ABSTRACT
Lean Six Sigma is a comprehensive and exible system for achieving, sustaining, and maximizing business success [1]. It is uniquely driven by a close understanding of customer needs, disciplined use of facts, data, and statistical analysis, and diligent attention to managing, improving, and reinventing business processes [1]. Six Sigma strives to improve quality, productivity, and bottom-line nancial performance. The Six Sigma approach provides a methodology to achieve these successes and provides a system to base these improvement initiatives for corporations, nonprot groups, and government agencies. Six Sigma relies heavily on data, facts, and the use of statistical tools to study whether an improvement has been made. These statistical tools are a powerful aid in conducting experiments and comparing data and providing important information about a process to nd the causes of problems and draw conclusions. Lean Six Sigma methodologies are broken into six fundamental categories:
• Dene products or services. • Know the stakeholders and customers and their critical needs. • Identify processes, methods, and systems to meet stakeholders’ criti-
cal needs. • Establish a process of doing work consistently. • Error-proof process and eliminate waste. • Measure and analyze performance.
