SIX SIGMA Meaning and
Definition
-
Six Sigma is a quality management methodology that aims to improve business processes by reducing variation and defects. It is a systematic approach that focuses on identifying and eliminating errors, defects, and wasteful activities in order to optimize efficiency and enhance customer satisfaction.
The term "six sigma" is derived from statistical modeling, where the symbol sigma represents the standard deviation of a normal distribution curve. In Six Sigma, the goal is to achieve a level of performance where less than 3.4 defects occur per million opportunities, corresponding to a Six Sigma process capability.
The methodology involves a rigorous application of statistical tools and techniques to measure, analyze, improve, and control processes. It follows a predefined sequence of phases, commonly known as DMAIC: Define, Measure, Analyze, Improve, and Control. Each phase involves specific activities and tools that guide the project team towards process improvement, while systematically addressing the root causes of defects and errors.
Six Sigma is often implemented within organizations as a continuous improvement initiative, driven by project teams and supported by management. It emphasizes the importance of data-driven decision making, as well as the involvement and empowerment of employees at all levels of the organization.
Overall, Six Sigma helps organizations achieve higher levels of quality, reduce variation, and enhance operational performance, thereby leading to increased customer satisfaction, improved profitability, and sustained success.

Etymology of SIX SIGMA
The word "six sigma" originated in the field of statistics and quality management. The term "sigma" refers to the Greek letter σ, which is commonly used to represent standard deviation in statistics. "Standard deviation" measures how much variation or dispersion exists in a set of data points.
The concept of "six sigma" was popularized by the manufacturing company Motorola in the 1980s and later adopted by several other companies. The word "six" in "six sigma" signifies the goal of achieving a high level of quality control with a very low defect rate. Specifically, the term "six sigma" refers to a statistical measure that represents, theoretically, about 3.4 defects per million opportunities in a manufacturing or business process.
