    Taylor Made,
    I might be sacked by posting this message, but what the heck !! Just putting my point of view here with green light saber on and ready to block.
     PLACEBO — Hmmmmm, in a way, YES. I make a living being SS practitioner but I believe otherwise. Tools and approach are somewhat similar to those taught year ago. Only special teaching in SS was 1.5 shift thing, though the rest are not unique but only collection of tools available history ago. The good thing is that, now, most tools can be manipulated by software and give result in a matter of second unlike dates back.
    ” 6 Sigma Is Sick– and Doesn’t Provide Any Benefit”  – On this one strongly I disagree.  Using the tool (old or new) and the methodology could lead you to a some sort of improvement whether how small it is, therefore, benefits are there and SS is not SICK.
    Ahhhh…too lazy to post message. Hope you got my point….

    TC,
    In fact, WE have same sentiment. Unfortunately, this kind of spanking send wrong image on other peers. Who knows, maybe someday, somehow, we will be reporting to Six Sigma (MBB) practioner who doesn’t know how to do a Box Cox transformation.

    Kingpin,
    Selecting SS BB project varies differently on every firm. Your company should have its own criteria to follow developed by your Quality Department or plant MBB. Criterias should be agreed upon by your top management inline to your business strategy and KPI’s.
    Anyway, here are some of the list you could consider;

    Results or Business Benefits Criteria
    ¡¤         Impact on external customers and stakeholders
    ¡¤         Impact on business strategy, competitive position
    ¡¤         Financial impact (USD)
    Low impact :       < 100K
    Middle impact:   100K to 300K
    High impact:       >300K
    ¡¤         Urgency
    ¡¤         Trend (Is it getting bigger or small? What will happen if we do nothing?)
    ¡¤         Sequence or dependency (Are other projects dependent on this issue? Does it depend on other problems being addressed first?)
     
    2.0 Feasibility Criteria
    ¡¤         Resources needed (people, time, money)
    ¡¤         Expertise available (Do we have the needed knowledge or technical skills?)
    ¡¤         Complexity
    ¡¤         Likelihood of success ( Based on what is known, how long it needs to success?)
    ¡¤         Effort needed (Low, Middle,  High)
     3.0 Organizational Impact Criteria
    ¡¤         Learning benefits (What new knowledge might we gain from this project?)

    Cross-functional benefits (To what extent will this project help to break down barriers between groups in the organization and create better ¡°whole process¡± management?)

    Ronald,
    Demotivating, yes I should say. But, I have done it on purpose though. Who would you think will make the spanking here if you have seen someone straying on the great idea of SS methodology ? Or, your are one of those unfortunate people wanted to be GB, BB, or MBB in the promise of good fortune that it will bring to you.
    Also, would you please get back on my previous post. Its state there that ;  MINIMUM savings for a GB project. Its not the amount ($) that matter in the our certification of GB, its on how the way they utilized the tools.   
    Do you notice how SS was spreading nowadays?? Is there any QUALITY and PRIDE left ?? Or was it utilized to gather more with less?? Was SS becoming a FAD as what had happen to TQM?? Only you can answer and I hope you noticed it.
    PRIDE are loss everytime we see post asking how can a single person earn more even still in the process of certification.
    Hey, just my sentiment.  If you can’t take it, don’t read my post. You will feel it later. The “FORCE”,  I mean…Anyway, that’s where the name stands.

    Sri Harsha,
    Wow. Greenbelt is a great accomplishment !!  But before I answer your question, would you be so kind to answer mine?
    What is Six Sigma anyway?? Why is it useful to have such methodology in place?? Can we use Capability Analysis in determining how much PPM is outside the specification for a process with Exponential distribution?? You know what is the difference between F and t distribution?? When do we need to use F and t-distribution?? How many kind of process / service distribution do you know?? How can we treat / correct multi-modal process?? How  many documented succesful projects you have created?? How big is the savings??
    Six Sigma is no a fad but it will be soon if there are people focus on how much they could earn on a certification probably they deserve (who knows). Not because you have the certification or pass the examination, means you can get something and you can do the things already. You need to earn and prove it. And you can prove it by the numbers of successful project you have luched. I have trained several GB in my organization and three (3) project in a year is the minimum requirement with total saving of US$ 20,000. Then, the certification.  
    You can do project in your own organization since SS applies both on process and service.

    Its only for your randomization purpose.
    Say, you have ten standard (order) test run (sample) but you need to run it according to run order stated in your experiment.
    If you are using Minitab, go to DOE>Create>Option> unclick the randomize run and you will see the result.

    Ted,
    Wonderful. You have just pulled the string by yourself.
    You are already in the right approach by convicing your company and to look-ut to other company that might be interested for your SS project (practice). Anyway, the best way you could do is to convicnce your immediate superior and show to him/her the advantages of using SS by a simple presentation. Normally, if they are not aware on what are the benefits of using SS methodology, they really could have second thought. It is in a manner of presentation and delivery. Offer to your immediate boss, that you will be doing the project (with savings $$$) on your extra time with no additional cost to the company or compensation. You only need to get your boss approval and the support of your team member and whollla….
    Offer the same on the other company with the word “FREE”. Though it is much more difficult to do the project in other company due to culture and supporting, you can be creative in making an offer.
    You could also ask ASQ to help you on this matter.

    Vinay,
    You might be confused between SS Project and Quality Improvement? In doing a project, you need a strategic planning in consideration of everthing most importantly now; COST.. Impromtu thinking are not to be considered a project. You are paid to show the after (MONEY $$) effect. Please be guided. 
    Project are define as definite formulated piece of research or plan undertaking. In doing a project you need to at least provide; Problem Statement, History, Objective and Goal, Cost Analysis (including ROI), Members, Action List, Analysis, Improvement Plan, Conclusion and etc.
    That’s the difference of SS among others quality methodologies. Don’t spread wrong analogy and impression in this forum.

    I guess that is the reason why is is called “DRAFTING”.
    Anyway, defects are classified usually by the end user (costumer).Call a “VOC” meeting to list down thier requirements. Costumer have two category, internal and external. You might want to consider your internal costumer first. Else, you will be execrting all the effort and go brain dead. Surgery are expensive these days. :-) unless you do it in Death Star with Vader. hahaha.

    Mr. Conforti,
    You can do this:
    Minitab> Stat> Control Chart> R… input there your data and your done with the graphical analysis.
    Why do you need specs in R chart anyway? Are you confused or something. You might wanna use Capability Analysis (Index)
    It is very hard to show and explain something to your boss if you don’t know what is it you wanted and what it is your doing. If you do such, it will also make your boss utterly confused.
    If you have variable data and specification (USL/LSL), use capability analysis to show process performance to your boss. Minitab can provide an excelent graphical presentation that you and your boss might take some time time to ponder. Who knows, he might might give you a pat in the back for this great work or it might be in reverse.
    Need to go. A lot of droids to fix. You might wanted to borrow R2D2 or C3PO for this purpose.

    Downfall of Six Sigma can be realized if you have ever encounter some obvious scenario below:
    1.0 Utilizing a bunch of dim-witted and obtuse BB on a very simple project with savings $6K to $10K per year.
    2.0 Re-training of fore mentioned BB’s whereas after training still doesn’t know how and when to use Box-Cox Transformation.
    3.0 Having MBB that doesn’t know inferential statistics and hates or more likely afraid coaching dim-witted BB’s.
    4.0 BB’s and MBB’s alike posting on this forum asking stupid questions that are already being taught on thier training as if SS tools are merely new set things.
    5.0 Wookies that wanted SS for certification purposes which are being taught by dim-witted, non- experience BB’s and MBB’s for a sure dollar certification and consultation.
    There are plenty of other obvious signs that you can’t miss out. Just that I’m battered by my laziness and worried to be hit back by my own green light saber. Need to go back in Death Star after my surgery to pick-up some of that droids.

    Base on your post, you know how to calculate the Zst, PPMst, Cpkst You know the formulae and how to use them.
    To calculate Long term, just Subtract 1.5 to your Zst thus Zlt = 2, then you get the 22750.  
    Zlt = Zst – 1.5

    Carlos,
    Particle Size Distribution (PSD) are commonly measure using Laser Diffraction Spectrometry (LDS) thus giving the result in a certain distribution but not commonly Normally distributed. This could end up data set with outliers either on both side of your distribution tail including the outliers. Using MEAN of the data set could be misleading since it is greatly influenced by an outliers. MEDIAN are much more suitable for the data in your Cpk calculation since it is less affected by outliers. These are true only if the powder didn’t pass mesh holes for specific powder sizes,  else use the MEAN data.
    If you are monitoring the entire production plant particle atomizer, your data gathering and performance measurement might be suitable but may not be correctly performed and utilized. Since the data are not normally distributed, you can’t use Cpk index since it assumption are either in Normal or Weibulls distribution. You need to transform your data first, then you can utilize. 
    If you are to perform individual particle atomizer analysis, you need to compare distribution data of PSD for each atomizer per each specification (same product) and compare how it deviates from the mean. If you could get the data set in distribution calculation in LDS, you could plot overlaying each other thus you can analyze properly.
    If you could get PSD data set,  why not monitor your process using SPC? In this way you can do both. Monitor the process  and measure the performance. This way you can reach quickly when there are drit to your process.
    Just one cent.

    Check DOE report if the result are in actual production use. Correlation of same measuring equipment. Attribute MSA for Inspector if any.
    You might want to consider the following though it is not SS tool:
    1.0 Data Gathering Methods. Including its control, feed-back system, improvement tracking system, reporting, checking and corrective action tracking. Randomly verify also the SPC since they might try to make it look good only in time of your audit
    2.0 Personel’s training and Trainers Training Records. Pick actual people away from the audit point and look for his/her training record.

    Luke,
    Need not to get far. You’re already at the site (https://www.isixsigma.com)  where Sigma Calculator is available and ready to be use (Upper Left Corner). For more information, Sigma calculator are created with consideration to the Normal Distribution and with effect of the empirical data 1.5 Sigma Shift process variation. (Which some claimed from Motorolla data with range of  1.4 to 1.6 Process Sigma Shift). Thus, 1.5 sigma shift was an assumption that the process will behave along specific time frame. Quite big ….Huh !!!
    Will it provide you believable answer? It depends on where you stand, the way you use it and to the people you’re presenting it. Some claims it works for most of the people that use it to measure thier process and make necessary improvements. In my point of view, Sigma Level was useful in the absence of history data, as reference, comparing performance and other that you might think of . Sigma level are usually use by Manager having hard time on statistics norms that they dont bother to understand. I don’t know if there are Engineers, BB and MBB alike, out there excerting time and effort solving Sigma level if PPM or DPMO are already known, unless of course his boss asked him to do so……
    Can you use it in log-normal distribution data? Yes, why not. But it will not provide you correct answer since it is in assumption to the Normal Distribution as previously stated. Unless you tranform your data from Log-normal to Normal Distribution (Box-Cox or Johnson Trans) or create your own little Excel spread sheet.  
    I am an MBB, though you never ask. But have different view with regards to this 1.5 sigma shift that spreading like a wild fire among new and younger peers of this site as well as to the new BB / MBB. But until they provide verifiable data for this ghost (1.5 sigma shift, why not 1.4 or 1.6 sigma shift), I will remain in the DARK SIDE of the force and I will not be alone since I am with your FATHER LUKE. You may not wanna like to be my PADAWAN.

    Sigmaman,
    For simplicity., lets consider only one factor (cause of variation) the amount of sugar to be put in a cup of coffee. Let say., you happen to establish a pretty good mixture combination for a cup of coffee whereas sugar amount is = 0.55 kg +/-0.026 kg.  Variance there are the those data difference away from the mean (0.55kg) eveytime you mix a new coffee. 
    For the quality taste of coffee, there will also have other variance developed. 
    Note: Just for analogy example. Don’t use in real life. It is dangerous for your health. You might catch Diabetis.
    Now, I have the Force. Welcome to the dark side.

    Variance in explain in layman’s term:
    If you are to make an instant coffee, there are several causes of variation there: cup, coffee, sugar, creamer, water, spoon, temperature, humidity, mood and etc that you can think of.
     Variance are the difference in the amount from the mean of such factors each you mixed to make a coffee such as the amount of coffee, sugar..etc….thus your response here are the quality taste of the coffee itself. 
    Hope you get the idea. Someone caould make a much easy analogy for your understanding.

    I don’t exactly know if you understand what you are doing or you wanted us to jump on the mud pit that you have created. Frankly enough, you doesn’t understand or refuse understand the application of PDCA (Plan, Do, Check, Act) and DMAIC (Define, Measure, Analyze, Improve, Control) thus you wanted to make your life so complicated and miserable.
    How can you use DMAIC in PLAN stage of your PDCA? DMAIC in your DO stage? and so fort and so on. What can you possibly re-re-re-Analyze in your ACT stage of your PDCA. Hey, even me I am in total lost only just by answering your message. Bottomline is you cannot do it. MAKE YOUR LIFE SIMPLE as well as your analysis. You are paid to make results fast not on how many times you use the tools or methodology and how good you use it.
    One more thing though, Six Sigma Methodology (DMAIC) are commonly use if the cause of the problem are UNKNOWN. If causes of problem are known, all you have to do is use the quality analysis and improvement tools you have learned and control your process…Dont forget the most important one…… “The COMMON SENSE” which perfectly works most of the time.
    Please stop mixing things up and dragging others to your quick sand. Some novice might think otherwise and copy your idea which I hope not.
    Anyway, if you happen to create such wearisome and mind buggling studies of yours, please DO NOT INFORM THIS FORUM. They might asked for a copy of the paper.

    This always dependent to your application suitability. Both will be sufficient if it was coupled with your own ingenuity and skills. Be sure to asked correct question and hope you get the best answer with application example.
    Unfortunately, most of the e-learning or classroom experiences are focus on earning a nickel with a less quality teaching and are all book based example. Find someone with credible status before plunging into a deep sh?t and the select the one worth your money and effort.

    Aman,
    A good question will deserve a good answer. Then:
    As a layman’s shortcut explanation, Six Sigma is not totaly came from a statistical analysis though it uses statistic on the calculation of DPMO / PPM under the area of a normal distribution, the effect of 1.5 sigma shift is applied. The sigma shift is an empirical data from previous studies of those people pioneering SS methodology, from which they claim that it is from observed process long term variation of 1.4 to .16 sigma shift. Until now, with long discussion, this shift and the data of calculating the 1.4 to 1.6 sigma is not avialable. Thus, these shift are now merely an assumption that your process will shift as much as 1.6 sigma.
    Fortunately, the methodology works fine, but the 1.5 sigma shift is ???? up to you to utilized.  
    Try to search this site for more information.
