The 21st century has brought new challenges to manufacturing and service organizations, and one of these important challenges is that the industry is constantly evolving (Maleyeff , 2012). As a result, the systems, processes and procedures of successful businesses will be able to evolve according to the ever-changing needs of the industry. Six Sigma is a method widely used today by manufacturing and service companies to provide a framework for continuous process improvement (Maleyeff, 2012). Six Sigma is a system used in both manufacturing and service organizations to maximize business success by minimizing defects and processes. variability (Krajewski, 2013). Although Six Sigma relies heavily on the principles of total quality management (TQM), its focus is different. It is based on a close understanding of customer needs; disciplined use of facts, data and statistical analysis, and diligent attention to managing, improving and reinventing business processes. Six Sigma focuses on reducing variation in processes as well as focusing processes on their target performance measures. Whether it's a defect, too much variation, or an off-target process, degrades process performance. Six Sigma is a rigorous approach to aligning processes to their target performance measures with low variability. Six Sigma encompasses problem-solving methodology and focuses on optimization and cultural change. Six Sigma achieves this goal by using a comprehensive set of statistical and mathematical tools and a well-defined methodology that quickly produces meaningful results. Adapting this methodology leads to a fundamental cultural transformation within the organization (Raisinghani, 2005). Six Sigma was initially developed...... middle of article...... Six Sigma in any organization is disruptive at first because it requires not only buy-in from senior management, but also a role active management in defining the project and allocating resources. It also requires extensive training of some of the best people in the organization, with the understanding that their role will be 100% dedicated to deploying Six Sigma activities. The training required to implement Six Sigma involves everyone in the organization. Basic training lasts one day and covers process mapping and an overview of designed experiments, hypothesis testing, measurement and process modeling. The green belt training is more comprehensive, including a week of statistical analysis, SPC and measurement systems analysis. Black belt training requires approximately one month of training, including ANOVA, game theory, and multivariate regression (Raisinghani, 2005).
