Operator Performance on Two Office Data Entry System Testbeds: Preliminary Analyses.

Abstract

This effort tested the effectiveness of two computerized data entry systems designed to improve operator efficiency and reduce the number of errors in Navy personnel records. Data were collected on operator performance times and the quantities of errors made using (1) a stand-alone system; and (2) a distributed data entry system that used an off-site computer in tandem with an on-site microprocessor. Preliminary analyses of data obtained were conducted to assess user acceptance so that modifications, if needed, could be implemented before the system was installed. Results showed that the distributed office data entry system provided a distinct advantage over the self-contained system in reducing errors in the information system without adding to the office workload. Also, using this distributed system to make changes resulted in a 75 percent time savings over the manual method. The time saved in making changes would be, by itself, a significant factor in evaluating the cost effectiveness of systems employing computer data bases. (Author)
