Abstract

The methodology used in evaluating a maintenance information system for the United States Postal Service is described. Maintenance inspectors filled out the forms and gathered the data while performing their normal maintenance and inspection duties. This combination of duties consumed 100 man-years. The study verified that the use of the computerized information system had exposed 19 million dollars in excess inventory. Corrections made in the system as a result of the study developed an audited savings by postal authorities of 4.2 million dollars (versus a total study cost of 1.6 million dollars).
