Lean Six Sigma Green Belt

Lean Six Sigma is a quality improvement methodology structured to reduce product or service failure rates to a negligible level. Six Sigma companies typically spend less than five percent of their revenues addressing and repairing quality problems.

To achieve these levels, the Six Sigma process encompasses all aspects of a business; including management, service delivery, and design, production, and customer satisfaction. As a philosophy, Six Sigma drives business culture and requires a nearly flawless execution of key processes, making Six Sigma a high standard for companies and individuals to achieve. By reducing process variation, Six Sigma frees an organization to focus on improving process capability. As sigma levels increase, the cost of poor quality decreases, and profitability increases. This is why Six Sigma is highly associated with the delivery of consistent, world-class quality.
