    Did you guys hear Chrysler is releasing the new Dodge Sigma in 2008?  Manual transmission, 4-speed, 6 gears (…shift by 1.5).

    We all hang out on South Beach together – well actually Darth hangs out with the 13th St. crowd. We meet him at the Tides for mojitos and tequilla.

    Dear Sir/madamPl. let me know how this SIX SIGMA quality concept can benefit a LOGISTICS SERVICE PROVIDER towards it’s offerings and enhancement of it’s services to it’s customers.Thanks and regardsJayant K. Varshney

    hi, can u send in some explaination for the 1.5 shift in a manner other than rigorous statistica approach.

    hi , can u send in an elaborate explaination of the 1.5 shift in a manner other than rigorous mathematical statistics. this will be help to me only if i am replied back within 3 days so please do look in to the matter

    TQM is  a  wide comprehensive  Concept
    SS is  mainly  a  methodology for  process  improvement

    hi,
    I want to obtain the comparison between QTM and Six Sigma.
    Thanks,

    It was really remarkable to read the explanatory message you gave on Six sigma performance capability 
     was going through the said site and have found many missing links to my understanding of the topic.
     
     understand that it takes some time for a beginner to master the conepts of sixsigma, even if its merely the green belt curriculum one take s up.
    Could you clarify some of the doubts I have which i have numbered out and brought to your notice below in the mail.I feel rather than going on through the details with those misses, it is better to get them cleared and pursue the learning process.
     
    1.Is  a normal distribution curve a curve with a wider area?
    2.3 six sigma readings refer to UCL,LCL and the target?Am I correct
    3.Why is 6 sigma chosen over 3 sigma capability?
    4.Could you explain through charts the 6 sigma process capability and how 3 PPM will be rejected therefrom.
     
    Very grateful if the above mentioned questions are answered with graphs and charts for better understanding.
     
    Sorry for disturbance if any
    Regards
    Mini Sherino

    Mr. Kashif,You are responding to an almost three year old post.Mr. Carnell’s point is right. If you do some basic reading on the
    subject before asking questions, the type of question he was
    responding to would never be asked.People come to this site seeking to be spoon fed. If you seek to learn,
    you will never get there by not doing some work on your own.

    Imagine someone has given you a task of driving a vehicle from one end of road ( curves included)to another , without crossing the edges of road .. what will you do?
    You will obviously select the vehicle ( 4 wheeler) ,where the distance between the 2 front and 2 back wheels “less” than that of road width.
    To optimise this you will keep on selecting a better vehicle each time so that you can “increase” the speed of the vehicle without even crossing the edges of the road.Shift from 4 wheeler to 2 wheeler will give you the best advantage.This will ensure that your “process” is within the “specification” ie width of road of the customer.

    Wow, thanks. I have been checking daiyl for such a good explanation.
    Now I can move forward on my first project.

    Sure!  No Problem!
    I’ll be in the area day after tomorrow.   Please tie a red scarf to your post box, so I know where to leave it.   If we should fail to meet, I’ll leave an extra copy taped to the traffic signal on the NW side of Bannerjee St. and Highton Rd.   -Again, look for the red scarf.

    My this thread is a long one……………………
    Lets See,,,,,,,,,,,,,,,,,,Six Sigma…………………Do you think 99.9% is good enough? Well that means 3,500 babies will be dropped on their head this year, or several hundered planes will fall from the sky………
    Sigma = square root of variance
    variance = sum of squares/ n-1 (sample)
    6*Sigma = 99.999999% yield
    maybe this isn’t so important if you are making floor tile, but it is if you are making components to incubators for premature newborns.
    Statisticly speaking……..The use of six sigma is more than the aforementioned equation, it is using all the tools to keep a tight/normal distribution centered within process specifications. Variation of a process is going to happen. How that variation exists within the process limits is important.
    Example, if you plot a process on a chart (X,Y) the process will usually trend or vary from the target or mean. Now calculate sigma and apply control limits to the process say a range of 3sigma. Yes, by looking at a histogram it appears you have variation, however if your data stays within these controls you are well within six sigma. Now break out some more statistical tools. Cp and Cpk are used in a process to tell how a process distribution is shifting. This tool allows one to examine the process using other tools to determine if it is a people, machinery or measurement system issue. Or a combination. Shewhard charts like CUSUM, Xbar-R  and XY are common tools for monitoring this process.
    In general Six Sigma does not lead to more variation, it accepts normal variation and allows for processes to be kept in complete control……by catching unstable and trending processes before they are a problem……..
