Software Evaluation and Choice: Predictive Validation of the Technology Acceptance Instrument.

Author List: Szajna, Bernadette;
MIS Quarterly, 1994, Volume 18, Issue 3, Page 319-324.
The article addresses the issue of usefulness and ease of use (U/EOU) software evaluation. The author describes the challenge: software evaluation can be complex, costly, and time-consuming. The article introduces a study of the Technology Acceptance Model that considers U/EOU and the influence that will have on the user's intention to use the software. The author reviews the previous literature, presents the research methodology involving 47 MBA students, and details the results. The author concludes that the instrument has good predictive value in terms of intention to use a software program, self-report usage, self-predicted usage, and attitudes towards use and choice.
