Its methodology is based on established Statistical Process Control (SPC) techniques, data analysis methods and systematic training of all personnel involved in the activity or process targeted by the program. ![]() In 6 Sigma, the problem-solving process aims to reduce variation in any given process to 6 standard deviations from the target.Ħ Sigma is a structured methodology to measure the quality of your service and performance. In other words, it is one of the measures of dispersion or you can call it variation. The Standard Deviation is a measure of how a given set of numbers are spread out. Literally speaking, the 18th letter of the Greek alphabet, Sigma(σ), is the symbol for Standard Deviation. Why is this process called 6 Sigma? The process has five steps, so why not call it Five Steps? That is because the name of this problem-solving process refers to the standard deviation that is allowed in order to achieve 99% accuracy in a process. Let’s look at a few definitions of 6 Sigma Sigma Although it leans toward production processes, it can also be applied to the transactional process. 6 Sigma applies to any process irrespective of the industry, company, and/or domain you are associated with. One of the most important aspects of this problem-solving approach is that: “Applies to any process”.
