Performance Metrics for Six Sigma

Course details

In the Define phase of Six Sigma DMAIC, teams identify improvement projects that have the maximum potential for return on time, money, and resource investments. For an accurate assessment of these opportunities, you need to have correct performance metrics and knowledge of where and how to use them. Later, during the Control phase, performance is assessed again using the same metrics to ensure improvements have been achieved. This course explores some of these metrics, such as defects per unit, defects per million opportunities, rolled throughput yield, process capability indices, and sigma level. It also explains using cost of poor quality to assess the potential gains to the company if the quality of products and processes is improved. This course is aligned with the ASQ Body of Knowledge and is designed to assist Green Belt candidates toward achieving their certification and becoming productive members of their Six Sigma project teams.
