ABSTRACT
Six Sigma is a comprehensive and ¨exible system for achieving, sustaining, and maximizing business success (Everett Decision Systems 2011). 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 (The Six Sigma Way 2000). Six Sigma strives to improve quality, productivity, and bottom-line ’nancial performance. The Six Sigma approach provides a methodology to achieve these successes and a system on which to base any improvement initiative, including an energy and GHG minimization program. 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 way to conduct experiments, compare data, and provide important information about a process to ’nd the causes of problems and draw conclusions. Six Sigma methodologies are broken into six fundamentals as related to energy and GHG minimization:
• De’ne 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 the process and eliminate energy and GHG. • Measure and analyze performance.
