Quality cost report:
Prevention costs
- Machine maintenance expense $11,000 $11,000
Appraisal costs
- Inspection cost $15,000 $15,000
Internal failure cost :
- Scrap & rework $10,600
- Machine breakdown costs $5,400 $16,000
External failure costs :
- Warranty expense $34,000
- Product returns due to defects $6,000
- Estimated lost sales due to poor quality $10,000 $50,000
Total quality cost $92,000
b) What percentage of sales revenue is being spent on prevention and appraisal activities?
total sales revenue = $500,000
prevention and appraisal costs = $26,000
% = $26,000 / $500,000 = 5.2%
c) What percentage of sales revenue is being spent on internal and external failure costs?
internal and external failure costs = $66,000
% = $66,000 / $500,000 = 13.2%
