![]() ![]() The unit of measurement usually given when talking about statistical significance is the standard deviation, expressed with the lowercase Greek letter sigma (σ). He transformed GE to a state where Six Sigma had become the culture of the organization and not just a methodology for brining organization-wide improvements.It’s a question that arises with virtually every major new finding in science or medicine: What makes a result reliable enough to be taken seriously? The answer has to do with statistical significance - but also with judgments about what standards make sense in a given situation. He changed the performance incentives and made them based on individuals ability and enthusiasm to take part in Six Sigma initiatives. ![]() He implemented Six Sigma in all areas and ensured that the entire organization participates in the initiative. ![]() In 1990s Jack Welch launched Six Sigma in GE in a big way. Looking at the success of Motorola, many companies like Texas Instruments, Allied Signal etc started using Six Sigma methodology to bring organization-wide improvements. A few years later Bob Galvin launched a long-term quality program called The Six Sigma Quality Program in Motorola. Mikel Harry having a doctorate from Arizona University worked with Bill Smith in developing a four-phase problem solving approach - Measure, Analyze, Improve and Control. It was accepted by everyone but the challenge that came in front of Motorola executives was to develop a solution to tackle this problem. In his report he discovered that the products with fewer non-conformities (high quality) were the ones that performed well after delivery to the customer. To achieve the same, strong emphasis was given to training of employees and also performing global benchmarking.īill Smith was a veteran engineer in Motorola and he wrote a research paper on product quality and its performance after delivery to customer. He challenged his organization to achieve a ten-fold improvement in performance over a period of five years. The CEO of Motorola - Bob Galvin was determined to overcome the competition. In the year 1980, Motorola started facing survival problems due fierce competition from Japanese companies. ![]() proven technique for quantum jumps in business results.global competition - Japanese and Chinese threats,.rising customer expectations in terms of quality, delivery and cost,.The need for process improvements and a continuous improvement methodology like Six Sigma came into existence only due to Sigma Level Vs Number of Defects Sigma Level It focuses on the bottom-line and is a proven methodology for problem solving. It can also be used to bring breakthrough improvements in the process. In other words, it is a methodology to achieve 3.4 defects per million opportunities. It requires thorough understanding of product and process knowledge and is completely driven by customer expectations. Six Sigma is a data-based methodology to improve performance by reducing variability. ![]()
