The primary focus of Six Sigma methodology is reducing variation in processes. Six Sigma aims to improve the quality of outputs by identifying and eliminating the causes of defects and minimizing variability in manufacturing and business processes. By striving for near-perfect processes, Six Sigma helps organizations deliver consistent, high-quality products and services, which is critical in healthcare for improving patient outcomes.
Complying with standards (B): While Six Sigma can help meet standards, its focus is on reducing process variation.
Eliminating waste (C): This is a primary focus of Lean methodology, not Six Sigma.
Improving patient safety (D): While reducing variation can improve safety, Six Sigma's core goal is to minimize defects and variability.
