A data-driven technique for eliminating defects in a process is referred to as _____________.

• A. Kaizen
• B. Total Quality Management
• C. Quality Assurance
• D. Six Sigma

Answer: (D)

Using data and statistics to identify and remove the causes of defects in a process, with the aim of reducing variation and improving consistency. Six Sigma is exactly that kind of approach: a structured, data-driven method that uses statistical tools and the DMAIC cycle (Define, Measure, Analyze, Improve, Control) to pin down root causes and implement fixes that dramatically reduce defects. It also emphasizes a quantitative goal, often described as reducing defects to about 3.4 per million opportunities, which highlights its focus on near-perfection. Other options describe broader ideas rather than the specific, data-centered defect-elimination method. Kaizen centers on continuous, incremental improvements and can be less formal about data and statistics. Total Quality Management is a wide quality-improvement philosophy across an organization. Quality Assurance focuses on ensuring processes and outputs meet requirements, but not necessarily through the rigorous, data-driven defect-reduction framework that Six Sigma employs.
