Paraphrasing (18th paragraph)

Text

Welch launched the effort in late 1995 with 200 projects and intensive training programs, moved to 3000 projects and more training in 1996, and undertook 6000 projects and still more training in 1997. So far, the initiative has been a stunning success, delivering far more benefits than first envisioned by Welch. Last year, Six Sigma delivered $320 million in productivity gains and profits, more than double Welch's original goal of $150 million. This year, he expects GE to get about $750 million in net benefits. "Six Sigma has spread like wildfire across the company, and it is transforming everything we do," boasts Welch.
