    Six Sigma and the Evolution of Statistical Management Methods

    Six-Sigma: the Evolution of 100 Years of Business Improvement Methodology by Ronald D. Snee.

    The article includes a nice very quick summary of the development of statistical methods to aid management improvement in the last 100 years. Then the article gives a good overview of Six Sigma.

    There are four aspects of the Six-Sigma method...

    First, Six-Sigma places a clear focus on getting bottomline results...

    Next, Six-Sigma builds on improvement methods that have been shown to be effective and integrates the human and process elements of improvement...

    The third key characteristic of Six-Sigma is that it sequences and links the improvement tools into an overall approach...

    The fourth key characteristic is that Six-Sigma creates an infrastructure of
    Champions, Master Black Belts (MBB), Black Belts (BB) and Green Belts (GB) that
    lead, deploy and implement the approach...

    Six-Sigma is based on the scientific method, utilising statistical thinking and methods (Hoerl and Snee, 2002). Statistical thinking, therefore, is fundamental to the methodology because Six-Sigma is action-oriented, focuses on processes used to serve customers, and defect reduction through variation reduction and improvement goals.


    And the article closes with a case study.
