Simple explanation of Six Sigma. Six Sigma was found in 1979 by Motorola. However, it was popularised by GE. Six Sigma is represented as 6σ. It is a methodology to improve quality of a process. Before we actually start learning Six Sigma concepts it is essential to learn what is Six Sigma; Why is it implemented; Where is it implemented and so on. Primary difference between Lean & Six Sigma is that Lean is implemented to improve the cycle time or Turn around Time or reducing the time of the process. Six Sigma is implemented to improve the Quality of the process. Improvement found by Six Sigma would always be a giant leap in the process. It is not a gradual improvement. Example, savings in processing expenditure would be reduced from 100000 to 80000. It is not a gradual reduction like 100000 to 95000 then 90000 etc.
