FOUR ABSOLUTES OF QUALITY
MANAGEMENT
• As defined by Philip B. Crosby in his book Quality Is Free, the cost of
quality has two main components: the cost of good quality (or the cost of
conformance) and the cost of poor quality (or the cost of non-
conformance). As Figure 1 shows:
• The cost of poor quality affects:
• Internal and external costs resulting from failing to meet requirements.
• The cost of good quality affects:
• Costs for investing in the prevention of non-conformance to requirements.
• Costs for appraising a product or service for conformance to requirements.
•

16. FOUR ABSOLUTES OF QUALITY
MANAGEMENT (CROSBY, 1979)

17. COST OF POOR QUALITY:
INTERNAL FAILURE COSTS
Internal failure costs are costs
that are caused by products or
services not conforming to
requirements or customer/user
needs and are found before
delivery of products and
services to external customers.
Example: Rework
delays
re-designing

18. COST OF POOR QUALITY:
EXTERNAL FAILURE COSTS
• External failure costs are costs that are caused by
deficiencies found after delivery of products and services
to external customers, which lead to customer
dissatisfaction. Examples include the costs for:
• Complaints
• Repairing goods and redoing services
• Warranties
• Customers’ bad will

19. COST OF GOOD QUALITY:PREVENTION
& APPRAISAL COSTS
• Prevention costs are costs of all activites that are designed to
prevent poor quality from arising in products or services.
Examples include the costs for:
• Quality planning
• Supplier evaluation
• New product review
•
Appraisal costs are costs that occur because of the
need to control products and services to ensure a high
quality level in all stages, conformance to quality
standards and performance requirements. Examples
include the costs for:
• Checking and testing purchased goods and services
• In-process and final inspection/test
• Field testing
