Introduction to Six Sigma

Six Sigma is a metric, a methodology and a management system, all at the same time.

Six Sigma as a Metric

Six Sigma is a measure of quality that strives for near perfection. The statistical meaning of Six Sigma is having six standard deviations between the mean and the nearest specification llimit. A Six Sigma process is performing at a level that is virtually defect-free with only 3.4 defects in a million opportunities. (A defect is defined as anything outside of customer specifications. An opportunity is a chance for a defect to occur)

Six Sigma as a Methodology

Six Sigma is a disciplined and data-driven methodology to improve, design and manage processes, focusing on improving business performance and meeting customer requirements.

Six Sigma as a Management System

Six Sigma is a performance system for executing business strategy. It aligns improvement efforts to business strategy and leverages on meaningful metrics to monitor success.
