    We are trying to establish a system that measures cost of poor quality(COPQ). The COPQ should include tip of the iceberg as well as iceberg below water.  I  am wondering how to assess the iceberg below water systematically. Once we have that system, I believe the six sigma project can be defined systematically and assess the financial benefit in terms of reduced COPQ.

    Read Juran’s Quality Handbook. In the 4th edition the section on Quality Costs is at pages 4.1 to 4.30. It breaks COPQ down into its standard components:
    Internal Failure Costs
    External Failure Costs
    Appraisal Costs
    Prevention Costs
    If you don’t own a copy (you should), try your local library.
