Driving a Zero-Injury Culture

Six sigma quality objectives aspire to reach a three-parts-per-million error ratio at a 99.9996 percent incidence. The same tools and tactics that are employed to ensure product quality can become part of an action plan to develop a zero-injury culture. The same desire to eliminate product mistakes is at work when it comes to reducing injury rates. Presented here are the six levels, or six sigmas, in safety. Each "sigma control" builds on the previous level until the sixth sigma-a zero-injury culture-is attained.
