Six Sigma is best described as which of the following?

• A. A Budgeting Framework
• B. A Customer Service Standard
• C. An Inventory Management Technique
• D. A Data-Driven Approach To Reduce Defects In Processes

Answer: (D)

Six Sigma is a data-driven approach to reduce defects and variation in processes. It relies on measuring performance, analyzing root causes, and using a structured improvement path (Define, Measure, Analyze, Improve, Control) to eliminate sources of error and sustain gains. The goal is to drive process capability toward near-perfection, often framed as very few defects per million opportunities. This makes it different from a budgeting framework, a simple customer service standard, or a basic inventory technique, because its core purpose is systematic quality improvement through data and statistical thinking.
