Course Number

For a Six Sigma team to start an improvement project, it must measure key performance indicators through various metrics. These performance metrics can be applied to any industry or process and provide a wealth of information regarding the current state of the process and identify areas for improvement. The key performance metrics are also a useful tool in analyzing whether changes and improvements made to a process are, in fact, adding the desired performance and leading to a better customer experience. |n In this course, you will learn how to calculate and use the most common performance metrics used in Six Sigma including the defects per unit, defects per million opportunities, the first time yield and rolled through yield, the cost of low quality, and the cycle and takt times. The course will also examine the importance of measuring variation, or sigma, in relation to some of these key metrics and the benefits that lie within achieving a six sigma level. |n This course is aligned to the ASQ Body of Knowledge and is designed to assist Yellow Belt candidates toward their certification and also to become productive members on their Six Sigma project teams.

Target Audience
Candidates seeking Six Sigma Yellow Belt certification and any other individuals involved in quality and process improvement at the organizational or departmental level
