Identify the four types of
quality costs and explain
how they interact.
. 2-67
Quality of Conformance
When the overwhelming majority of
products produced conform to design
specifications and are free from
defects.
. 2-68
Prevention and Appraisal Costs
Prevention
Costs
Support activities
whose purpose is to
reduce the number of
defects
Appraisal Costs
Incurred to identify
defective products
before the products are

. 2-69
Internal and External Failure Costs

Examples of Quality Costs
Prevention Costs

• Quality circles
• Statistical process
control activities
Internal Failure Costs
• Scrap

• Rework
Appraisal Costs
• Testing & inspecting
incoming materials
• Final product testing
• Depreciation of testing
equipment
External Failure Costs
• Cost of field servicing &
handling complaints
• Warranty repairs
• Lost sales
. 2-71
Distribution of Quality Costs
When quality of conformance is low, total
quality cost is high and consists mostly of
internal and external failure.
Total quality costs drop rapidly as the quality
of conformance increases.
Companies reduce their total quality costs by
focusing their efforts on prevention and
appraisal because the cost savings from
reduced defects usually overwhelm the
costs of additional prevention and
appraisal.
Total quality costs are minimized when the
quality of conformance is slightly less
than 100%.
