Quality improvement programs and cost savings Garber Valves Company manufactures brass valves meeting precise specification standards. All finished valves are inspected before packing and shipping to customers. Rejected valves are returned to the initial production stage to be meted and recast. Such rework requires no new materials in casting but requires new materials in finishing. The following unit cost data are available (see attached)
As a result of a quality-improvement program, the reject rate has decreased from 64% to 5.1%, and the number of rejects has decreased by (6.4% - 5.1%) x 10,000 units. Improvements in reject rates have also led to a decrease in work-in-process inventory from $386,000 to $270,000. Inventory carrying costs are estimated to be 15% per year. Estimate the annual cost savings as a result fo the quality improvement.
