Overview/Description
Six Sigma is a business improvement methodology that begins by comparing the current state of a company's products and processes to their desired levels. The goal of the Define phase in the Six Sigma DMAIC methodology is to identify improvement opportunities that have the maximum potential for return on time, money, and resource investments. Knowing what projects to select for improvement requires an assessment and analysis of existing business processes. For a precise, objective, and accurate assessment of the existing processes, you need to have correct metrics and knowledge of where and how to use them. Later in a Six Sigma project, during the Control phase, the overall performance of business processes is recalculated to identify process improvement. This course will examine how and when to use the metrics and tools to select Six Sigma projects. The course explores some of the number-driven metrics, such as defects per unit (DPU), rolled throughput yield (RTY), defects per million opportunities (DPMO), and process capability indices. It also explains cost of poor quality (COPQ) as a metric used to assess and indirectly present the potential gains to the company if the quality of products and processes is improved. In addition, the course explores how failure modes and effects analysis (FMEA) is used to identify improvement opportunities that have the highest priority for Six Sigma teams. This course is aligned to the ASQ Certified Six Sigma Green Belt certification exam and is designed to assist learners as part of their exam preparation.

Target Audience
Candidates seeking Six Sigma Green Belt certification; quality professionals, engineers, production managers, and frontline supervisors; process owners and champions charged with the responsibility of improving quality and processes at the organizational or departmental level

Expected Duration (hours)
