211TPM Case Study: Hydraulic Leak Reduction
Financial Savings
Average rework time per defect = 32 minutes
Reduction in manpower requirements = 6.8 hours/ day
Cost of rework = $34.00 per hour
Number of production days per year = 150 days
Warranty = $22,000 per year
Project investment = $50,000
I = 15% (minimum)
Annual cost savings with zero defects = $22,000 + (32/60)*$34*150 +
6.8*$34*150 = $59,400
Five- year ROI = 116%
Payback period = 0.97 years
Conclusions
The results from this project were far above what we expected, having
