Abstract:

Currently, there are two distinct approaches to assist information technology managers in the successful implementation of office automation software. The first approach resides within the field of usability engineering, while the second approach is derived from the discipline of management information systems MIS. However, neither approach has successfully produced conclusive evidence that explains what characteristics facilitate system use as well as influence user acceptance of the system. This study reports on the validity of a new model, entitled the Power, Performance, Perception P3 model, that links the constructs of usability engineering to user acceptance. Additionally, speech recognition software SRS was used in an experimental setting to validate the P3 model. This research also examined the viability of employing SRS in an Air Force office environment. The results of this study failed to validate the P3 model. However, an alternate model for predicting user acceptance, the Usability Acceptance Model, did emerge from the research which showed that the usability metric of user satisfaction can explain 53 of the variance of user intention to use a new technology. Additionally, the results of this study indicate that users in a typical Air Force office environment would utilize SRS for text processing.
