you would also have to take the square root of the spec limit(s).

    I used to save many clips on a flash drive, but now you can find most on YouTube. Lucy on the chocolate candy line is a classic one. “FOX sports play-off commercial” is another great one for assembly issues.
    Of course, the “careerbuilder monkeys” and “trunk monkeys” are old favorites, although tougher to make the links to projects (brainstorming solutions perhaps)
    Monty Python clips are easy to find as well. “She’s a witch” is a classic for root cause analysis & “Bridge of Death” is great for tollgate reviews.
    These have been circulated through so many waves of training, they are fairly common. I was concerned because one client liked the videos so much, they wanted it standardized into the training material! I asked to get the copyright permission and we would do it!

    It seems this thread is now deviating (no pun intended) to control charts instead of the central limit theorem.
    When addressing OC curves, alpha & beta risk, area under the curve & central limit theorem, it appears there is a fundamental misunderstanding between analytical studies (SPC) and enumerative studies (hypothesis testing).I think you will find the following article very useful.

    Tamlyn,
    Your observation (and sarcam) is on the mark.  There should be an additonal forum for those just interested in bashing one another.  When I direct students to this site I sadly advise them the discussion forum should be reviewed primarily for entertainment.
    While I would never hire anyone just because they are ASQ certified, it does demonstrate they are interested in networking with other quality professionals and taken steps towards professional recognition.   As many have noted, any certification should be a starting point in the hiring process.  As “The Hunter” noted, the real discoveries will be in the interview process.

    If you have Minitab, Minitab also has a macro that demonstrates this:
    ” Demonstration of the Central Limit Theorem
    Provides a “guided tour” of the Central Limit Theorem, simulating multiple throws of a die to demonstrate the theorem. Concepts are explained in notes in the Session window, and graphs show the results of simulations. The theorem states that if random samples of size n are repeatedly drawn from a population with a finite mean, mu(y), and standard deviation, sigma(y), then when n is large, the distribution of the sample means will be approximately normal with mean equal to mu(y), and standard deviation equal to (sigma(y))/sqrt(n).”

    I am confident that if you dictated that the awarding of a LSS contract was dictated upon a provider’s ability to guarantee trained BB’s pass the ASQ CSSBB exam and financial (audit ready) project results, they would guarantee. Now what separates the leading providers from the posers, is the leading providers would dictate many stipulations, prior to guaranteeing.

    It is a sad observation. Even sadder, is that those observations are probably not limited to GE Health Care.
    If you follow any of the discussion forums, on this site, you quickly discover people miss the whole concept. People confuse Pareto charts for histograms, scatter plots for time series graphs. They also jump into hypothesis testing when it is not necessary. They got blinded by p-values! They blindly interpret relative to .05, but can’t tell you the consequences of rejecting at .06. It is not their fault. It is the fault of the group that is certifying these individuals.

    Its not a guarantee of success but if you come across an organization that is certified by IACET (http://www.iacet.org/)and awards continuing education units (CEUs), you know that at least the material has defined objectives and testing to ensure successful delivery.
    It is a shame that the awarding of CEU’s after 160 hours of training is not mandatory.

The smaller the p-value, the smaller the probability that rejecting the null hypothesis is a mistake. Before conducting any analysis, determine your alpha (a) level. A commonly used value is 0.05. If the p-value of a test statistic is less than your alpha, you reject the null hypothesis.

The benefit is 3-fold.
    1) They knew what I told them was correct
    2) They understand all the info that is available in the help menu
    3) They don’t call me or e-mail me with those types of questions later!Another hint is to choose Help after choosing the tool you are interested in. For this example,
    Stat>Control Charts>Variables Charts for Subgroups>X-bar-S>Help>See Also (top right of help page>Methods & Formulas>Methods>Methods for Estimating Standard Deviation
    It narrows down the search area for the questions you have

    Through this discussion thread, people might learn the advantage of a pull vs push system! I might include this discussion thread of an example of a non-lean approach!

    I agree with Stan. While there are the “generic” categories of people, methods, machines, materials, measurement, and environment, often the free-form brainstorming can generate more causes without those restrictions.
    A couple key suggestions. Make sure the “head of the fish” is a FOCUSED problem statement. If it is too broad, the fishbone can quickly become overwhelming. Make sure the root causes are driven down to ACTIONABLE levels. When asked “Why does the number of automobile accidents increase in Colorado in the winter time”, and the response is “the snow”, that is not helpful. If the response is “cars slide in the snow”, then then next level is easy, “People did not have proper snow tires”, or “the roads were not adequately prepared”, or “drivers do not allow enough braking distance” and so forth. We can’t keep it from snowing, but we can try and deal with it, when it does snow! Finally, do attempt to do fishbone on flipchart paper. It seems as soon as people run out room, they run out of ideas. The bigger the wall space, the more potential causes are generated.Also know that most people are aware of Ishikawa’s “cause enumeration” approach to causal analysis, but he also talked about “dispersion analysis” and “process classification” causal analysis, among others. There is a reason that ASQ awards an annual medal in his honor. He was a fascinating man, who really believed in the team approach to problem solving. Good luck!PS The fishbone is my favorite, of the seven basic quality tools.

    Dr Scott,Now he is averaging his averages. What is his criteria for choosing 10 as a subgroup size? The 10 averages that will be subgrouped have nothing to do with the original 10 individual values that were averaged.

    Brandon,You addressed the primary reason I sat for SSBB exam. ASQ has been around the longest and if any organization should oversee efforts towards standardization, they should.The lack of standardization has got so bad I referred to belts as “prism belts” – they change color based on how much light was shined on them.

    Brandon,Nicely said. You are correct, for some the memberships/certifications mean little. For others they use if for networking and professional recognition and they place more value on it.
    It will be interesting to see if there is a fee increase based on the results of the survey.
    I was much more proud of my CQE designation than the SSBB designation. Pete

    I feel pretty comfortable that my ASQ membership is worth much more than the membership fee, and any certifications are worth more than the application fee and the time to prep and sit for the exam.

    I really don’t find those numbers that difficult to believe. When I transitioned out the military in 1997, it was my ASQ CQE designation that enabled me to have a very smooth transition out of the military into the GE’s Six Sigma world.

    Do you know if there is any effort to managing to the target rather than to the spec? As Deming said, “Specifications are the starting point, not the ending point”.

    First of all, congratulations on all your accreditations! ASQ has a specific Navy Six Sigma Belt certification. Will you have the opportunity to sit for that certification? I agree with QualityColorado (not just because I am also from CO), the real sell is during the interview. Some HR recruiters will not even get you in the door with out a 4 year degree, but that will be their loss.

    William, If you access the search function (upper right) on this site, and enter “call center” you will find many fine articles on call centers and Six Sigma.
    Long ago, when I was implementing Process Management and Control Systems in a financial services customer support center, I found the incoming.com site very helpful. Back then most of the information was free, now it charges you for most downloads.

    I agree. It really is pretty simple. I get concerned when we feel it is necessary to “dumb-it down”. The team members might hurt for a little as learning is occurring but that’s not a bad thing.

    I concur with Alastair. I would rather the team try and understand the logic of the higher number for the lower detectability.

    Also be advised that older versions of Minitab (not MTB 15) and some other SPC packages will adjust standard deviation overall by the the bias correction factor “c4” which lead to a slightly different statement of overall standard deviation in Minitab’s Graphical Summary and the standard deviation calculation in the Capability Analysis. Some users would be puzzled by why the two standard deviations were not exactly the same.

    My bad. I was multi-tasking during the response and addressed the wrong scale. For your team you could just ask the to determine the detectability from the following scale:
    10. Defect Undetectable
    9. Units sporadically checked for defects
    8. Units systematically sampled and inspected
    7. All units manually inspected
    6. Mistake-proofing modifications after inspection
    5. SPC and manual inspection
    4. SPC w/immediate reaction to out-of-control
    conditions
    3. SPC w/100% inspection surrounding out-of-control
    conditions
    2. 100% automatic inspections
    1. Defect is obvious and can be kept from reaching
    customer.Let them agree to characteristic on the right and do not even show them the number associated with it. Let them review the RPN when you are done, and it should make sense to them.

    If the team is struggling with the concept of the worse the detectability the lower the score, then don’t depend them to assign the values. Let them assign the detectability using the subjective approach (more than once per day to once every 5-100 years)or the the probability (>20% to 20% to 20% to

    Binary logistic regression can help answer the question. Minitab makes it pretty easy for this type of anlaysis/model.
