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


Expected Duration
73 minutes

During the Improve stage of a project, specific tools allow a Six Sigma team to implement solutions to address the causes of an identified process issue. For example, a timely and productive application of kaizen allows an organization to eliminate waste, streamline processes, reduce costs, and create a Lean culture in the organization. Cost-benefit analysis is another important tool used to determine whether an improvement initiative is worthwhile or to select the best solution. In this course, you’ll learn about some of the common Lean tools used in continuous improvement, including kaizen and kaizen blitz, the plan-do-check-act cycle, and cost-benefit analysis. This course is aligned to the ASQ Body of Knowledge and is designed to assist Yellow Belt candidates toward their certification and to become productive members on their Six Sigma project teams.
