Performance Metrics for Six Sigma

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

Prerequisite
None

Expected Duration
79 minutes

Description
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.

Objective

Introduction to Performance Metrics

  • recognize performance metrics that are based on calculating defects or nonconformities
  • recognize characteristics of two approaches to measuring process performance
  • recognize characteristics of two approaches to measuring process performance

Defects per Unit (DPU)

  • calculate defects per unit (DPU)
  • use DPU calculations to plan a project

Defects per Million Opportunities (DPMO)

  • recognize examples of defect opportunities
  • calculate defects per million opportunities (DPMO)
  • use DPMO calculations to plan a project

Rolled Throughput Yield (RTY)

  • identify the definition of rolled throughput yield (RTY)
  • calculate FTY and RTY
  • use yield calculations to plan a project

Process Capability Indices

  • recognize the level of capability of a given process
  • calculate Cp and Cpk
  • use Cp and Cpk calculations to plan a project

Cost of Poor Quality (COPQ)

  • identify accurate statements about cost of poor quality (COPQ) and its use as a performance metric for planning Six Sigma projects
  • match types of cost of poor quality (COPQ) to corresponding examples
  • use COPQ as a metric to assist in planning a given Six Sigma project
