| The continuing increase in end-user computing over the last twelve years requires that management determine the value of these systems to the organization. Previous studies have measured end-user satisfaction as a surrogate for system effectiveness and indicated the need for valid, reliable instruments. This study evaluated the effectiveness of a MIS in state government and examined the validity, reliability, and usability of a modified end-user satisfaction instrument. The results indicate that end-users are very dissatisfied. Significant differences were found between end-users' satisfaction and the system characteristics of importance. The satisfaction and importance scales demonstrated good criterion-related validity and nine of fourteen satisfaction cluster reliabilities were.70 or better. The instrument may be strengthened by restoring the original scaling and removing the weak items. A shorter instrument could be created using Parts II and III of the instrument, which demonstrated scale reliabilities of.91 and.93. |
