Six Sigma is rooted in statistical process control (SPC) and utilizes data-driven decision-making to achieve near-perfect quality standards. The core idea revolves around defining, measuring, analyzing, improving, and controlling (DMAIC) business processes. By following these steps, organizations can systematically identify and eliminate defects, leading to enhanced performance.

Key Concepts:

**Defect: **Any deviation from the desired specifications or requirements.
**Process Variation: **The range within which a process naturally operates, often due to inherent random causes.
DMAIC Framework: The five stages of Six Sigma project implementation (Define, Measure, Analyze, Improve, Control).
