    Minitab recalculates UCL, LCL and average p for every data point added/subtracted/modified in the population automatically (unless programmed otherwise).  Staging is meant to indicate a major “change” to the process.  In our situation, it means that a special cause has been identified and “handled”.  Once done, this point is taken out of the population. 
    At issue is the lack of “closure” on the special causes and that removing the point(s) somehow makes the control chart more meaningful.
    Mechanically, your description is correct, the logic and philosophy of removing or staging the data is what is in question.  Thanks!

    I want to thank both of you for your responses and I would encourage anyone else to provide their input.  So far the best definition seems to be that of Rhineg.  If you have a better definition, I’m listening.

    JC,I realize that your post was a while back but figured others may stumble across this thread looking for some help picking a SPC software solution. We’ve used WinSPC (http://www.winspc.com) and been really happy with it, it does everything that we need it to, plus there’s a free 2 month trial (or something like that) so you can give it a shot before you actually buy it.Just my 2 cents.

    Wrong as usual – read this
    Most Reliable of 2006
    By DAN LIENERT

    See the list here

    Wondering why the Japanese automakers are eating up market share that formerly belonged to Americans? Here’s all the explanation you need.
    There is nothing, a Wall-Street adage says, that a bit of good product won’t cure. The Japanese know this, and they have let good vehicles drive them to financial security and sales volumes that never seem to stop increasing. This month’s New York International Auto Show saw the unveilings of two new and improved Japanese cars — the next-generation Mitsubishi Outlander and Lexus LS models — but the old, outgoing models they are replacing were already among a dozen or so of the market’s most reliable cars.
    When we look at the slide show that follows this piece — a list of the nine most reliable cars on the market — one question comes to mind: Where are the American cars? While certain U.S. companies, such as General Motors’ General Motors Buick subsidiary, are building increasingly dependable cars, only three brands — Honda, Toyota Motor and Toyota’s Lexus subsidiary — meet the most stringent standards for reliability.
    Click here for the slideshow.
    In particular, those three Japanese companies are the only companies on the market to have individual models receiving top reliability marks from both Consumer Reports and J.D. Power and Associates. Each of the nine cars in the slide show received a “predicted reliability” rating of “much better than average,” the highest possible, from Consumer Reports, and five out five stars in J.D. Power’s “overall quality” and/or “overall dependability” assessments. Each car in the slide show is Japanese.
    While American cars are built better than ever these days, they still are not as reliable as Japanese autos. With such new cars as the Chrysler 300 and Dodge Charger sedans, DaimlerChrysler has shown recently that American cars can have world-beating style. Cadillac is showing that American luxury cars can keep pace with European competition. Now, an American automaker needs to challenge Toyota and Honda in terms of reliability, and the process begins by studying what has worked for the Japanese.
    Lexus’ old slogan was “The Relentless Pursuit of Perfection,” and it wasn’t just lip service.

    The Least-Safe Cars ’06

    While the company has world-renowned manufacturing methods, “the pursuit of perfection” is inculcated so vigorously into Toyota’s corporate culture that Lexus’ trademark reliability is engineered into cars before they ever hit the factories. Quality is monitored every step of the way. Failure is not accepted.
    All major automakers build preproduction prototype models to iron out design, engineering and manufacturing wrinkles before mass production. In recent years, Toyota became known for building around one-tenth the number of prototypes per production model that automakers such as General Motors would. The only way Toyota and Lexus could do this was by learning to engineer parts that don’t fail.
    For the Japanese vehicles in the slide show, the superior reliability ratings in question concern ratings for new models. In preparing our list, we excluded from consideration all nameplates that are headed for discontinuation or replacement. This kept such reliable, outgoing cars as the aforementioned Mitsubishi Outlander and Lexus LS from the list.
    Not every car has reliability ratings. Such new cars as Audi’s A3 hatchback need to be on the market longer in order for customers to generate information on problems the vehicles may have. And such blue-blooded cars as Maybach and Bentley models tend not to have reliability ratings because their volumes are too low to make for effective studies.
    The difference between J.D. Power’s “overall quality” and “overall dependability” scores is that “quality” concerns owner-reported problems in the first 90 days of ownership, and “dependability” concerns owner-reported problems after three years of ownership.
    Please follow the link below to see the results of our research, and to see why Japanese cars are still setting the standards for which American cars should be aiming.

    Editor’s note: Consumer Reports’ reliability ratings came from the organization’s Web site. At press time, Consumer Reports had not confirmed the data despite multiple e-mail messages from Forbes.com requesting it to do so.

    The CEO is uncommunicative and his first level is going through the motions, a person without experience is in charge in both Milwaukee and Cleveland, the people with real experience are leaving fast and internal folks are staying away because of lack of support. Other than that, things are going well.
    PS – Their stock is doing well.

    Take some clues from your mfg departments, then go to your suppliers and make sure all concepts are applied there.  If your suppliers are not efficient, this can be a large area of opportunity.

    Chris,
    Thanks for the response. The suppliers each have individual part prints for the many components they’ll be stamping. After stamping the components, they weld them into an “identical” complex assembly. Both the components and assembly are measured by prints. The assemblies each need to be “identical” because they are being shipped to final assembly plants and used in a product being assembled in two different locations.
    The possibility exists that one supplier may need to provide back-up for the other should a tool go down due to damage.
    Reliability requirements are HIGH.
    Your thoughts are appreciated.

    I would point you towards areas that cause the most frustration such as improving the testing process, improve quality of requirements, or improve the estimation process.  Usually look for where the major headaches are.  We did a DOE on response time of our time reporting tool.  IT is a ripe area for this and usually there is ample data that can be collected automatically.  Tools like FMEA, Mistake Proofing, Mapping and CTQs have proven reliable for me.

    We met with one of these guys a few years ago when we were investigating Six Sigma consultants. Our schedule was to have dinner with them on the first night. They were late but dressed in all their cowboy regalia. It didn’t really impress a group from New Jersey They immediately started into a dialogue about how they don’t talk to people like us and how we were at to low of a level in the organization to speak to and on and on.
     
    Our group made plans to leave the next day before the meetings took place. There were some fast talking phone calls that our changed the plans and we ended up staying. The attitude was more than any of us were willing to endure. We hired another company.
     
    That must be how they build a thriving business? It seems unusual that a group of people from Motorola who drove Total Customer Satisfaction as a goal would behave like this.

    Chris,
    Have you noticed how folks like Stan, Darth, and Mike constantly post messages here? Most of the time, their posts have nothing to do with Six Sigma. They are just using this website as if it is theirs to socialize.
    They have one thing in common though. They are all consultants. These consultants got too much free time on their hands. They teach the same stuff over and over, flash their fancy PowerPoint slides, and then move to a new client. Then, we, employees, have to clean up the mess that they created.
    It is much easier to show a PPT file than to implement it!

    I’m not looking to train BB’s, I will recommend outside training for that.  I think we are just looking to train GB’s to utilize 6sigma in their areas, and if they complete a proper project I would like to certify them (as GreenBelts).  I was just looking for a training package if there is one, I guess I could develop one but it would take more time than I currently have.

    Anonymous,
    I read this forum almost every day. I read it because there are a lot of great questions and answers. People get “flamed” on this forum when they ask dumn questions — questions that could easily have been found by reading two to three pages on this site, or searching using the box on the top right of each page. This is not a forum for dumb questions to be asked.
    The second reason why people get “flamed” is for writing dumb statements — statements that obviously cannot be verified and are of only opinion (“stick to the facts, maam.”). A part of your last post you stated “…the ASQ material is probably the best and it’s geared towards the ASQ Black Belt exam.” This is one of those statements. How do you come to the conculsion that the ASQ materials is probably the best? The best at what?…passing the ASQ test? Well, maybe but who says it’s better than the Indiana Quality Council and if it’s you that says so, state your data.
    There are such things as dumb questions, and they come from people who are lazy or speak without data.

    How do you use excel to map?
    What I hate about visio is how time consuming it is to create a map.  you should have a spreadsheet to enter Inputs, Activity, Dec Boxes, etc and have the map generate that way.  Does Excel do this?

    Rubberdude,
     
    Thanks for the forthright response regarding your qualifications and your thoughts on putting too much credence in anonymous forum postings.   I take it from your response that you have experience in quality assurance and the statistical and technical tools associated with the field.   And while you have no specific training, certification or project experience in Six Sigma, you try to give fact based and data driven advice when posting in the isixsigma.com forum.

    What is the extent of your Six Sigma training and project experience?   You present as a subject matter expert and it would be good to know your experience level and background.  After all, we Six Sigma novices tend to take the words of the experts at face value.

    We are being told that CPK is required to show the quality of the parts. By looking over the data. I am not sure it is a very cost effective way of showing the quality. We have some parts at are always on the high side. This makes a bad CPK. We are trying to get 1.33 cpk.

    “Then it hit me – the only thing that matters is what happens when the motorcycle is shipped and/or the customer comes to take it out for a test drive!…. Just imagine what would happen if he did not have a big smile on his face after the test drive and also if he goes around telling all his super rich friends about the lousy job that they had done.” 
     You have through logical deduction and mathematical analysis reached the true essence of Six Sigma contribution.  Bravo.  Nothing beats a smiling test drive.   All of that other stuff, e.g., TRIZ, Lean using value stream mapping, reliability test designs, Eyring models, TPS, etc., etc., etc., that get bounced around and intertwined in this forum, meshing together developmental and manufacturing concepts trying to show interrelationships is obviously crap.   Take’er out for a test run and if you come back smiling whatever you did to get there must have been right.  I like it and am OK with it.  Like you said earlier, say it and move on.   I’m also OK with that.

    I would not wast my time and money on a single trial that will only tell me if there is an improvement or not.  Especially if you need over 16 runs to determine the results. 
    You would be much better off with a designed experiment exploring the factors and interactions between factors that cause your leaks to occure.

      It is difficult to determine when we added business that they might’ve not received if not for our service.One common response is that they tell us that they would’ve gotten that business anyway irrespective of their use of our service.

    Xash,
    You nailed it on the head and I sincerely appreciate your comments on this thread. To quote you: “Quality does not mean that the strategy is ‘right'”. This is the most important part and many people think Six Sigma should be the magic elixer for business success. It is the elixer for process success, if done properly.
    Thanks again for your thoughts.

    As I work more and more with business improvement projects, I’ve become convinced that the “soft” issues are the most difficult, critical, challenging, frustrating and even interesting issues.  We’re good at identifying problems, root causes, redesigning processes and moving people around on the org chart, but the lack of sustainable results always goes back to the people and the extent to which they resist change.  Another good book on the topic is Kotter’s “Leading Change”.
    As an internal consultant at our company, our improvement methodology calls for a stakeholder enrollment activity for every project and when teams attempt to brush it aside, we trot out the info and data on projects that have failed due to ignoring this critical aspect of any project.  We also have an internal Organizational Effectiveness consultant available for our teams as a resource for coaching, consulting and training.

    Hi Tony,

    > Which companies are providing training on 6 Sigma.

    I looked at the six sigma consultants page (https://www.isixsigma.com/co/six_sigma) and saw the academy and a company called Mulbury. I know another, but it escapes me now. I’ll write more if I remember.
