    When dealing with with Cost, Schedule, and Quality, there are many processes that influence the outcome. Should a dashboard that is viewed by a president of a corporation be one that reports the outputs (budget – cost = output)? If not what should it report?

    There is a brilliant ‘dashboard’ in ‘The Cabinet War Rooms’ London. Part of it reads:
    Aircraft Casualties
    Period Sept. 15th 1940
    ENEMY
    Destroyed = 183          (.. in Red)
    Probable 42                 ( ..in Yellow)
    Damaged 75                ( .. in Green)
    Our A/C Pilots Safe 28
    What could be more succinct …God Bless our armed forces!

    Andy U,
    What’s all this about? Are you losing it like Regile. I expected more from you.

    Pardon? Yeah, you have lost it. I guess you lost it when nobody wanted to read your “paper” and give you “credit” for the Six Sigma invention. God Bless you. Please tell us some more about your queen and your country because you know life this side of the ocean is soooo boring.

    Who are you kidding … I mention something from 1940 at a time when London is preparing plans to evacuate the population – its obvious what side of the ocean you’re on.
    As for my article, I never claimed anything.. what have you ever done? Chopped any heads off recently?

    Andy U,
    No. I actually celebrate the 4th of July every year. Doesn’t take a genius to know that it is the best thing that ever happened to US. I think your initial post in this thread was inappropriate. I am out of this thread!

    Hi Mman,
    The article was published a long time ago – 1987 – and is no longer available from Semiconductor International. If you’re still interested, I’ll send you a scanned copy.
    Basically, it is about how to characterise a typical semiconductor process. The techniques described are based on Shainin’s lectures. It also used a five, phase cycle, which was first documented and circulated within Motorola by Jack Scholls of MOS 3, who was a student of Juran. Of course, these days I mainly use Taguchi Methods.
    Best regards,
    Andy

    Hi Mman,
    Just to let you know that my email provider is down again, and hotmail seems quite frugal with it’s upload file size; so there may be a delay regarding your earlier request.
    As for the link between Single-flow and Six Sigma I’m not sure there is one. After all … single-flow makes wide use of poka yoke, or self-assured processing. (The latter refers to making measurements as close to a process step as possible, usually automatically, to guarantee the part processed product meets requirements.)
    This seems quite different to Six Sigma, but I am willing to be re-educated, because as I understand it one of the goals of six sigma is to have a ‘natural varation’ much less than tolerance limits. Obviously, this is a good principle, but it is not always practical, or even cost effective, and can therefore sometimes can lead to uncompetitiveness.
    I’ve already cited the example of fast static RAMS, but there are many other products and processes where our skill is to actually run the process very close to the edge of a precipice without actually killing the product, our reputation, or the customer’s business. This is where the Taguchi loss function can be used to great advantage – to balance competing requirements. Unfortunately, its use in practice is often regarded as too complex, but I hope my earlier posting will provide a simpler view of the loss function as the ‘mating’ distribution, as described by Shin Taguchi. Other examples, where performance is everything include image setters, ink jet, microwave antenna, and biological sensors.
    This also seems to be true of other endeavours, such as Intellectual Property, where patents have to be written without error. How is this to be achieved first time? In practice, patent attorneys write a patent, read it three times, read it backwards, and then ask colleagues to review it. These are sensible precautions in view of the potential losses.
    I would be interested in your view and the view of others.
    Cheers,
    Andy

    Hi Andy:I like your way of thinking as Taguchi maintains that  a product does not start causing  losses  only  when  it is  out of specification,but  when there is  only deviation from  the target value..This leads to the important conclusion  that quality is most economically achieved by minimizing variance  rather than  by strict conformance  to specification,which  is similar to the SS  Concept.This  also provides  the basis  for  the Taguchi’s ideas for off-line  quality control.I think that  Taguchi concept is very identical  with the SS Concept:DFSS as it emphasizes on such  stages:system design, parameter design  and tolerance  design.What is your opinion?Regards

    Hi Mman,
    Where can I send the info. you requested?
    It is possible to decompose the loss due to setting errors and the loss due to the variance magnitude.
    I have a slightly different view of Quality – I think Quality is like a microwave matching circuit. When there is a good impedance match, power is transmitted efficiently; but when there is a poor match, reflected power gives rise to losses and can even heat up the output stage and damage the transmitter.
    If you think that Taguchi’s approach is the same as Six Sigma, you might like to read:

    Al,
    I think Hotmail bounced the large file back. I’ll try to provide you with a link, but it will take a couple of days as I’m still working on another project.
    Cheers,
    Andy
