Step-by-step explanation:
The quality improvement and management system developed at Motorola in the late 1980's was Six Sigma.
Six Sigma is a disciplined approach to quality improvement, aimed at reducing defects and improving processes. It uses statistical analysis to identify and eliminate variations in a process, resulting in improved quality and customer satisfaction.
Moving from a three-sigma level of performance to six-sigma level means reducing the number of defects from 66,807 per million opportunities to just 3.4 per million opportunities, a significant improvement.
