Definition

Cost of Quality (CoQ) is a concept that examines the costs associated with ensuring that a product meets quality standards, as well as the costs arising from not meeting these standards. By measuring and reducing these costs, organizations can improve their financial performance and customer satisfaction.

Categories of Cost of Quality

  1. Prevention Costs: These costs are incurred to prevent mistakes and ensure quality from the beginning. Examples include:

    • Training
    • Quality planning
    • Process controls
    • Market research

  2. Appraisal Costs: These costs involve evaluating products to ensure they meet quality standards. Examples include:

    • Inspecting parts from suppliers
    • Testing products during manufacturing
    • Quality audits

  3. Internal Failure Costs: These are costs incurred when a product fails to meet quality standards before reaching the customer. Examples include:

    • Scrap
    • Repairs of defective products
    • Downtime

  4. External Failure Costs: These costs occur when the customer experiences a product that fails to meet quality standards. Examples include:

    • Investigating complaints
    • Replacing returned products
    • Warranty charges
    • Potential loss of customers if they switch to a competitor

Examples

  • Prevention Cost Example: A company invests in employee training programs to ensure all workers understand the quality standards and practices to prevent defects.
  • Appraisal Cost Example: Performing routine inspections of parts and products in a manufacturing plant to ensure they adhere to quality specifications.
  • Internal Failure Cost Example: The cost of materials wasted due to defective products identified during the manufacturing process.
  • External Failure Cost Example: Costs associated with refunds and repairs when customers return defective products under warranty.
