Study Notes
- Four costs of quality are prevention, appraisal, internal failure, and external failure costs.
Prevention Costs
- These costs are incurred to prevent defects from occurring.
- Activities include: design reviews, quality training programs, process improvements, and quality planning.
- Examples: Investing in advanced quality control software, hiring quality assurance specialists, and implementing ISO 9001 standards
Appraisal Costs
- These costs are incurred during the production process to evaluate the quality of the product or service.
- Activities include: inspections, testing, and audits.
- Examples: Performing quality checks on components, running quality tests on finished products, inspecting raw materials, and conducting audits of processes.
Internal Failure Costs
- These costs are incurred when defects are discovered before the product or service reaches the customer.
- Activities include: scrap, rework, and downtime.
- Examples: Repairing defective parts before they ship, scrapping flawed products, reworking damaged or incomplete components, and lost production time due to quality issues.
External Failure Costs
- These costs are incurred when defects are discovered after the product or service reaches the customer.
- Activities include: field repairs, warranty claims, loss of reputation, and lost sales.
- Examples: Repairing faulty products in the field, issuing warranty replacements, dealing with customer complaints, and decreased sales due to a reputation for poor quality.
Hardest Cost to Evaluate
-
Of the four costs of quality, external failure costs are typically the hardest to evaluate.
-
Difficulty stems from the indirect and often unpredictable nature of these costs.
-
Identifying all related negative impacts on sales and reputation is complex.
-
Quantifying the loss of future business due to a damaged reputation is challenging, as it's hard to definitively connect a specific failure to a specific loss in revenue.
-
Determining the full scope of warranty claims, lost sales, and customer dissatisfaction is also often complex and time-consuming. Unhappy customers may not directly complain, making it hard to identify the full extent of these issues.
