The six sigma logo stands for so many things. It represents a smarter methodology of managing businesses or departments. The logo symbolizes three areas of strength that makes any company a true leader in any industry customer satisfaction, reduction of cycle time and defect reduction. It also mirrors the total management commitment as well as philosophy of excellence, as well as other areas like customer focus, high improvement in processes, as well as ruling by measurement instead of gut feel. The six sigma logo is all about making every area of a particular organization better equipped to meet the changing times head on, as well as answer the needs of their many customers, technologies and markets all the while benefiting the companys own employees and stakeholders.
The history of the company can be traced back on the work of a Rumanian individual by the name of Joseph Juran a pioneer in US quality management. His statistical work uses the Greek sigma, a letter that measures just how far a particular process deviates from utter perfection (going back to standard deviation in statistical processes and procedures). If the sigma number is higher, then the performance is closer to perfection. He maintains that only one sigma is not enough, so he established six. Six sigma means only a mere 3.4 defects per a million. The central notion behind Six Sigma is that if you are able to measure the number of defects that can be found in a particular process, you can then figure out, in a systemized way how to get rid of the defect in order to reach zero defects.
The higher the sigma number, the closer to perfection. One sigma is not very good, six sigma means only 3.4 defects per million. The central idea behind Six Sigma is that if you can measure how many "defects" you have in a process, you can systematically figure out how to eliminate them and get as close to "zero defects" as possible.
