Six Sigma focus on improving the quality of the process by identification and removal of the cause of process defects and reduction of variability. Six Sigma uses statistical methods and relies on the use of trained Green Belts and Black belts who are internal and external experts. Six Sigma goals towards 99.99966% of the products manufactured, and services provided to be statistically free of defects. Six Sigma follows Deming’s Plan-Do-Check-Act Cycle. Or DMAIC (“duh-may-ick”) which has five phases, including define, measure, analyze, improve, control, and recognize.
A great way to learn about Six Sigma and become certified as a yellow, green, or black belt are Mindedge Courses and Certifications. Since 1998 Mindedge Classes have benefited over two million learners.
