Which quality management approach focuses on minimizing defects to near perfection?

The focus of Six Sigma is on minimizing defects and achieving near perfection in processes. It is a data-driven approach that utilizes statistical methods and a structured framework to identify and eliminate causes of variability in manufacturing and business processes. By aiming for a defect rate of no more than 3.4 defects per million opportunities, Six Sigma provides a rigorous methodology for improving quality and efficiency. This approach involves defining processes, measuring current performance, analyzing data, improving processes, and controlling future outcomes, commonly known as the DMAIC (Define, Measure, Analyze, Improve, Control) process.

Total Quality Management, while also aiming to improve quality, takes a broader corporate culture approach that involves all employees in continuous quality improvement, but it does not specifically target a quantifiable defect rate. Lean Manufacturing focuses on eliminating waste and maximizing value in the production process rather than specifically minimizing defects. Continuous Improvement is a philosophy that advocates ongoing improvements in products, services, or processes but does not emphasize minimizing defects to the same degree as Six Sigma does.
