What Is Six Sigma?

Abstract

Analytical statistics involves the evaluation of ratio (or measured) data. A Six Sigma process is virtually defect-free, with only 3.4 defects in a million opportunities. Six Sigma is a performance management system for executing business strategy. It aligns improvement efforts to business strategy and business goal metrics. Six Sigma is a disciplined and data-driven methodology to improve, design, and manage processes, by focusing on improving business performance and meeting customer requirements. Six Sigma is the "best of the best"—meaning a Six Sigma strategy takes the best of the quality principles and techniques used over many years and applies them appropriately to an organization. Six Sigma helps in finding out and fixing the mistakes, errors, defects, and deviations (variations) involved in every aspect of delivering customer wants. By taking the best principles and techniques from each of these programs, organizations maximize their productivity, profitability, growth, and improvements in measurable ways.
