Examlex · Accepted Answer

The Answer is Quality costs, also known as the cost of quality (CoQ), are categorized into four main types. These costs are associated with the effort to maintain product quality and the consequences of failing to do so. Here is a list of the typical quality costs:

1. **Prevention Costs**: These are costs incurred to prevent defects from occurring in the first place. They include:
- Quality planning
- Training and education for employees
- Process control and improvement initiatives
- Supplier qualification and assessment
- Preventive maintenance on equipment
- Design and development of robust processes
- Investment in quality management systems

2. **Appraisal Costs**: These are costs associated with measuring, evaluating, or auditing products to ensure they meet quality standards. They include:
- Inspection and testing of incoming materials
- In-process and final product inspection and testing
- Product and process audits
- Calibration of measuring and test equipment
- Costs associated with destructive testing loss
- Supplier quality assurance activities

3. **Internal Failure Costs**: These are costs related to defects that are found before the product reaches the customer. They include:
- Scrap and rework
- Downtime caused by quality problems
- Retooling or modification due to defects
- Failure analysis and troubleshooting
- Excess inventory to buffer against defects
- Cost of wasted materials and labor

4. **External Failure Costs**: These are costs that occur after the product has been shipped to the customer and defects are found. They include:
- Warranty claims and replacements
- Returns and allowances for defective products
- Handling complaints and customer support for quality issues
- Product recalls and associated legal costs
- Lost sales and reputation damage due to poor quality
- Penalties for non-compliance with regulatory standards

Understanding and managing these quality costs is crucial for businesses to maintain profitability and customer satisfaction. By investing in prevention and appraisal costs, companies can often reduce the much higher costs of internal and external failures.
