Marino is considering the following changes: (a) introducing quality-improvement programs whose net effect will be to reduce rework and expediting costs by 75% and materials and labor costs for servicing machine tools by 5%; (b) working with suppliers to reduce materials-procurement and inspection costs by 20% and materials-handling costs by 25%; and (c) increasing preventive-maintenance costs by 50% to reduce breakdown-maintenance costs by 40%. Calculate the effect of programs (a), (b), and (c) on value-added costs, nonvalue-added costs, and total costs. Comment briefly.
