    Being new to this forum and to six sigma I appear to have  a major lack of understand between the difference between TPS and six sigma.  Please assist me if you can.
    As a student of TPS (14yrs) I have found that starting with an A-Plan (corporate level expectations, 50% reduction in defects, 6% improvement in quality, etc), the managers are tasked with B-Plans (What actions are you going to do to address these issues), which tasks the Supervisor with C-Plans (specifically what is to be done, by when, by how).
    This leads to continuous process improvements with every department contributing to the goals of the plant.  Even though each department is specialized in what they do, we are all moving in the same direction.
    How is the six sigma program different?

    TPS is organized and logical. If you are disciplined in TPS you are sucessful.
    Six Sigma is the wild west, millions of gun slingers thinking they are the latest and greatest. Most are failures

    It appears that SS is still in the early stages of development.  As in the early stages of TPS, many modules were developed as part of the TPS development, but not great understanding of the total picture.    It appears that isixsigma has a lot of work to do to standardize its processes before they this CPI tool gets too far out of hand.  (Including total picture). In the mean time padawans, be patient.  It appears that at this particular moment SS is simply a tool.  How each trainee uses this tool can only be benificial as long as these activities lead to CPI (Continuous Process Improvement).  As far as Levels…..hummm, I’m not convinced that levels, yellow belt, brown belt, green belt, black belt, pink belt should dictate how competent one team is over another.  Is it more important to say, 1 SS event caused a cost saving of $250,000 annually, or 10 SS events cause a $25,000 combined savings and eliminated 10 problems that we have had for years.  Which is more valued?  and who is valueing it, the share holders or the people who had the problem?  Is not the actual goal, CPI, elimination of waste, team work, that is the real value?  And $$$ just a particular measurement.  Who is measuring customer satisfaction?  Who is measuring number events per month?  Who is measuring employee satisfaction?
    If my perspective is not correct, please correct me.
