Internal Failure

Internal costs are incurred when the quality system fails to deliver product that meets the specified requirements. Typical internal failure costs include such activities as:

  • Waste
  • Scrap
  • Rework
  • Resources required to dispose of non-conforming materials

These are sometimes referred to as the costs of ‘non-quality’.

External Failure

External costs are those incurred after the product has been released to the customer, such as:

  • Recall costs
  • Warranty repair, if applicable
