PPT ON BASIC SIX SIGMA
Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving toward six standard deviations between the mean and the nearest specification limit) in any process – from manufacturing to transactional and from product to service. Six Sigma is a method that helps in developing and delivering desired products and services by eliminating defects. It measures the deviation of any process from perfection. The main idea behind Six Sigma is to measure the number of defects in a process and to eliminate them to get as close to “zero defects” as possible. To achieve Six Sigma in any process, it must not produce 3.4 defects per million opportunities for each product or service transaction. Six Sigma can therefore be also thought of as a goal, where processes not only encounter less defects, but do so consistently (low variability).
