Sigma (management theory)

Sigma in management theory refers to the use of statistical methods, particularly Six Sigma, to improve organizational processes by reducing defects and variability. It involves data-driven decision-making to identify inefficiencies and implement targeted improvements, enhancing quality, consistency, and customer satisfaction. The goal is to minimize errors and waste, leading to more efficient operations and higher standards of performance. Six Sigma employs a structured methodology (DMAIC: Define, Measure, Analyze, Improve, Control) to systematically solve problems and optimize processes across various industries.
