The Six Sigma Methodology: Past, Present And Future

The Six Sigma Methodology: Past, Present And Future

The vastly popular Six Sigma methodology has undergone a long evolution until nowadays when it is so vastly employed by companies. It is considered to have originated from a theory put forward by Carl Gauss who introduced the normal curve concept in the 19th century. The Six Sigma approach was started in the 1920s when the three sigma deviation from the mean was the error which required to be corrected, in order to enhance production quality. A number of standards of measurements such as Zero Defects were suggested afterwards, but the concept was developed and the term was coined by a Motorola employee; it is now a registered trademark of the company. The idea was developed in the course of experiments to solve problems of the Motorola company production by means of statistical analysis. The results were really encouraging and the consequences were faster and cheaper production boasting higher quality, which was the prerequisite for achieving customer satisfaction. The methodology was formulated in a white paper entitled "The Strategic Vision for Accelerating Six Sigma Within Motorola" by Dr. Harry, a senior employee, who later headed the Motorola Six Sigma Research Institute and was instrumental in developing the concept further.The data driven methodology employed was combined with a change in management to result in a breakthrough in business excellence in terms of quality production and meeting customer requirements. It was the innovative ideas and breakthrough nature of the approach that shot the methodology to the popularity and success it enjoys nowadays on a global scale. That was a sui generis business revolution that challenged the intelligence and resources of both management staff and lower employees, who worked together as a team to achieve the common goal of the company. The tools and concept have been continuously perfected in the course of years, and the business leadership has been combined with the process improvement and error elimination tools to achieve efficiency and direct bottom line impact. Of course, the evolution of Six Sigma has been carried out by each and every practitioner of the method, each and every consulting company, each and every Green Belt, Black Belt and Master Black Belt. All of them have had their contribution to the evolution of Six Sigma. The strategies and tools have been continuously improved, and the result has been eliminating waste and strongly boosting company productivity and hence company profits. It is believed that the methodology has a great future in store for it: it has yet to reveal its true vastness of capabilities. It is incumbent on all management staff implementing the methodology to hold high the torch of development and pass it on to their successors. That can be achieved by further developing the concept and inspiring the experts following in the footsteps of currently active Six Sigma practitioners: they can take companies to the next level of success by perfecting and implementing their original thinking and creative approach. The methodology can really become a worldwide standard and boost businesses globally.
