Consider a proposal to enhance the vision system used by a postal service to sort mail. The new system is estimated to cost $1.1 million and will incur an additiona $200,000 per year in maintenance costs. The system will produce annual savings of $500,000 each year (primarily by decreasing the percentage of misdirected mail and reducing the amount of mail that must be sorted manually). The MARR is 10% per year, and the study period is five years at which time the system will be technologically obsolete (worthless). The PW of this proposal is PW(10%) = −$1,100,000 + ($500,000 − $200,000)(P/A, 10%, 5) = $37,236. Determine how sensitive the decision to invest in the system is to the estimates of investment cost and annual savings.
