The Lean Approach. Like Six Sigma, Lean is a tool used by businesses to streamline manufacturing and production processes. The main emphasis of Lean is on cutting out unnecessary and wasteful steps in the creation of a product so that only steps that directly add value to the product are taken.
Six Sigma is a set of techniques and tools for process improvement. It was introduced by engineer Bill Smith while working at Motorola in 1986. Jack Welch made it central to his business strategy at General Electric in 1995.Today, it is used in many industrial sectors.Six Sigma seeks to improve the quality of the output of a process by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes.his is based on the fact that a process that is normally distributed will have 3.4 parts per million outside the limits, when the limits are six sigma from the original mean of zero and the process mean is then shifted by 1.5 sigma (and therefore, the six sigma limits are no longer symmetrical about the mean).
