COPQ Overview
Definitions
 All activities and processes that do not meet agreed
performance and/or expected outcomes
 Costs that would disappear if every task were always
performed without deficiency
 Actual Cost - Minimum Cost = COPQ

Traditional Cost of Poor Quality
(4-5% of Sales)
When quality costs are initially determined, the categories
included are the visible ones as depicted in the iceberg below.
Waste
Testing Costs
Rework
Customer Returns
Inspection Costs
Rejects
Recalls

As an organization gains a broader definition of poor quality,
the hidden portion of the iceberg becomes apparent.
Late Paperwork High Costs
Pricing or
Billing Errors
Excessive Field
Services Expenses
Incorrectly Completed
Sales Order
Lack of Follow-up

Quantifying the Potential Benefit

The ratio of the individual category costs to total costs
varies widely. Many companies exhibit ratios which look
like the following:
Quality Cost Category Percent of Total
Internal Failure 25 to 40
External Failure 25 to 40
Appraisal 10 to 50
Prevention .05 to 5
